chemical characteristics of ore minerals

Minerals Free Full-Text Chemical Characteristics of ...

The composition of the parental magmas of Cu–Ni deposits is crucial for the elucidation of their genesis. In order to estimate the role of magma in ore formation, it is necessary to compare the compositions of silicate rock intrusions with different mineralization patterns, as observed in the Norilsk region. The rock geochemistry of two massifs located in the same Devonian carbonate

Ores and Minerals - Introduction, Extraction ...

Minerals are naturally occurring, homogeneous inorganic solid substances having a definite chemical composition and characteristic crystalline structure, color and hardness. For example, copper pyrite (CuFeS 2), calamine (ZnCO 3) etc. are minerals. A mineral from which metal can be economically extracted in a maximum amount is called an ore.

Mineral Series. A number of minerals contain a varying amount of two or more elements. For example, the mineral Aurichalcite, which has a chemical formula of (Zn,Cu) 5 (CO 3) 2 (OH) 6 contains an unspecific varying amount of zinc (Zn) and copper (Cu). This is indicated by comma separating the Zn from the Cu.
