Technological Research on Comprehensive Recovery of a Copper- gold Ore in Inner Mongol
摘要
Abstract
An experimental research on comprehensive recovery was carried out to make full use of such valuable elements as copper, lead, zinc and sulfur, which were contained in a gold ore in Inner Mongol. The technological flowsheet of recovering coarse gold with Knelson Concentrator-flotation separation-concentrate regrinding-gold leachint was adopted, among which CFS and lime were acted as high - efficiency inhibitor of pyrite when flotation separation was performed. Through the stage grinding,the copper concentrate of 21.87％ Cu with a recovery of 90.27％and the sulfur concentrate of 44.33％ S with a recovery of 85.76％ 91.11％ were obtained respectively. As well as the comprehensive recovery of gold reached 91.11％. All of these separation indexes are satisfactory. Meanwhile,this technology is economic and reasonable, suiting for industrial production.关键词
