nickel ore processing scavenger flotation in south africa

This study investigated the effects of flotation parameters on the recovery of low grade nickel sulphide ore. The parameters investigated are the particle size, flotation time, temperature and pH of the pulp. The analyses of the results obtained showed that particle size, pH, and flotation time had significant effects on the recovery of nickel sulphide ore

Jones has provided a comprehensive review of the downstream processing in South Africa of flotation concentrates. Although this is not a focus area of the present paper, it is worth noting that the flotation concentrates undergo smelting and converting to produce a PGM-containing nickel-copper matte

Nkomati Nickel mine, located on the Uitkomst Complex approximately 250 km due east of Pretoria, is currently the sole primary nickel producer in South Africa (Figure 1C, ). Although the Uitkomst Complex was described by Wagner [ 38 ], mining of the massive sulphide ore for its primary base-metal sulphide (BMS) and secondary PGE mineralization only began more than six decades later in 1996 [ 39 ]

Run-of-mine ore is processed at the concentrator plant on site, which was commissioned in 2011. The Unki smelter was completed and commissioned in 2018. The flotation circuit consists of a short residence time, primary roughing stage comprising 3x70m3 flotation cells

Some amounts of magnetite and chromite exist in the ore together with sulphide and oxide type nickel minerals. The ore sample contains 1.32% Ni, 10.79% SiO2, 78.39% Fe2O3, 1.3 g/t Ag, and 1.0 g/t

Nov 01, 1991 · A solution of sodium amyl xanthate and Dowfroth 1263 frother are added to the non-magnetic portion to float first a bulk copper-nickel concentrate, then after the addition of more collector a scavenger concentrate is floated that is combined with the mag- netic pyrrhotite concentrate to form the rougher pyrrhotite concentrate

Froth flotation is a very important mineral concentration process that is used to recover a vast array of different minerals containing valuable commodities such as copper, lead, zinc, nickel, molybdenum, tungsten, silver, gold, phosphate and potash. In the flotation process, ore is ground to a size sufficient to adequately liberate desired minerals from waste rock (gangue); it is conditioned as a slurry using

The ore is processed through a conventional flotation concentrator that consists of a simple crushing and grinding circuit, rougher, scavenger and cleaner flotation cells, followed by concentrate and tailings thickeners. The end product is a nickel-copper-cobalt-PGM concentrate, which is

SNF CHEMQUEST South Africa is a preferred channel for the South African Mining industry. Mining operations using a wet process will use speciality mining reagent or flocculants at various stages of their operation: mining and primary crushing, beneficiation plant including flotation concentrators, hydrometallurgical and metal refining processes

This project was reconstruction project. It was South Africa 8000t/d platinum and 3000t/d chromite flotation system. The mineral processing flow was two-stage coarse - one-stage scavenging - three-stage concentrating flotation process

WO2007039663A1 Processing of nickel sulphide ore or . The present invention relates to a new hydrometallurgical process for recovering nickel from nickel bearing raw materials, such as sulphide flotation concentrates. In general, the process involves the oxidative atmospheric pressure leaching of nickel sulphide concentrates using a sodium

May 01, 2014 · Pyrrhotite (Po) is one of the most abundant sulfide minerals in processing industry and must be rejected in most cases. Particularly, Po rejection and its selectivity against pentlandite (Pn) have long been a challenge due to similarities in the mineral composition of the two minerals and the collectorless flotation characteristics of Po

In early 2001, Zimplats announced the development of Ngezi into a 2.2Mtpa open pit operation producing 208,000oz/y of platinum-group metals, plus nickel, copper and cobalt. Ore from Ngezi is treated in the Selous Metallurgical Complex at Selous, thus reviving at least part of the original project, although the refinery section remains on care
