Ways To Process Gold Ores
Suitable for processing natural gold embedded in coarse particle size, stored in pyrite and other sulfide ores. Different from single flotation is to add mercury plate for gold recovery after grinding, the recovery rate can reach 30-45%. After mercury amalgamation, the slurry is flotation through the overflow of the classifier.

Thiosulphate as an alternative to cyanide for gold processing – issues
Thiosulphate is an attractive alternative reagent to cyanide for processing gold ores. It is relatively cheap and non-toxic, forms relatively strong gold and silver complexes, and readily leaches gold ores in ammoniacal solutions, catalysed by Cu(II). It is particularly suited to carbonaceous ores where the recovery of gold by cyanide is poor.
