Tank leaching is a process used in the extraction of valuable metals from ores where the ore is placed in a tank and a leaching solution is added to dissolve the desired minerals This method allows for better control over the leaching conditions such as temperature pH and concentration of reagents enhancing recovery rates and minimizing environmental impact Tank leaching is
·Intensive cyanidation is proven technology that gives high recoveries from gravity gold concentrates this was achieved by either a high speed agitator in a tank or by vat leaching Both methods had their problems due either to excessive wear and high energy requirement for the agitated systems or channelling of solution and loss of fine
·In the leaching circuit the ore slurry commonly referred to as pulp is then subjected to leaching in a series of sequential agitated cyanidation tanks to which cyanide is added and air is sparged into to enable gold leaching Adams 1989 Once solubilized gold adsorption occurs in a separate series of agitated tanks in the case of
3 ·1 After the crushing and grinding stage add 9 step arranged high efficiency cyanidation leaching tanks into the pulp Gold pulp cyanidation is carried on the first two leaching tanks countercurrent adsorption operation is carried on the last six or seven leaching tanks cyanidation and adding activated carbon simultaneously
·stirred tanks The thiosulphate process offers advantages over cyanide leaching in the following situations • Thiosulphate leaching yields similar gold recovery as cyanide in some cases while in cases such as preg robbing ores naturally occurring carbonaceous material that preferentially absorbs the gold cyanide complex but not the gold
·Keywords Gravity concentration leaching small scale mining Sluice box 1 Introduction Small scale gold mines are the mines that use relatively small and low quality devices to extract ore containing gold from the earth s crust This mine is currently operated by both licensed trained
Thiourea leaching of gold despite first being reported in 1941 [] has never been clearly established into a few industrial applications were reported between 1984 and 1992 [] although more recently Birloaga et al [] report on the development of a pilot plant part of the FENIX project consists of two hydrometallurgical technologies of which GOLD REC 1
