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 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 origin of metallic ore deposits at convergent plate boundaries is hy- pothesized to be the result of the partial melting of seawater-saturated rocks of the oceanic lithosphere in a subduction zone. The high heat and pressure that cause the melting also facilitate the release and movement of metals from the partially molten rock.
6. Mineral Deposit versus Orebody A mineral deposit/ore deposit may be defined as a rock body that contains one or more elements (or minerals) sufficiently above the average crustal abundance to have potential economic value. Mineral deposits can be classified into two broad categories: (a)metallic mineral deposits (e.g., deposits of copper, lead, zinc, …

A magmatic deposit is one in which the metal concentration takes place primarily at the same time as the formation and emplacement of the magma. Most of the nickel mined in Canada comes from magmatic deposits such as those in Sudbury (Ontario), Thompson (Manitoba) (Figure 20.4), and Voisey's Bay (Labrador). Th…

The major operating metallic ore deposits of Tasmania are (a) volcanic-hosted massive-sulfide deposits at Que River, Rosebery and Hercules (Fe-Zn-Pb-Cu type), Mt. Lyell (Fe-Cu type), and Savage River (Fe oxide type); (b) tin-tungsten deposits in veins at Aberfoyle, Lutwych, Storys Creek, and Mt. Oakleigh; (c) tin deposits of carbonate-replacement type at Renison and …
What are the metallic ore deposits in Montana? Montana has metallic ore deposits that contain minerals such as gold, silver, copper, chalcopyrite, arsenopyrite, pyrite, pyrrhotite, magnetite, and accessory minerals like Bi-sulfides and Bi-Ag-tellurides.
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 ...
