CN100485059C Method for recovering gold from sulphide

The invention relates to a method for recovering gold from a sulphidic concentrate, particularly one containing arsenopyrite and/or pyrite, hydro- metallurgically. The concentrate is first subjected to leaching with a concentrated solution of alkali chloride and copper (II) chloride, by means of which the copper minerals and some of the gold in the concentrate are made to dissolve.

Oct 15, 2016 As for dissolving the gold that is not what I want, I want to dissolve the pyrite to get the free gold out. The idea of cooking it for a while sounds interesting but I don't think 400 degrees would be adequate, but its worth a try because it's not a large enough quantities to spend a great deal of money on, maybe a penny weight of gold.

How to Separate Gold from Pyrite

How to Separate Gold from Pyrite

So far no account has been taken of the loss of gold which is contained in pyrites, as it has been assumed that these are saved by concentration if they are valuable, and this subject is dealt with in earlier. Nevertheless, as this gold comes under the head of non-amalgamable gold, its physical state and the causes of its disinclination to unite with mercury may conveniently be considered here

H.A. Ngamreiwung A: It’s true that pyrite from gold mines will contain a small amount of gold. It is microscopic and is found inside the pyrite crystal. Miners who process gold ores will get free gold particles that can be melted into bars, but they also recover pyrite that has small amounts of gold

The other parameter that SGS experts consider when designing refractory gold treatments is whether or not to preconcentrate the gold-bearing ore. This is usually done by flotation of arsenopyrite, pyrite, or other gold-bearing sulfides. To be economically justifiable, preconcentration should meet two objectives.
