ORE DEPOSIT TYPES AND THEIR PRIMARY EXPRESSIONS K.G. McQueen
PRIMARY EXPRESSIONS OF ORE DEPOSITS A well known aspect of ore deposit expression is the association of particular ore types with particular host rock assemblages, i.e., the ore-host rock association (e.g., Stanton, 1972). This association broadly re???ects the geological environment and processes that have formed the ore.

Ore deposits formed by oxidation and supergene enrichment
The effects are therefore: 1) To render barren the upper parts of many ore deposits. 2) To change minerals into more usable or less usable form or to make rich bonanzas. 3) Supergene enrichment may add much where there was little. 4) Leaner parts of the vein may be made rich. 5) Unworkable protore may be enriched to the ore grade.

Manganese Ore Deposits
manganese "manganese deposits" "manganese minerals" "manganese ores" "Mn deposits" Manganese. Manganese is the ninth or tenth most abundant element in the Earth???s crust . Most of its industrial use is in steel making with a much lesser amount going into the production of batteries. It is very similar to iron in its chemical properties.

This caused, for example, formation of the diagenetic-metamorphic skarn rocks in Sweden. Elevated Mn-contents of metamorphic silicates (garnet, pyroxene, stilpnomelane, etc.) conserve the geochemical halos of Sedex ore deposits and are useful prospecting tools. 6. Ores could also be formed from metamorphic fluids.

mn ore deposits ppt
Hydrothermal Manganese Deposits These are deposits typically found as epithermal and mesothermal veins, and rarely as strata bound deposits. The manganese minerals may form ore-grade concentrations, or may be present as gangue in association with ore minerals of other metals, commonly with Pb-Zn-Ag vein mineralization.

Uranium in Minnesota
a substantial quantity of private land in Minnesota has been leased for ex?? ploration and mining, and leases for state-owned land are being considered. Thus Minnesotans, who have been evaluating the potential advantages and disadvantages of copper-nickel mining, may soon have to consider uranium mining and milling as well.
