leaching process of flotation concentrate

BIOLEACHING OF GALENA FLOTATION CONCENTRATEBioleaching of galena flotation concentrate 285 bacterial activity decline. The surface of galena is then covered with a passive film of lead sulphate, which makes further process of galena oxidizing impossible. The redox potential stays at low unchangeable levelLeaching of a copper flotation concentrate with .Abstract The leaching behavior of a copper flotation concentrate was investigated using ammonium persulfate (APS) in an autoclave system. The decomposition products of APS, active oxygen, and acidic medium were used to extract metals from the concentrate.

A maximum recovery of Cu (95%), Zn (90%), Ni (40%) and Co (50%) was observed after 5-7 hours of leaching at 90C in the oxygenated solutions containing 20-30 g/dm3 of Fe(III).Kell hydrometallurgical extraction of precious and base metals from flotation concentrate.on concentrate flotation recoveries and smelter payabilities in the PGM industry. In response to these constraints, Kell was initially conceived by one of the authors (KL) and subsequently further developed (Liddell et al., 2011; Liddell and Adams, 2012). KellSulphide Gold Ore Treatment by Leaching and Flotation .Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return. This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an ...COPPER EXTRACTION BY BIO-LEACHING OF FLOTATION COPPER SULPHIDE CONCENTRATESFigure 1 Bio-leaching mechanisms: Direct and indirect ones (Smith & Misra, 1991) EXPERIMENTAL Flotation Concentrate The sulphide concentrate used in the experiments is the result of the copper sulphide flotation process from a primary ore (underground

Leaching silver flotation concentrates to produce dore .

Leaching silver flotation concentrates to produce dore on site. A large proportion of the world's silver is produced as silver flotation concentrate and is sold to smelters for treatment. This incurs costs in smelter charges, transport and often extra taxes. The ILR has the ability to add value by treating silver flotation concentrates to recover ...BIOLEACHING OF COPPER SULPHIDE FLOTATION .Flotation Concentrate The flotation process is known as one of the methods that can separate minerals based on differences of surface properties of minerals.
