What is Mineral Processing? (with pictures)

Early mineral processing typically involved manual labor, such as striking ore with hammers to break it open. This process of separating minerals from ore by hand was known as spalling. Similar processes were developed during the 10th century that mechanized the use of hammers to break the ore.
