How to Separate Gold from Pyrite
In panning large samples, only one or two specks of gold could be seen, although the ore contained from 1 to 2 ounces per ton. This ore yielded only about 40 per cent, on being amalgamated, but over 90 per cent, was dissolved out by leaching the raw ore with cyanide of potassium, and similar results were obtained by chlorination.
Gold Ore Roasting Techniques
The calcine has an acid reaction, and before it can be handled in contact with iron and steel, it must be neutralized. This is carried out in a preliming step in a 7- by 7-ft. turbo-agitator, which oxidizes the ferrous salts and precipitates the corrosive sulphates and chlorides present as hydrates.
