gold ore thickener plant Djibouti

PROCESS FLOWSHEET DESCRIPTION Continuous countercurrent decantation cyanidation flowsheet ORE TREATED Gold and silver ores amenable to the cyanidation process and where economics justify plant outlay ADVANTAGES By producing the precious metals in bullion form the highest net return is realized on many gold and silver ores Where the tonnage available for treatment justifies the capital

Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids The early methods of thickening employed plain flatbottomed tanks into which the pulp was fed until the tank was full The solids were then allowed to settle as long as required the top liquid was decanted the settled solids were

The customer Carpentaria Gold Pty Ltd Ravenswood Operation is located approximately 95km southwest of Townsville in northeast Queensland The processing plant processes 15 million tons per annum of high grade underground ore using single stage crushing SAG semiautogenous grinding and ball milling and carboninleach processing with a gravity circuit for recovery of free gold

The 5th rock gold processing plant in Tanzania How processing plant configurated and what equipments were used Read more

crushing and grinding of the ore addition of process water generally decanted from the tailings pond to form a slurry addition of lime to the ore and cyanide solution to the slurry to leach the gold and silver into solution addition of carbon to adsorb attach dissolved metals and remove them from the slurry

thickening 612 solids by mass is performed to increase the pulp density to about 50 solids by mass This reduces the size of the leaching plant that would be required as well as reduces the amount of leaching reagents required Many gold plants use conventional thickening with flocculant addition High rate thickeners as well as dewatering

More than 30 kinds of solutions can be chosen for the metal nonmetal and tailings our experts working in the laboratory to research the best solution for mine samples each day Best solution best design best research that could create a best mining project with high profit

The first 12 m diameter rakeless thickener in the Australian gold mining industry was installed to treat plant tailings at the St Ives gold plant in April 2000 The plant processes approximately 32 M tonnes of ore producing about 430 000 oz of gold per annum using conventional crushing grinding gravity and carbon in pulp processing methods

Figure 2 Thickener plant flow sheet Reducing operational variability through control system improvements Despite the design of the thickener and installation of good instrumentation poor overall plant design inadequate automation or low operator focus can be contributing factors in thickeners that fail to consistently achieve the best
