Extraction from Dolomite and Magnesite Ore. Electrochemical processes are used to extract the metal from dolomite and magnesite ore. When dolomite is crushed, roasted and mixed with seawater in large tanks, magnesium hydroxide settles to the bottom. Heating, mixing in coke, and reacting with chlorine, then produces molten magnesium chloride.

Tenke Fungurume mines copper-cobalt oxide ores by open-pit mining techniques. Drill and blast is employed in the both the ore and waste rock. Conventional loaders and trucks transport the ore to the crusher or stockpiles and the waste to dumps. Larger mining equipment is currently being introduced to enable increased mining rates.

MINING AND CONCENTRATING : Both dolomite and magnesite are hauled out and concerted by conservative methods. Carnallite is hauled out as ore or alienated from other salt amalgams that are brought to the exterior by solution mining. Naturally happening magnesium including brines are determined in large ponds by solar desertion.
