blanket g mine caledonia mining corporation plcthe ore shoots vary in shape from the tabular to lensoidal quartz reefs to the massive to pipelike disseminated sulphide reefs (dsr). g mineralisation occurred as a result of the reaction between rising hot fluids and the iron rich minerals in the shear zones.g processing mining and concentrating britannicag processing g processing mining and concentrating the nature of the ore deposit determines the mining and mineral processing techniques applied. oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. in this case they are merely shattered by explosives and then piled into heaps forg extraction this is typical of lowgrade, oxide deposits. normally, the ore is crushed and agglomerated prior to heap leaching. high grade ores and ores resistant to cyanide leaching at coarse particle sizes, require further processing in order to recover the g values. the processing techniques can include grinding, concentration, roasting, and pressure
radioactive waste from uranium mining and milling us epaaug 09, · the ore is brought to a mill, crushed, and ground up before chemicals are added to dissolve the uranium. the uranium is then separated from the chemical solution, solidified, dried and packaged. heap leaching this process uses a liquid to dissolve a chemical. similar to the way pouring hot water over crushed coffee beans leaves coffee groundsuranium mining overview world nuclear associationmill chemistry. the crushed and ground ore, or the underground ore in the case of isl mining, is leached with sulfuric acid uo 3 + 2h + ====> uo 2 2+ + h 2 o uo 2 2+ + 3so 4 2====> uo 2 (so 4) 3 4. the uo 2 is oxidised to uo 3.. with some ores, carbonate leaching is used to form a soluble uranyl tricarbonate ion uo 2 (co 3) 3 4.this can then be precipitated with an alkali, e.g. as sodiumheap leaching heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and reseparate them after their division from other earth materials. similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the
