A ore (of Latin will undermine mine) is a Roche containing mineral useful in sufficiently interesting proportion to justify the exploitation, and requiring a transformation to be used by the Industrie.
The majority of the metalliferous ores are:
- of the Oxide S (Bauxite);
- of the Sulfide S (Crystal, Sphalerite);
- of the Carbonate S (Malachite, Siderite);
- of the Silicate S (Garnierite).
Industrial civilization uses significant amounts of minerals and Heavy metals. In consequence of an increasing demand out of metals and other mineral resources, the ores are exploited with increasingly low contents. The risk of exhaustion of these Natural resources is in particular related to the wasting of these same resources, often dispersed after use, rather than to be recycled. Moreover, in many applications, the absence of recovery is associated with a diffuse Pollution of the Environnement by very toxic products. The world prospects indicate that for many elements (such as the money, the Fluor, the tin, the Zinc, the Nickel) the current reserves will only make it possible to cover two to three decades of exploitation. It is however allowed to think that the duration of the reserves available would be prolonged by the systematic installation of the Recyclage.
