本站简介

Mountain Pass supplied most of the world's rare earths in the 1960s-80s, closed under environmental and price pressure, and reopened — the clearest single illustration of how supply chains move and how hard they are to move back.

品位。 High-grade bastnäsite carbonatite, low in thorium relative to monazite ores.

A carbonatite, in cross-section

A rare kind of magma made mostly of carbonate rather than silicate rises as a near-vertical pipe from deep in the mantle. It carries rare earths, niobium and phosphate with it. Where the top of the pipe has been weathered, the ore is already concentrated before anyone touches it. Schematic. Pipes are typically 1–5 km across at surface and continue for kilometres down.

"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。
