· Currently, 60% of the world production of 110,000 metric tons (mt) of cobalt is supplied by the Congo. The German Federal Institute for Geosciences and Natural Resources (BGR) expects this value to increase to 70% by 2026. Land-based mines will probably not be able to cover cobalt demands of more than 250,000 mt in 2026.

Phosphorus is an essential element that occurs in the mineral apatite, which is found in trace amounts in common igneous rocks (Figure 13.5.1.15 ). Phosphorite rock, which is formed in sedimentary environments in the ocean [ 50 ], contains abundant apatite and is mined to make fertilizer.

Georgius Agricola, a German physician who was much more enthusiastic about mining than medicine, documented mining practices and mineral descriptions in his book De Re Metallica, published in 1556. The title literally translates as "On the Nature of Metals," but at that time the word "metal" was widely used to describe any material from the earth.

The term bioleaching refers to the conversion of an insoluble metal (usually a metal sulfide, e.g., CuS, NiS, ZnS) into a soluble form (usually the metal sulfate, e.g., CuSO 4, NiSO 4, ZnSO 4 ). As the metal is extracted into water, this process is called bioleaching. Because this process involves oxidation, it may also be termed biooxidation .
