离子交换树脂吸附提取矿浆中的金有明显的优点,即树脂具有高的吸附容量和机械强度,并且可以多次使用。为此,我院已研制出了提金用的353E树脂,且已决定用该树脂回收涞源金矿中的金,但对353E树脂的选择性以及吸附液pH的影响尚未作系统的研究。为了进一步了解353E树脂的性能,本文对该树脂的选择性以及吸附金和银的性能进行了系统的研究,同时还研究了吸附贱金属的性能。
Ion exchange resin adsorption extraction of gold in the pulp has the obvious advantage that the resin has high adsorption capacity and mechanical strength, and can be used many times. To this end, our institute has developed 353E resin for gold extraction, and has decided to use this resin to recover the gold in Jueyuan Gold Mine. However, the effect of 353E resin selectivity and the pH of adsorption solution has not been studied systematically. In order to further understand the properties of 353E resin, this paper systematically studied the selectivity of the resin and the properties of adsorbed gold and silver, and also studied the adsorption of base metal properties.
