An ore processing plant, also known as a smeltery, is a facility that processes raw ore into usable products. It typically involves crushing, grinding, and separating the ore into different components, such as metals, minerals, and other materials. The smeltery then refines these components into usable products, such as metals, alloys, and other materials. The ore processing plant is an important part of the mining industry, as it helps to extract valuable resources from the earth.
