The dividing point between the two plants lies at the fine ore bin; all equipment prior to this bin is considered in the Crushing Plant and all equipment subsequent to it in the mill General Design Criteria: MillingA primary gyratory crusher is used to reduce dump material from up to 1500mm to below 200mm in size before conveying it to either of two stockpiles Feeders and conveyors transport the ore to a twostage dry crushing plant where two secondary crushersPalabora Mining Company Ltd

What types of plant are found on mining operations?

Plant can range from electric drills, lifts, escalators, tractors, haul trucks, hand trolleys, cranes, commercial fishing nets to arc welding gear Buildings, steel structures and their foundations are also considered to be plant, particularly if they are loadsupporting structuresAfrican gold plant These figures are not a standard but reflect the nature of the ore and the design basis for a particular situation The ore is first reduced in size (typically 80% passing 75µm) to ensure that all nonrefractory gold is readily accessible for cyanide leaching There are several variations of comminution circuits used in theThe process design of gold leaching and carboninpulp
