gold occurs as tiny inclusions or submicroscopic gold and are therefore refractory. Silver-rich ores and copper sulfide ores: Silver-rich ores and copper sulfide ores are often free-milling, but when the silver grade is high (>10 g/t) and/or the gold is present as electrum, the processing may need to be modified. The greater reactivity of silver
