本站简介
Brine is pumped from beneath the salt crust into ponds and left to the sun for a year or more. The desert does most of the processing for free — but the water accounting is contested.
品位。 Unusually high lithium concentration and a very favourable magnesium-to-lithium ratio.
"品位"是指有用成分在矿石中所占的百分比。一座品位为0.5%的铜矿，每产出一吨铜就需丢弃199吨废石。这一个数字，决定了一个矿体究竟是可开采的矿山，还是仅具地质意义的有趣岩石。

"副产品"是指因与主矿种赋存于同一岩体而被回收的金属，并非专门勘探的目标。因此，其供应量受主矿种经济性驱动，而非自身供需关系。
