本文第一部分叙述氰化介质的特性及对提金树脂的要求,离子交换树脂吸附金的一般原理,各种离子交换树脂的特性并着重描述含强碱基团的弱碱性树脂即双官能团树脂的特性,提金树脂吸附杂质的行为。第二部分主要叙述荷载金树脂的解吸过程:如弱碱性树脂的解吸,强碱性树脂及含强碱基团的弱碱性树脂三种解吸方案:锌氰络合物解吸方案;酸性硫脲解吸方案及硫氰酸铵解吸方案。
The first part of this paper describes the characteristics of cyanide media and the requirements of the gold extraction resin, the general principle of the ion exchange resin adsorption of gold, the characteristics of a variety of ion exchange resins and focuses on weak base with strong base groups that the bifunctional resin The characteristics of the gold resin adsorption of impurities behavior. The second part mainly describes the desorption process of loaded gold resin: desorption of weakly basic resin, three kinds of desorption schemes of strong basic resin and weakly basic resin with strong basic groups: desorption scheme of zinc cyanide complex; Urea desorption scheme and ammonium thiocyanate desorption scheme.
