carbon grades use on cil plants

Gold ore CarbonInLeaching (CIL) processing technology SBM The activated carbon is advanced countercurrent to the slurry w by pumping a portion of the slurry upstream with airlifts. A high grade of gold on the carbon and a high gold recovery are obtained by stagewise adsorption and a countercurrent ow. The carbon in the rst CIL tank thus contains the highest grade of gold. 3. Gold CIL &CIP Gold Leaching Process Explained

dynamic simulation of the carbonin pulp and carboninleach the cip and cil processes use granulated activated carbon that is mixed with the pulp, composed of ore and water, and after it has been loaded with aurocyanide ion, the rich activated carbon is pumped out into the adsorption circuit and sent to the elution process. the main difference between the cil and cip processes is that in the g cil ampcip g leaching process explained ccdthe process technology and equipment design are described in detail for the carboninpulp process. a typical process flowsheet is given with a description of appropriate design criteria. technical advantages and disadvantages as compared to the traditional countercurrent decantation process are discussed including some illustrative comparisons of capital and operating costs. see full list on 911metallurgist in the carboninpulp process activated carbon is mixed with a ground ore plus water slurry in which g and silver cyanides are dissolved. after the precious metals are adsorbed onto the carbon, the loaded carbon is separated from the pulp and stripped. the barren pulp is disposed of as tailings and the precious metals are recovered from the strip solution by electrowinning or zinc precipitation. the carboninpulp process is used to treat low grade g and/or silver ores. the ore is first ground in a ball mill which operates in closed circuit with a cyclone or similar sizing device. this is done to produce a feed suitably sized so that subsequent leaching is rapid. the ground ore overflowing the sizing device generally runs at 25 to 35 percent solids. first it is passed through a trash screen to remove tramp oversize, plastics, wood, and other debris. it is then thickened to a requisite 4050 percent solids prior to leaching. this range of pulp density keeps the activated carbon see full list on 911metallurgist the most well known carboninpulp plant remains the prototype homestake plant in lead, south dakota. operating since 1973, this facility treats 2130 tonnes of ore per day averaging 2.7 g g per tonne. homestake has also operated small silver carboninpulp plants at creede and cripple creek, colorado since 1979. duval corporation operates a 2720 tonne per day carboninpulp plant at battle mountain, nevada with an average grade of 2.7 g g and 3.4 g silver per tonne. see full list on 911metallurgist g mining process development
