The geochemistry of the major ingredients is a precise translation of the mineral composition. The constituents that exist only in the francolite structure are P 2 O 5 and F. In average, the F/P 2 O 5 ratio in the Egyptian phosphorites is about 1.12. According to McConnell (), the introduction of F into the apatite structure has several important consequences where it …

The disseminated mineral deposit is a geological body, and mostly consists of metallic ore mineral in low concentrations. Many of these deposits contain very low ore grades, measuring just about a few ounces per ton, and these ore minerals are not visible to the naked eye. Although the concentrations are low, the deposits are profitable enough ...
The terms ore mineral and mineral deposit were originally applied only to minerals and deposits from which metals are recovered, but present usage includes a few nonmetallic minerals, such as barite and fluorite, that are found …
Major metallic ore deposits of Ethiopia consist of precious metals (Au, Pt), rare metals (Ta) and to a lesser extent Ni and Fe; some deposits are currently mined for Au and Ta (e.g. Lega Dembi, Kenticha) or are at an advanced stage of investigation (e.g. Bikilal project, Fe); to date, base metals (Zn, Pb, Cu) and alloy metals (Cr, Mo, Mn) are ...
If the conduit is used by the ore-bearing fluid before entirely closing, the ore-bearing fluid would rapidly upwell in large-scale, and produces the giant ore deposits.
Most metallic ore deposits are currently exploited in relatively low grade metamorphic zones, leaving large areas of Québec underdeveloped by the mining industry. Exploration in metamorphic ...
