mining areas where the company has units operating successfully are gold, platinum, diamonds, chromites and uranium to name but a few. despite lightnin africas relatively short involvement in this market, it already boasts a thickener installation list exceeding forty successfully commissioned units.
thickener are used for tailing or concentrate dewatering . thickeners are used for dewatering slurries of either tailings or product. a thickener is a large circular tank that is used to settle out the solid material from the water in the feed slurry.it is widely used for dealing with slime, wastewater, waste residue in metallurgy, mine, coal, petrochemical industry, building materials
the slurry 1 of ground ore and lime moves into a series of six leach tanks 2 where a sodium cyanide solution is added. the tanks provide sufficient retention time to allow the gold and silver to be dissolved by the cyanide solution. oxygen is added to assist in this process. the slurry then moves through a series of carbon adsorption tanks 3 .
a process for thickening gold ore slurries or slimes for gold purification which comprises adding to such gold ore slimes an effective amount of flocculant comprising a terpolymer containing 5-35 mole % 2-amps, 5-45 mole % sodium acrylate and 50-90 mole % acrylamide, said terpolymer having an rsv of at least 20.
thickeners mining. gold cyanide process. gold cyanide process is an efficient design of extracting and recovering gold from its ore. by cyaniding and carbon leaching crushed gold ore slurry simultaneously, cil process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%. more solutions.
alibaba.com offers 345 slurry thickener products. about 32% of these are mining thickener. a wide variety of slurry thickener options are available to you,
the conventional thickener. historically thickeners were introduced to the mining industry in 1905 when the beneficiation of ores by froth flotation was invented in australia. lifting height of the raking arms depends largely on the application and can vary from 30 cm for feeds with a steady slurry inflow up to 120 cm for thickeners
unlike conventional thickeners, high rate thickeners must use flocculants. the basic design of a high rate thickener is below. high rate thickener feed wells are designed to disperse flocculants thoroughly into the feed end to admit the flocculated slurry into the settling zone of the thickener without destruction of the newly formed floccules.
what is the purpose of thickener in gold mining. thickeners mining technology xsm. the gold bearing slurry is pumped into a sluice box, which collects gold particles, while mine tailings flow into either an abandoned mining pit or adjacent forest. more detailed.
