  • Gold extraction with poly(diallylamine) resins ScienceDirect

    01/12/1988· The maximum gold capacities obtained, about 5 mmol/g (1 g/g) at high gold concentrations (> 1 g/l,), would indicate that two basic nitrogens are needed to complex each gold arfiorL but the structure of the complex and the mechanism of gold absorption is not known. The full resin capacity for Sirorez Au is obtained over the range from pit 11 to less than zero and is similar in cyanide solutions
