Gold and copper recovery from flotation concentrates of ...

24.01.2018  The authors present the data on the substance analysis of gold–copper–arsenic flotation concentrate. Gold and copper recovery by autoclave leaching of the concentrate has been studied. It is found that maximum gold and copper recovery under optimum conditions reaches 96 and 92%, respectively. The profitability of the proposed process flowsheet is

The intensive Leaching of Gold Concentrates Containing ...

01.01.2002  The hypotheses for these test work phases are:The intensive cyanidation leaching process is an effective method of the recovery of gravity gold concentrates.The ammonia-cyanide leaching process increases the selectivity of gold extraction over copper extraction in gold concentrates containing cyanicides.Two different concentrates were used in this

Bioleaching of copper, zinc and gold from a polymetallic ...

is the first study of the microbiological leaching of copper, zinc and gold from a polymetallic ore flotation concentrate from the Čoka Marin deposit (Serbia).

Accelerated leaching of gold, silver and copper-gold ores ...

Conventional processing approaches for copper-gold ores • Gold ores with nuisance copper levels (oxide ores): –High cyanide addition, high pH, significant WAD CN production. • Gold ores with economically recoverable copper (oxide ores) –Acid (heap) leach followed by cyanidation. • Economically recoverable base metals (sulfide ores)

Sulphide Gold Ore Treatment by Leaching and Flotation Process

18.04.2016  Sulphide Gold Ore Treatment by Leaching and Flotation Process. Post navigation. Previous. Next . 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

The leaching and adsorption behaviour of gold ores

The flotation feed and copper concentrate showed an enhancement in gold extraction due to the activated carbon adsorbing gold that would otherwise have been preg-robbed. However, this mechanism did not explain the behaviour of the pyrite concentrate. For this ore the enhanced extraction was due to a combination of equilibrium and preg-robbing effects. Diagnostic

Arsenic leaching from a gold bearing enargite flotation ...

01.04.2009  The gold is refractory to direct cyanidation but potentially economic concentrations of enargite–luzonite are contained in the ores. Thus, the ores have been beneficiated by flotation, recovering the gold and copper in a collective concentrate destined for further processing via pyrometallurgy (Ghiani et al., 2000, Curreli et al., 2005 ...

DEVELOPMENT OF A GLYCINE-CYANIDE LEACH PROCESS FOR GOLD

Products include gold doré and copper concentrate. In all flotation processes, a trade-off exists between mineral concentrate grade and recovery. The severity of this trade-off is very dependent on the nature of the ore body (i.e. mineral types and textures with respect to both gangue and value minerals and the relative concentrations of each), the adopted grind size and the applied
