·Gold Sludge Production Carbon Desorption and Electrowinning Facilities Elution CN or OH dissolved in desorption solution is easier than Au CN 2 to be absorbed by the activated carbon which causes Au CN 2 absorbed on loaded carbon is replace by CN or OH and the reversible balance of of gold adsorption is broken
·The experiment was continued until the gold concentration in the eluate was less than 20 mg/l 364 Conradie et al / Hydrometallurgy 37 1995 349 366 Table 9 Results of the elution experiment with simultaneous electrowinning using a stainless steel mesh cell Duration h Elution efficiency % 100 Average extraction efficiency % 23
In gold electrowinning process when the electrolysis equipment is added with anions which are more easily absorbed by activated carbons Au（CN）2ˉ is replaced by anion and the gold desorption is achieved After the carbons loaded with gold are desorbed pregnant solution is process via ionization At last solid gold is attained
·05 Gold ore electrowinning processes and equipment The eluted gold containing solution passes through the electrolytic cell In the electrolytic cell gold ions are reduced to gold metal and deposited as a gold layer on the electrode Electrowinning cells are used to recover gold from the eluate obtained during the elution process
·Gold ore CIP process is a well established gold extraction method that is widely adopted due to its high efficiency and relatively low operating costs The conditions of this process operation and equipment selection are determined according to ore characteristics processing scale and economic considerations
·Below a concentration of mM over 99% of gold was removed within a single extraction pass and above mM 81% of the ddFc was utilized for the uptake of gold proving ddFc to be a high
No accumulation and loating gold electrowinning equipment was developed by Changchun Gold Research Institute Co Ltd in 1998 and entered the market 1 High gold desorption rate the carbon poor gold grade after desorption is less than or equal to 50g/t the same industry products are generally less than or equal to 100g/t
·Gold electrowinning is commonly performed using steel wool cathodes and punched stainless steel plate anodes General conditions include 2 4 V 100 400 g Au/l input 1 10 g Au/l output 2% NaCN 2% NaOH and 50 90 °C with very low effciencies [ 13 ]
·High Temprature Quick Gold Elution and Electrowinning Machine Elution CN or OH dissolved in desorption solution is easier than Au CN 2 to be absorbed by the activated carbon which causes Au CN 2 absorbed on loaded carbon is replace by CN or OH and the reversible balance of of gold adsorption is broken
·Hydrometallurgical gold recovery processes play a pivotal role in the gold mining industry contributing to more than 90% of global gold production Among the array of techniques available the Merrill Crowe process adsorption ion exchange and solvent extraction are central in extracting gold from leach solutions While the Merrill Crowe process and gold complex
Elution Electrowinning Cell— Relative Equipment Desorption electrolysis system obtains gold mud from carbon by desorption and electrowinning Gold Loaded Carbon Content ≥/t Advantage In the high temperature 150℃ and pressure the desorption rate reaches 98% Since desorption and electrolysis does not require different temperatures it is not
