According to summarized results, optimum copper and gold leaching parameters are presented in Table 2. Table 2. Optimal gold and copper leaching conditions Parameter Copper leaching Laboratory scale Pilot scale Gold leaching Acid conc.
Treatment of ore is site specific as determined by metallurgical tests. Bench scale metallurgical testing of ores for their amenability to vat leaching is similar to that for heap leaching. First, bottle roll tests of finely ground material are run to determine the ultimate recovery of gold, and for any preg robbing characteristics of the ore.
The present study has been done for the recovery of gold and silver contained in pregnant solution from the cyanidation process using the electrocoagulation technology with iron electrodes; that is a developed alternative technology for the Merril Crowe process.
The flotation of gold bearing ores is classified according to ore type (i.e., gold ore, gold copper ore, gold antimony ores, etc.), because the flotation methods used for the recovery of gold from different ores is vastly different. Get Price new reagent high recovery gold ore leaching tank

gold flotation cell for gold recovery . Separation efficiency improvement of a low grade copper gold . copper concentrate is encouraged to achieve a higher total gold recovery . flotation cells and enable the efficient use of froth washing to improve gangue. Contact Supplier
the reduction of copper in mill feed generally increases gold recovery and decreases processing costs. Where the copper and gold is to be recovered by flotation the overall recovery of coarse and free gold is increased and the treatment charges and payment terms are improved by selling gold dore rather than concentrate.
Treatment of a Polysulphide Ore by Ammoniacal Thiosulfate Solutions and Ion Flotation for Gold Recovery 83 In the last years, resin adsorption has become the most promosing technique for gold recovery. However, its high cost of enforcement and regeneration does not allow engineers to consider it as a practical way of gold recovery.
