Mopani Copper Mines mineralisation occur within the ore shale. Copper mineralisation in the deposits changes from mostly chalcopyrite in the South Orebody, to chalcopyrite-bornite in the Central area and to bornite-chalcopyrite at Mindola. Cobalt occurs as carrollite and cobaltiferous pyrite in approximately equal proportions. The mine produces copper and cobalt from three sources: Mindola Shaft, Central Shaft and South Orebody Shaft. Vertical crater retreat is the predominant mining method while sublevel open-stopping and sublevel caving methods are also used. In April 2011 Mopani announced its intentions to sink a new $295 million shaft at Mufulira, this should extend the life of the mine
Ore dock ore, in raw or taconite form. Ore docks are typically long, high structures, with a railway track or tracks along the top and a number of "pockets" into which ore is unloaded from railcars, typically by gravity. Each pocket has a chute that can be lowered to discharge the ore into the hold of a ship berthed alongside. The use of pockets and chutes allows the dock itself to be loaded with ore before it is transferred into the freighter. The docks' storage bins or pockets typically are wider at the top than the bottom, and they lead to movable
