本文概述了硫脲法自硫化矿和氧化矿中提金时,主要因素对金浸取及氧化还原混合电位的影响,以及加入 SO_2、H_2SO_3或 Fe°还原剂对金的浸取和硫脲转化的影响。对硫脲的损耗亦进行了研究。当矿石中含有游离碳时,硫脲铁在浆浸取法将是高金浸取率及低硫脲消耗的唯一可行方法。
In this paper, the effects of the main factors on the gold leaching and the redox potential were studied when the thiourea was extracted from the sulphide ore and the oxide ore. The leaching of gold and the thiourea conversion by the addition of SO 2, H 2 SO 3 or Fe ° reducing agent Impact. Thiourea loss has also been studied. When the ore contains free carbon, the leaching solution of thiourea in pulp will be the only viable method for high gold leaching and low thiourea consumption.
