摘要
对经过焙烧,且钴、铜、镍、钼、铋等有用元素基本已浸出的某含金多金属矿石浸渣,进行了硫脲浸金试验。试验结果表明,当硫脲用量为8kg/t,浓硫酸用量20L/t,浸出时间为4h,金的浸出率达90%以上。
Thiourea leaching of the gold-beating polymetallic ore after wasting and removing some metal elements such as copper, cobalt, nickel, molybdenum and bismuth was explored . The experimental results showed that the gold leaching recovery is more than 90% under conditions of being thiourea consumption 8 kg/t , dense sulphuric acid addition 20 L/t and leaching time for 4 hours .
