1.3 Run-Of-Mine Material and Minerals. Generally, mineral processing begins when an ore is delivered from a mine, to a processing facility. At this point, the ore is called run-of-mine material because there has been no treatment performed on it. There are three primary types of run-of-mine materials: Run-of-mine consisting of useful materials.
