Gold | Minerals Education Coalition
Gold is so valuable that it is worth the effort to recover even minute amounts from copper and silver ore. It is estimated that the total amount of gold yet to be removed from the Earth is 100,000 tons.

Gold mineral processing
Treatment of refractory gold ore (whole ore and flotation concentrates) has become more prominent since the 1980s, with many gold discoveries often including ores that are wholly or partially refractory. Refractory pre-treatment processes include pressure oxidation, biological oxidation and various forms of roasting. Design teams familiar with all three pretreatment processes can maximize a ...
