加拿大国际镍公司的克拉雷倍尔选矿厂位于铜崖选矿厂以北约1英里。该厂包括接受粗矿石(-8英寸)和储存设备、湿筛和破碎到-3╱4英寸。粉矿磨到15％+65目,其后有磁选和浮选。该厂的任务是采用磁选和浮选生产一种磁黄铁矿精矿,一种铜镍混合精矿和尾矿。这些精矿用泵送到一英里多远的铜崖选矿厂去分离铜镍和硫化铁精矿。尾矿用泵送到萨德伯里地 Canadian International Nickel’s Clarebel Concentrator is about 1 mile north of the Copper Cliff beneficiation plant. The plant consists of accepting coarse ore (-8 inches) and storage equipment, wet screened and crushed to -3 ╱ 4 inches. Powder mill to 15% + 65 mesh, followed by magnetic separation and flotation. The plant’s mission is to produce a pyrrhotite concentrate, a copper-nickel mixed concentrate and tailings using magnetic separation and flotation. The concentrates are pumped to a mile and a mile away from the copper-copper concentrator to separate copper-nickel and iron sulphide concentrates. Tailings pumped to Sudbury
