이 사이트에 대하여

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.

품위. 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.

'품위'란 암석 중 유용 성분의 비율입니다. 품위 0.5%의 구리 광산은 구리 1톤을 출하하기 위해 암석 199톤을 버립니다. 이 단 하나의 수치가 어떤 광체가 실제 광산이 될지, 아니면 단순히 흥미로운 지질 표본에 그칠지를 결정합니다.

"부산물"이란 누군가 의도적으로 찾아서가 아니라, 같은 암석에 우연히 존재하기 때문에 회수되는 금속이다. 따라서 그 공급은 자체 경제성이 아닌 주산물의 경제성을 따른다.
