对于加拿大唯一的一座开采原生钼矿的矿山来说,矿石品位百分之零点零几的微小波动都可能是至关重要的。世界上生产铂的厂家较少,且生产的钥大部分是副产品,开采原生钥矿的矿山就为数更少。原因是这种金属的
For a mine that is the only mine in Canada to produce native molybdenum, tiny fluctuations of about 0.1% of the grade of ore may be of crucial importance. There are fewer producers of platinum in the world and most of the keys produced are by-products, with fewer mines producing primary key mines. The reason is this metal
