About 57% of these are waste management, 10% are other recycling products, and 8% are vibrating screen. A wide variety of gold recovery from electronic waste options are available to you, such as free samples.
Three different solvent extraction systems for the recovery of gold from alkaline cyanide solutions are reviewed. These include the modified amine extractants in which the basicity of simple alkyl amines, with respect to the aurocyanide anion, is controlled by the addition of alkyl phosphorous esters. The selectivity of such modified amines for gold extraction from alkaline cyanide solutions ...
