gold ore carbonate

The Alamoutala Carbonate, The Alamoutala gold deposit is located in the Kédougou-Kénieba inlier, a window of Paleoproterozoic rocks that crop out in eastern Senegal and western Mali The deposit is part of the ~3-Moz Au Yatela district and produced 308,400 oz Au between 2002 and 2012Arizona's Placer Gold Deposits by County, Drilling later revealed considerable ore on other properti Experiments to leach and recover copper from the carbonate ore were started in 1912 and were concluded successfully in 1915 By 1917 a 5,000-ton leaching plant was built, permitting large-scale exploitation of the carbonate orOre genesis, Ore deposits formed by lateral secretion are formed by metamorphic reactions during shearing, which liberate mineral constituents such as quartz, sulfides, gold, carbonates, and oxides from deforming rocks, and focus these constituents into zones of reduced pressure or dilation such as faults This may occur without much hydrothermal fluid flow ,What is Gold Ore worth? High Grade Mining Ore, That would make the gold in a one pound ore sample worth approximately 75 cents, and this is assuming that the ore is extremely rich Many mines can run profitably on much lower grade ores, which might easily reduce the average value of ore down to 25 cents or less per poundGenetic Model of Ore Deposits ~ Mining Geology, May 18, 2015· 2- Gold-Rich Types: are of two general types: 1) Archean iron formation types, and 2) quartz-carbonate veins Archean Iron Formation Types : Occur mostly in Precambrian shield areas Vein morphology but most veins apparently concentrated in peculiar iron-rich shales and sandstones which are upgraded by at least one and usually several ,.
