Process for treating goldcontaining sulfide ores

Feb 24, 1997 A process for treating a granular sulfide ore containing gold and at least one accompanying metal other than gold, said accompanying metal being iron or a non-ferrous metal selected from the group consisting of silver, copper, nickel and zinc, which comprises the steps of a calcining the granular sulfide ore at a temperature of 500 to 900 ...

Process for treating goldcontaining sulfide ores

The present invention is a process to recover precious metals from sulfide ores. It involves chlorinating a mixture of an ore concentrate and salt to form a liquid melt. The salt preferably contains potassium chloride. This chlorination is carried out at a temperature between 300 and 600 C. while stirring. The process converts precious metals in the elemental and sulfide forms into ...

Process to Recover Gold from Sulfide Ores GOLD

Sulfide Ore an overview ScienceDirect Topics

For sulfide ore processing, nickel has to be separated from the iron present in the sulfide concentrate. This is conventionally done in both the smelting and converting stages. To aid iron rejection in the smelting stage, the concentrate is first partially roasted to oxidize the iron sulfide.

Jul 12, 2019 the flotation process is commonly used to process the gold-bearing quartz vein ore which contains fine particle gold and good flotability sulfide ore, and process gold sulfide ore which contains several valuable metals such as copper, lead, zinc.

ALACER GOLD TO PURSUE POX AS SULFIDE ORE

pler Sulfide Ore Characteristics In order to understand why POX is the best processing solution at pler, it is important to appreciate the key characteristics of the refractory sulfide ore present at pler. The highly refractory nature of the pler sulfide ore means that poor gold

Apr 24, 2017 This was the first commercial method used for gold extraction. Place the ore into the mortar and grind it to the size of sand grains. Put the ore grains into a plastic bowl. Add the 35-percent hydrochloric acid to the sodium hypochlorite bleach into a flask or beaker, in a two-to-one ratio of acid to bleach. Ensure that the liquid mixture is at ...
