Gold Electrowinning from Cyanide Solutions Using Three

2017-8-11  Work is devoted to studying electrowinning of precious metals, in particular gold, in rich cyanide solutions on three-dimensional cathodes of electronegative metals. The object studied is production solution obtained during cyanide leaching of gravitation concentrates containing about 95 g/m3 of gold, 30 g/m3 of silver, and 6.5 g/dm3 CN–.
