| Abstract: | to treat gold flotation concentrate of 45.33g/t in grade by the technology of thiourea leaching accompanied with carbon adsorption under the circumstance of heightening pulp temperature properly, the gold leaching rate real-ched to 94.26% and the thiourea consumption reduced to 6kg/t while the total gold recovery came to 90.28%. Factors, such as heightening pulp temperature properly and adding oxidant, protective agent and absorbent in proper amount, are the key points to raise leaching rate and reduce thiourea consumption. |
