  Recover PGM by Matte Smelting and Leaching - 911 …

  202116 · Smelting the concentrates with a lime, fluorspar, and silica flux resulted in the recovery of 94 pct of the metal values in the matte. Leaching the ground matte with dilute H2SO4 selectively extracted more than 99 pct of the nickel and iron. The first-stage residue contained 99.9 pct of the copper and PGM values.

  Distribution of Copper, Nickel, Cobalt and Iron between …

  An experimental study of the equilibrium between the bottom phase (sulfide melt or copper) and slag in neutral and oxidizing atmospheres yielded dependences of the content of dissolved copper, nickel, and cobalt in the slag on that of sulfur in the sulfide melt and also the dependence of the content of dissolved copper and nickel on that of nickel in the …

  The Direct Leaching of Nickel Sulfide Flotation Concentrates …

  2022713 · The iron-to-magnesium ratio in the nickel concentrates destined for smelting is a key parameter that influences smelting temperature and slag viscosity (Mayhew et al. 2013; Senior and Thomas 2005 ), hence emphasis is placed on the rejection of Mg-bearing gangue during flotation of nickel sulfide ores (Lotter et al. 2008; Pietrobon et al. …

  Selective flotation of enargite from copper sulphides in …

  2017101 · Recent research has demonstrated promising results showing the possibility of separating arsenic-copper sulphides from other copper minerals by controlling the potential of the flotation pulp. Most of these studies were conducted on single mineral systems, and the selective removal of arsenic-copper minerals in real ore systems is not …

  Recovery of pyrite from copper tailings by flotation

  201991 · Abstract Tailings that are generated in the copper concentrate production contain great amount of sulfide mineral, in particular pyrite. Pyrite in contact with water and oxygen might oxidize spontaneously and originates a serious environmental problem. In this article the recovery of pyrite before storing it in the tailing deposit to produce pyrite …
