本文介绍了采用非氰化浸出－特种树脂吸附湿法新工艺从硫酸浇渣中回收金的工业实践结果。采用简单设备，在矿浆浓度６０％、温度６０℃、（Ｈ２ＳＯ４）为１ｍｏｌ／Ｌ、（ＮａＣｌ）为２５ｇ／Ｌ、（ＮａＣｌＯ３）为５ｇ／Ｌ、Ｅｈ保持在６００～７００ｍＶ条件下进行搅拌浸出、用Ｒ４１０特种树脂进行吸附．饱和树脂用Ｈ２ＳＯ４溶液（０．１ｍｏｌ／Ｌ）洗涤、酸性硫脲溶液解吸，电解沉积Ａｕ，所得Ａｕ粉纯度＞９９％，Ａｕ的总回收率达９４％。该工艺流程短、金回收率高、无污染，经济效益和社会效益显著，具广泛推广应用价值。
This paper describes the industrial practice of non-cyanide leaching - special resin adsorption wet-process recovery of gold from the slag slag. Using simple equipment, the concentration of ore was 60%, temperature was 60 ℃, H2SO4 was 1mol / L, NaCl was 25g / L, NaClO3 was 5g / L, Eh was kept at 600 ~ 700mV, Adsorption with R410 specialty resin. The saturated resin was washed with H2SO4 solution (0.1mol / L). The acid thiourea solution was desorbed and Au was electrolytically deposited. The purity of Au powder was over 99% and the total recovery of Au was 94%. The process is short, gold recovery rate, pollution-free, economic and social benefits significantly, with a wide range of applications.
