    Processing. Ball Mill Ore processing separating the valuable minerals (such as gold) from the rocks takes place in the mill facilities, usually as close as possible to the mining site to reduce hauling costs. While there are many ways to process different kinds of ore, generally the mill starts by grinding ore into a powder.
