[英刊《矿物工程》报道]加拿大资源利用研究所和加拿大魁北克拉瓦勒大学采矿和冶金系等单位,对用硫脲从黄铜矿精矿中萃取金的问题进行了初步技术-经济评价。含金黄铜矿的传统处理方法是冶炼。然而,铜精矿生产厂必须为处理精矿中的杂质而付出代价(铋、碲和砷)。在冶炼中这些杂质被带到阳极上,因而会引起电解精炼中的问题。9年前,黄铜矿处理厂曾考虑研究出一种替代冶炼技 [British Journal “Mineral Engineering”] Canadian Institute of Resource Utilization and University of Quebec Laval University, Department of Mining and Metallurgy and other units, the use of thiourea from chalcopyrite concentrates extracted gold preliminary technical - economic evaluation . The traditional treatment of gold-bearing chalcopyrite is smelting. However, copper concentrates producers have to pay for the impurities in the concentrate (bismuth, tellurium and arsenic). These impurities are brought to the anode during smelting and thus cause problems in electrolytic refining. 9 years ago, the chalcopyrite processing plant had considered developing an alternative smelting technology
