起初,研究的马蒂森(Martison)湖矿体是铜矿石,但在30-90米的冰碛物和粘土、污泥的复盖层下面发现了含铌和稀土矿物的高品位磷酸盐。大量粘土与给矿共存使该矿石难于处理,因此脱泥是第一号任务。第一段Cascade磨机排矿的原生矿泥在60目处进行旋流分离,然后泵送至尾矿池。

Initially, the study of the Lake Martison lacustrine ore was copper ore, but high-grade phosphates containing niobium and rare earth minerals were found below the cover of the 30-90 m moraines and clay and sludge . The coexistence of a large amount of clay and ore makes the ore difficult to handle, so slime removal is the number one task. The primary slime from the first Cascade mill is swirled off at 60-mm and then pumped to the tailings pond.
