加拿大国际镍公司湯姆森(Thompson)选矿厂,于1960年开始生产,处理的矿石为含铜、镍此例约1∶15的硫化矿。矿石由一台地下颚式破碎机(排矿口为152毫米)破碎后,直接提升至选矿厂的粗矿仓,然后在圆锥破碎机破碎至25毫米及在棒磨机和砾磨机中磨碎至65目,进行泡沫浮选,生产镍精矿、铜精矿和充填砂。镍精矿揚至冶炼厂。铜精矿经脱水和干燥后,运往科珀-克利夫(Copper-Cliff)。从浮选尾矿中回收的尾砂用作地下充填料,细泥揚至尾矿場。
Canadian international nickel company Thompson concentrator, began production in 1960, the processing of ore is copper, nickel, nickel sulfide in this case about 1:15. The ore is crushed by an underground jaw crusher (discharge port of 152 mm) and then directly raised to the coarse ore bin of the concentrator. The ore is then crushed to 25 mm in a cone crusher and ground in a rod mill and a grater mill To 65 mesh, for froth flotation, the production of nickel concentrate, copper concentrate and sand filling. Nickel concentrate Yang to smelter. Copper concentrate is dehydrated and dried before being shipped to Copper-Cliff. Tailings recovered from flotation tailings are used as underground fillings and fine muds reach the tailings yard.
