A process mineralogical study based on three texturally and mineralogically different chromite-bearing ore types at the Nkomati nickel mine was undertaken, with focus on chromite. Chromite is a by-product of the Ni-Cu-Co-PGE ore at Nkomati Nickel mine. These being the PCMZ_MG (medium-grade Ni-Cu sulphide silicate ore with …
A grinding/flotation pilot plant was operated at the SGS facilities in South Africa, to produce several hundred kilograms each of pyrite concentrate and scavenger tailings, which were then shipped to Canada for piloting of the downstream process at the SGS facilities in Lakefield, Ontario. The downstream POX, atmospheric leaching,

Dissolved Air Flotation. Dissolved Air Flotation is an effective clarification system used for clarification and sludge thickening. Designs are compact and package plants can be tailor made for the treatment of water vegetable oil, oily waters, dairy, butter, margarine, canning, starch, latex, textile, carpet, food processing, and fish processing effluent.
The traditional approach for the beneficiation of South African siliceous sedimentary phosphate ores has been reverse cationic flotation. The robustness of this approach, however, has been a concern due to its sensitivity to parameters such as slimes content, headgrade (P 2 O 5 and SiO 2 content), reagent dosages and conditioning …
The BIC is the largest known repository of PGE global resources, primarily in the Upper Group 2 (UG2), Merensky Reef, Platreef, and the BIC satellite intrusion, Nkomati Nickel Deposit (Blengini et al., 2020; USGS 2022).South Africa remains the world's top producer of platinum and the second-largest producer of palladium (McFadzean et al., …
and flotation processing practice of treating PGMs in South Africa and Russia the world's leading producers of PGEs. 2. Geological Occurrence and Mineralogy of the Ore Bodies 2.1. South Africa In South Africa, the PGM-bearing ores are found in the Bushveld Complex, which contains extremely rich reserves of these minerals.
relatively few areas of the world; South Africa (88%), Russia (8%), North America (2%), Zimbabwe (1%) and Rest of World (1%) South Africa (SA) is the source of over 60% of newly mined PGMs and over 80% of Platinum. PGM mining in South Africa is located in the Bushveld Complex in three regions commonly referred to as the Western,
Chrome and PGM recovery plants: Feed sources: Tailings dumps: Production capacity: 35 000 tonnes per month: First year of operation: 2011 (acquired by Sylvania in 2018) Note: deviates from typical SDO Process flow due to absence of current arisings and presently no secondary milling and flotation circuit
PLANT PRACTICE Before discussing the details of auriferous sulphide flotation some background discussion on the different flotation operations in South Africa and Australia is presented. 1057 1058 C.T. O'CONNOR and R. C. DUNNE South Africa The flotation process in South Africa can be broadly categorized into two areas, …
The Imhoflot G-Cell, a new development in the pneumatic flotation technology (which incorporates centrifugal forces in the separating vessel) is a recent innovation in the mineral processing world.
Ultimate Flotation means multi-patented South African technology, setting the benchmark for world-class flotation technology. Patented innovation means highly efficient …
Some early fundamental research was done on DAF at the University of Cape Town (Bratby and Marais, 1975a,b). The initial interests in South Africa were about DAF for treating sewage effluents and for thickening, but by the late 1970s DAF was examined to treat eutrophic water supplies culminating with construction of several plants in the …
About 80% of the worlds' reserves for platinum group metals (PGMs) are in South Africa's Bushveld Igneous Complex. Processing of PGM involves comminution, flotation, smelting, converting, base metals refinery and precious metals refinery. Due to increasing chrome content in the feed and the challenges associated with operating high …

INTRODUCTION The dissolved air flotation (DAF) process has since the seventies established itself as an efficient solidsliquid separation technique for various applications. ... In Southern Africa, pilot-plant studies performed in the early sixties resulted in the DAF process first being applied in 1969 to algae removal as part of a 4.5 …
Depending upon the age of the flotation plant, a wide range of flotation equipment can. ... concentrates from the flotation process. ... Pd is mainly produced by South Africa and Russia, which ...
Froth flotation is the follow-on operation, after comminution and classification, in the process of liberating and separating minerals by exploiting the differences in physical …
and at one other conventional plant, dense media separation is used to sepa-rate the barren norite stringers from the heavier chromite reef before milling and flotation. In one of the older converted plants, mills as small as 2.45 m ¥ 2.45 m (350 HP) are still in regular use, but the more modern plants are utilizing larger
modular process sections, and even whole concentrators. Maximum efficiency Our wide range of cell sizes enables plants to be more compact, economical, and efficient. Fewer units in a flotation plant lead to substantial savings in capital expenditure, while our reliable equipment delivers high availability and contributes to
The process plant also has two floatation circuits. Sulphide minerals are separated first, and tailings from the sulphide roughers are sent to an oxide circuit. ... of South Africa, has supervised the building of the processing plant – these two are the EPCM contractors – and Turgis Consulting (Pty) Ltd, also of South Africa, has designed ...
