Thiosulfate leaching of silver, gold and bismuth from a ...
Apr 01, 2005· The selective leaching of a bismuth from the lead concentrate (Atacocha, Peru) by using of sodium thiosulfate and mechanical activation as the pretreatment step was examined as the last example. It is possible to achieve more than 90% recovery of a bismuth in leachate even in three minutes for mechanically activated samples.

Rebellious Ores: Sulfides, Selenides and Tellurides
It is extremely important when treating high sulfide ores with cyanide to keep a sufficient protective base in the solution. Many sulfide minerals also contain things like copper or antimony that can react with the cyanide, preventing the cyanide from leaching out the gold and silver.

The Republic of Kazakhstan
At the cyanide leaching of preliminary oxidized sulfide ores, the process of gold solution is expressed with the equation: 4 А u + 8NaCN + 2H 2 O + O 2 = 4Na[Au(CN) 2 ] + 4NaOH. As a result of side reactions, the part of active groups of sorbent is occupied with anions of admixtures that reduces the sorbent capacity with regard to noble metals.

Barrick Thiosulfate Leaching of Double Refractory Ore
the Leaching Team to optimize the thiosulfate leaching process for double refractory ores. In addition, the Leaching Team analyzed the thiosulfate leaching process compared to the traditional cyanide process. They found that the profit of the thiosulfate leaching process was similar to that of the traditional cyanide method.
