Feb 21, 2018 2. Geology. In South Africa, the PGM ore is mined in the western and eastern limb of the Bushveld Igneous Complex [].Within the Bushveld Igneous Complex, the Merensky reef, the Platreef and Upper Group 2 (UG2) reef are exploited for platinum production [1, 4, 9].Merensky and Platreef have similar chemical and mineral composition [6, 10].These reefs

The definition of the process flow sheet was completed after an exhaustive option trade-off study, which looked at various flow sheets. The major options considered in a detailed trade off were: • primary crushing and SABC with either conventional crushing or HPGR in-circuit pebble crushing •3 and 4 stage conventional crushing followed by

Platinum ore is mined from the Merensky and the UG2 reefs, the two main … During concentration process, the ore is ground into fine particles with the aim of ….. Electrostatic or charge stabilization – this is the effect on particle interaction due … More detailed

Dec 17, 2012 The UG2 ore is richer in chromite but contains lesser nickel and copper sulphides compared to Merensky ore. The Union Mine project lays more emphasis on the extraction of the UG2 Reef ore because it has a higher density and its ore is relatively more friable, which reduces its treatment cost significantly compared with Merensky’s ore

Crushing processing sandstone sandstone crushing processing technology at present mainly has the following kinds. 1, crushing process directly.Its technological process is: the run of mine ore – grizzly – jaw crusher crushing and screening to cone crushing and screening, more paragraphs to roll the crushing and screening – products

The ore needs to be crushed, as a choc chip biscuit, to get the minerals out. Once we have crumbled the choc chip biscuit, the chocolate pieces can be separated from the crumbs. In the same way in the mining process the valuable minerals can be separated from the unwanted rock. The unwanted rock is called waste rock

Mar 14, 2018 When the iron ore is extracted from the mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher’s CSS before the crushing stage. A static screen is used to divert the fine particles for crushing

Sep 09, 2016 Crushing & Grinding. The purpose of crushing and grinding is to reduce the size of the potential ore particles to that where there is sufficient REE mineral liberation and the size/size distribution is suitable for the chosen downstream mineral recovery process. This allows for the subsequent REE mineral recovery processes to function in an

Feb 01, 2012 The plant is running between 900 and 1,000 tonnes of ore per hour into the mill, a world best for platinum, according to section engineering manager Natalie Fourie. Mogalakwena North also has the biggest primary gyratory crusher in the world, weighing 480 tonnes with an 18 m diameter and 1 MW motor

Ore processing is a 24 hour operation. Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along

Top view of Colina camp at the Cobre Panama copper mine. Ore processing will be carried out in a concentrator designed to treat ore at a head grade of 0.70% Cu and 0.013% Mo. The concentrator will initially process 150,000tpd of ore from Botija while ore from the Colina and Valle Grande pits will be. Get Price

The Merensky contact is crushed to -16mm, fed to a DMS plant to remove waste, and re-crushed. The pothole reef also undergoes two-stage crushing but bypasses the DMS. The Merensky crusher products are combined for two-stage milling/flotation and filtration. The UG2 and Merensky concentrates are dispatched separately

All footwall norite and Merensky pyroxenite of sortable size is picked out and thrown back on to the face scatter-pile. The ore remaining is then shovelled 30 feet down dip and 10 feet up dip to the panel track, where it is loaded into ⅓-ton cars, trammed along the gully track and tipped into the central gully scraper path

The BRPM concentrator, was designed to receive Merensky ore from BRPM’s two decline shafts and is able to treat 10% of UG2. The original design capacity of 200ktpm, was upgraded to 250ktpm to accommodate production from Styldrift. The concentrator can be described as a robust maintenance intensive environment which produces 2.7 tonnes of

The aforementioned is contrary to traditional narrow tabular Merensky and UG2 stratigraphy with recognized local changes in the planarity of the ore bodies, which are mostly related to the different fancies types. The Merensky and UG2 reefs are both sulphide enriched with the Merensky reef being the main economic horizon mined at RBPlat

Sep 01, 2000 The platinum-bearing sulfide ore from the Merensky Reef in South Africa's Bushveld Igneous Complex had a complex mineralogy, consisting mainly of silicates, oxides and base metal sulfides. The main base metal sulfides were pyrrhotite, pentlandite, chalcopyrite, pyrite and several other sulfides (Vermaak and Hendricks, 1976)

The relative density of Merensky ore is 3.2 and that of UG2 ore is 4.3. 15. b) Crushing costs are lower because UG2 ore is more friable. Milling costs are also lower. c) Flotation reagent costs are much lower, because Merensky ore requires the use of a talc depressant
