Roasting and leaching a sulphide concentrate This 2000-ton per day plant is operating on an arsenical gold ore in the Duparquet area of Quebec, Canada. The operation consists of straight flotation, followed by roasting and cyaniding of the concentrates.
SUBSTANCE: invention relates to method of processing sulphide gold containing arsenic concentrates. Method involves mixing, annealing, treatment of gas phase and cinder leaching with extraction of gold, silver, nonferrous and rare metals. Batch is prepared by mixing concentrate with ammonium chloride in weight ratio of 1:0.3–1:3.0.
USB1 - Method for processing refractory auriferous ... The present invention involves a method for processing refractory sulfide ores to facilitate gold recovery without the burden of pressure oxidizing or roasting a whole ore and without the substantial loss of gold value associated with preparation of an ore concentrate by conventional flotation.
method for processing pyritic concentrate containing gold, copper and arsenic 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.
The present invention relates to a process for chemical extraction of gold and silver from low grade and refractory pyritic concentrates containing minimum 1 ppm Au, by their leaching in enamelled cast iron reactors, steel plated lead or plastic coated steel, at room temperature, in ammoniac solutions (pH 8-10) of sodium thiosulfate (50-60 g/l Na 2 S 2 0 3 • 5 H 2 O) with a divalent copper ...

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 ...
Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold.The color has also led to the nicknames brass, brazzle, and Brazil, primarily used to refer to pyrite found in coal.. The name pyrite is derived from the Greek πυρίτης λίθος (pyritēs lithos), "stone or mineral which strikes fire", in turn from ...
Generally, recovery of the gold from the sulfide concentrates requires further processing, usually by roasting or wet pressure oxidation. These pyrometallurgical or hydrometallurgical treatments are themselves usually followed by cyanidation and carbon adsorption techniques for .
When the goal of a pyritic gold flotation is to produce sulfuric acid by roasting the concentrate, the need to maintain sufficient pyrite grade for self-roasting can result in significant gold losses.
The extraction of gold/silver from a copper-bearing pyritic gold concentrate (62 g/t Au, 110 g/t Ag and 0.3% Cu) in thiosulphate solutions was investigated in this study.
Alternative methods of processing the refractory gold-sulfide ores and concentrates were worked out. The gold-containing refractory sulfide ores of chalcopyrite, pyrite, barite-polymetallic, quartzites, copper-zinc, antimonite were used in the research. As a result of investigation, the optimal
As a mineral processing engineer, you sure know that it is necessary to draw the gold into wire in order to make gold cloth, gold embroidery, or gold filigree work. Just as it is beaten to form leaf for ornamenting pictures, so also can gold be drawn easily. The same is done with silver and tin, and I believe it could also be done with iron, copper, and brass.

liberate the pyrite from the gangue allowing a low mass pyritic concentrate to be produced by a process such as flotation. However, direct leaching of the concentrate results in poor gold extractions as the cyanide lixivant is unable to contact the gold locked or included within the pyrite (Figure 1). Figure 1 Pyrite Locked Gold Within an Ore
This solution was produced by cyanide leaching of a pyritic gold concentrate (62 g/t) containing high levels of silver (110 g/t) (3 g/L NaCN, pH 10.5-11, %35 w/w, 20°C, 24 h and 10 L).
Nov 17, 1998· Provided is a method for processing a gold-bearing sulfide ore which involves maintaining the ore in a substantially oxygen free environment, preferably beginning with comminution of the ore and ending when a desired final concentrate, enriched in .
