ORE PROCESSING The onsite mill processes up to 3,500 tons of ore daily. Gold is recovered using several unit operations. Once the ore is delivered to the mill, the grinding circuit reduces the ore to a very fine particle size (about half of the size of a grain of table salt). This is the first step in separating the gold from the rest of the rock.
