Chromite is found in large quantities that is available for commercial mining The chromite minerals are found in 2 main deposits, which are stratiform deposits and podiform deposits Stratiform deposits in layered intrusions are the main source of chromite resources and are seen in countries such as South Africa, Canada, Finland, and Madagascar.
Faces show complex growth and some vertices are truncated by opposite tetrahedron fac They are accompanied by groups of sphalerite crystals, complex forms, easily distinguished by its grayish dull sheen Highlight the intense orange fluorescence of this sphalerite probably due to the presence of cadmium in its crystal lattice.
Monazite, phosphate mineral, cerium and lanthanum phosphate, (Ce, La)PO4, that is the major commercial source of cerium Occurring as small, brown, resinous, rather heavy crystals in granitic and gneissic rocks and their detritus (called monazite sands), monazite frequently contains 10-12 percent.

Zinc is the 23rd most abundant element in Earth’s crust Of the few economically important zinc minerals, sphalerite, a zinc sulfide often with iron in it, is the principal zinc-bearing mineral in most global zinc ore production Sphalerite often contains trace elements that substitute for zinc atoms in the mineral’s crystal lattice.
Chile The top producers of copper are found throughout the world The number one producer is Chile, a South American country Chile produces 5,750,000 tons of copper annually The country attracted foreign private investments in the 90's when the government passed a mining law that compensation regulations for the case of mine nationalisation.

List of Ores of Metals and Producing States By GK Planet Team Wednesday, 23 December An ore is a type of rock that contains sufficient minerals with important elements including metals that can be economically extracted from the rock.
Zinc-to-cadmium ratios in typical zinc ores range from 200:1 to 400:1 Sphalerite (ZnS), the most economically significant zinc mineral, commonly contains minor amounts of other elements; cadmium, which shares certain similar chemical properties with zinc, will often substitute for zinc in the sphalerite.

Sphalerite (zinc sulfide) is the primary ore mineral from which most of the world's zinc is produced, but a number of other minerals that do not contain sulfide contain zinc as a major component Much of the early zinc production was from nonsulfide deposits; however, as these resources were exhausted, production shifted to sulfide deposits.
Aug 10, Zinc is the 24 th most abundant element in the Earth’s crust It is commonly found in association with copper and lead in various or The main zinc ore mineral is called sphalerite, which is a zinc sulphide Sphalerite is also known as zinc blende and contains 67% zinc when pure It is commonly associated with galena, a lead sulphide mineral.
