WO2009068735A1 - Method for processing pyritic

The invention relates to a method for processing pyritic copper sulphide concentrate, in which, in addition to copper, there is arsenic and gold bound to the sulphide minerals, or invisible gold. In the method concentrate is leached into a chloride-containing solution. Raw material leaching is performed in conditions where the copper, iron and arsenic of the raw material dissolve, but the gold ...

Rcovery of gold in pyritic ores - Mine Engineer.Com

The most difficult particles to gravity concentrate are the fines, and 75 microns to 2 microns are definitely very fine. So, even if the ore were ground to 2 microns, it may not be recoverable using current gravity technology. That appears to leave froth flotation as still the best method of recovering the gold from pyritic ores. Sulfide ores ...

Chloride–hypochlorite leaching of gold from a

In this research, effect of mechanical activation on the chloride–hypochlorite leaching of gold from a refractory pyritic concentrate containing ca. 27 g/t gold was investigated for the first time.Results showed that after 30 min leaching, 100% of gold was extracted from a 45 min-milled sample while only 37.2% of gold was obtained from the un-milled sample after 480 min leaching (at 25 °C ...

Gold extraction - Wikipedia

The solubility of gold in a water and cyanide solution was discovered in 1783 by Carl Wilhelm Scheele, but it was not until the late 19th century, that an industrial process was developed.The expansion of gold mining in the Rand of South Africa began to slow down in the 1880s, as the new deposits being found tended to be pyritic ore.The gold could not be extracted from this compound with any ...

In this work, we proposed a method for biohydrometallurgical processing of mining (old pyritic flotation tailings) and metallurgical (slag) wastes to recover gold and other nonferrous metals. Since this processing allows the removal of toxic metals or at least decreases their content in the solids, this approach may reduce the negative environmental impacts of such waste.

Extraction of Gold

The extraction of gold by the cyanide-method is of great technical importance. It is effected by lixiviation with a solution of potassium cyanide, the gold being precipitated either by addition of zinc or electrolytically. The process was suggested by Mac Arthur and Forrest in 1385, and is based on the well-known solubility of gold in potassium-cyanide solution, a phenomenon said to have been ...

Gold Processing Methods Gold Ore Extraction

Of all the methods of extracting gold processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets. This page offers a comparative review of gold recovery ...
