WebHematite is virtually free of contaminants, and is easily mined from a nearly inexhaustible source. Additionally, hematite has three main advantages over barite: (1) higher specific gravity; (2) better particle distribution; and (3) a low particle attrition rate. WebTypically, hematite is mined by open pit mining. Overburden is removed, then the ore is mined from an ever-deepening hole. The mineral and rock is first stripped by blasting the rock with explosives and removing it with enormous trucks with capacities over 150 tons.
