The ore now goes through a three-stage processing cycle to ensure the gold is economically recovered from the ore. Stage 1: Crushing and Grinding Ore stockpiled from underground and open pit mines is fed into the primary crusher at the process plant. The jaws inside crush the rock down to fit through the 125mm gap at the bottom.

Before being smelted, low-grade concentrates from complex ores are first roasted in a reverberatory or multiple-hearth furnace at temperatures between 550 and 650 C (1,025 and 1,200 F) to drive off the sulfur. Depending on the type and quantity of impurities, oxidizing, reducing, or chlorinating reactions take place.

Iron ore is a rock or mineral from which metallic iron can be extracted economically. It constitutes 5% of the earth's crust. Viable forms of ore contain between 25% and 60% iron. Ore greater than 60% iron is known as natural ore or direct shipping ore, meaning it can be fed directly into iron-making blast furnaces.
