This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction/electrowinning). Advantages of these processes are: Much less energy is used than in traditional mining.

The hot potassium carbonate process has been used effectively in many ammonia, natural gas, hydrogen, direct iron ore reduction, and ethylene oxide plants for many decades (Chapel et al., 1999). German patents using hot carbonate absorption of CO 2 can be found from as early as 1904 ( Kohl and Riesenfeld, 1985 ).
Blast furnaces operate on the principle of chemical reduction whereby carbon monoxide, having a stronger affinity for the oxygen in iron ore than iron does, reduces the iron to its elemental form. Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and ...
