Gold processing, preparation of the ore for use in various products. Native gold is the most common mineral of gold, accounting for about 80 percent of the metal in the Earth''s crust. It occasionally is found as nuggets as large as 12 millimetres (0.5 inch) in diameter, and on rare occasions
Jan 24, 2014· Just because a web page mentions it, that does not mean flotation of free gold is a commercially viable process There are loads of gold mines all across the world.
However, sometimes the ore we are using also has other sulphides present in it as impurities. For example, lead sulphide generally has zinc sulphide also present as impurity which will also float in the froth floatation process along with the lead sulphide. To make sure that lead sulphide floats but zinc sulphide do not float, we add depressants.
