Zircon, monazite, rutile, chromite, kyanite and staurolite show low variability, which is probably associated with high resistance of minerals for abrasion during transportation and diagenesis. The depositional model of the Namalope deposit, in the flat area and wet concentrate plant B in particular, suggests deposition in a shallow marine environment associated with regression for deposition of Unit 6, 7 and 9 and transgression during deposition of Unit 82. The spatial distribution of heavy minerals in the Namalope deposit and its environment of deposition are the key points for discovery of new deposits around the Namalope with the same characteristic of mineral assemblage and they are used for mine strategic plans such as update block model and mine design.]]> Wed 12 May 2021 19:01:48 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:7861 Wed 12 May 2021 18:55:24 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:7315 Wed 12 May 2021 18:54:01 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:7311 Wed 12 May 2021 18:35:11 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:11721 Wed 12 May 2021 18:23:13 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:9228 Wed 12 May 2021 17:55:15 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:9315 Wed 12 May 2021 17:45:32 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:8872 Wed 12 May 2021 17:35:19 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:9674 Wed 12 May 2021 17:32:30 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:11699 Wed 12 May 2021 17:29:57 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:1084 Wed 12 May 2021 17:27:16 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:8480 Wed 12 May 2021 17:20:50 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:9187 Wed 12 May 2021 17:18:56 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:11700 Wed 12 May 2021 17:12:09 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:29413 Wed 12 May 2021 16:52:31 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:11795 Wed 12 May 2021 16:42:17 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:5997 Wed 12 May 2021 16:31:58 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:823 Wed 12 May 2021 16:31:10 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:10163 Wed 12 May 2021 16:24:56 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:8346 Wed 12 May 2021 16:23:47 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:9413 Wed 12 May 2021 16:19:42 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:5998 Wed 12 May 2021 16:15:50 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:9193 Wed 12 May 2021 15:56:44 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:5848 Wed 12 May 2021 15:53:39 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:5151 Wed 12 May 2021 15:47:42 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:42031 Wed 12 May 2021 13:54:18 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:1155 Wed 12 Jul 2023 08:28:48 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:29033 Wed 10 Aug 2022 07:08:59 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:28605 Tue 13 Jun 2023 12:32:30 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:38436 Tue 09 Aug 2022 05:28:24 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:35644 Tue 09 Aug 2022 05:24:53 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:71896 Tue 09 Apr 2024 15:19:44 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:71899 Tue 09 Apr 2024 14:37:43 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:38015 Tue 06 Jul 2021 09:22:40 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:69149 Thu 19 Oct 2023 11:30:53 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:69148 Thu 19 Oct 2023 11:26:52 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:69146 Thu 19 Oct 2023 11:18:34 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:69142 Thu 19 Oct 2023 11:06:37 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:11796 Thu 13 May 2021 12:34:15 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:26580 99 % in selectively extracting the metalloporphyrins. The impact of the template on the affinity of recognition for NTPP was evaluated. The results showed that the NTPP adsorption capacity increased as the molar ratio of NTPP to styrene was increased from 1:1 to 3:1. The optimal ratio of template to functional monomer which yielded the best specific affinity and highest recovery (99.9 %) was 3:1. The effects of trifluoroacetic acid (TFA), dichloromethane (DCM), dimethyl sulphoxide (DMSO), pentane (PEN) on electro-spinnability of the polymer solutions and the morphological appearance of the nanofibers were investigated. The imprinted nanofibers exhibited the same selectivity specialism for both NTPP and VTPP. A remarkable stability in relation to reusability was observed when imprinted nanofibers were used, as they could be reused nine times without incurring any significant loss in removal efficiency. The results were validated by analysing a certified reference material. The imprinted sorbents were therefore found to be selective sorbents that are well suited for handling trace metals in organic media.]]