Mining from Ore to Metal
Rock And Minerals
Mineral is a homogeneous inorganic substance that occurs naturally, usually in
crystalline form with a definite
chemical composition.
The common rock-forming minerals (RFM)
are
quartz, orthoclase feldspar (KAlSi3O8), plagioclase feldspar (CaNaAlSi3O8), albite,
mica group such as muscovite and biotite.
The common ore-forming minerals (OFM)
are
hematite (Fe2O3), cassiterite (SnO2), chalcopyrite (CuFeS2), sphalerite (ZnS),
galena (PbS), baryte, gypsum (CaSO4), apatite, etc.
Rock
is an assemblage of mineral(s) formed under natural process of igneous, sedimentary and metamorphic origin. The
common rocks are basalt, granite, quartzite,
