加拿大国际镍公司的 SO_2空气脱氰新工艺已在不列颠哥伦比亚省 Stewart 附近的金选厂工业应用。Scottie 金矿有限公司得到国际镍公司的许可,最先采用此新工艺。在国际镍公司的帮助下,Scottie 公司于1982年7月安装了废液处理系统。试验后,于9月对排出废液和尾矿浆的混合物处理达到了稳定作业。该系统使流出的矿浆从平均百万分之200的氰化物总量减至百万分之3以下。新工艺还能脱除铁、铜、镍和锌等贱
Canadian International Nickel’s SO_2 air decyanation process has been applied at a gold concentrator plant near Stewart, British Columbia. Scottie Gold Mines Ltd. is licensed by Nickel International to adopt this new process first. With the help of Nickel International, Scottie installed a waste disposal system in July 1982. After the test, the mixture discharged from the waste liquid and the tailings slurry was stabilized in September. The system reduces outflow of pulp from an average of 200 parts per million cyanide to less than 3 parts per million. The new process also removes iron, copper, nickel and zinc and other cheap