> Thu 13 May 2021 09:54:20 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:9390 Thu 13 May 2021 08:49:54 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:8529 Thu 13 May 2021 07:30:45 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:4113 Thu 13 May 2021 07:20:46 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:10670 Thu 13 May 2021 07:19:36 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:5969 Thu 13 May 2021 07:08:53 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:4171 Thu 13 May 2021 06:53:01 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:7875 Thu 13 May 2021 06:50:52 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:7883 Thu 13 May 2021 06:15:41 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:3211 Thu 13 May 2021 06:11:58 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:1154 Thu 13 May 2021 06:00:53 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:38246 Thu 13 May 2021 05:41:00 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:10183 Thu 13 May 2021 05:27:34 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:26609 2.5Ga) and are located to the south and east of Lake Victoria on the Tanzania craton. The Tanzania Craton is surrounded by Usagaran 1.9 Ga rocks (the east African orogenic belt (EAO) better known as the Mozambique belt) to the east and the Ubendian belt to the south and west. Published reports show that the eastern part of the Tanzania Craton is dominated by the fragments of Archaean rocks. Metamorphism along East Africa and the Tanzania Craton is due to several geological events. These geological events include the intrusion of granites in the Archaean Tanzania Craton (3 Ga), subduction of ocean plate resulted to the formation of Usagaran belt (1.9 Ga), opening and closure of Mozambique Ocean, which resulted in the formation of the Mozambique belt between 700 – 800 Ma and the Pan African orogeny at 640 – 620 Ma, which is associated with the formation of Gondwana. It is believed that fragments from the Archaean Tanzania craton were re - metamorphosed during these events. The Handeni project (the focus of this thesis) is located in the northern portion of the eastern part of the Usagaran belt (1.9 Ga) comprising the eastern part of Archaean Tanzania Craton. The area is characterized by Proterozic rocks of basaltic composition. The documented 2.7 Ga rocks at the Kilindi Handeni Superterrane at the northern part of the Usagaran belt correlate well with 2.7 Ga of Nyanzian rocks of Archaean Tanzania craton. The Handeni project area is geologically dominated by metamorphosed and deformed units of quartzofeldspathic gneisses, migmatitic gneiss, garnet silicified rock, garnetiferous amphibolite, garnetiferous granulite, graphitic schist and hornblende pyroxenite. Intensive deformation features that were developed include folds (sheath folds, micro and macro scales), faults, shears and regional thrusts. This thesis focuses on identifying the protolith of the rocks, alteration minerals, and metamorphic assemblages in the project area in order to understand the timing of gold mineralization. Geological investigation of core, ore petrology and mineralogy, mineral composition by using JEOL microprobe analysis and XRF analysis of bulk rocks were utilized. All the analytical work was done at the Geology laboratory, Rhodes University. Petrographic analysis shows that the rocks sampled in the study area are characterized by alteration minerals such as calcite, dolomite and sericite. Sulphide minerals including chalcopyrite, pyrrhotite, pyrite, pentlandite and gersdorffite were identified. Gold mineralization is associated with disseminated sulphides in association with trace amounts of base metals. Four rock types were proposed as host rocks for the mineralization, namely garnet silicified rock with superimposed quartz veins, garnetiferous amphibolite, garnetiferous granulite and hornblende pyroxenite. Fold troughs, filled fractures associated with episodes of folding, quartz veins and shear zones are suggested as gold precipitation sites. The presence of high grade metamorphic rocks containing gold, intermediate to low grade assemblages with sulphides and associated hydrothermal alteration as well as a complex deformation history suggests that the Handeni mineralization took place over an extended time period stretching from a ductile to a brittle environment.]]> Thu 13 May 2021 05:05:57 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:11210 Thu 13 May 2021 05:03:31 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:10490 Thu 13 May 2021 04:45:48 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:8871 Thu 13 May 2021 04:25:41 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:11516 Thu 13 May 2021 03:32:17 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:4457 Thu 13 May 2021 03:30:35 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:1975 Thu 13 May 2021 03:19:46 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:5846 Thu 13 May 2021 03:19:43 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:9181 Thu 13 May 2021 03:07:07 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:8329 Thu 13 May 2021 02:59:07 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:8798 Thu 13 May 2021 02:16:23 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:11283 Thu 13 May 2021 02:04:23 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:29503 Thu 13 May 2021 02:01:21 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:8935 Thu 13 May 2021 01:59:15 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:8312 Thu 13 May 2021 01:58:57 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:5847 Thu 13 May 2021 01:12:18 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:26517 Thu 13 May 2021 01:02:42 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:10346 Thu 13 May 2021 00:51:42 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:10433 Thu 13 May 2021 00:50:43 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:4774 Thu 13 May 2021 00:35:10 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:7868 Thu 13 May 2021 00:35:05 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:11770 Thu 13 May 2021 00:32:51 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:8314 Thu 13 May 2021 00:29:05 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:11284 Thu 13 May 2021 00:16:13 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:1962 Thu 13 May 2021 00:08:05 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:11338 Thu 13 May 2021 00:08:03 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:6971 Mon 14 Aug 2023 12:18:13 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:64122 Mon 08 May 2023 12:57:04 SAST ]]>
