The Materials Atlas

本站简介

The Pilbara moves more tonnage than any other mining district on the planet, on private heavy-haul railways running to purpose-built ports. It is the physical backbone of Asian steelmaking.

品位。 Direct-shipping hematite that needs crushing and screening but no concentration.

A banded iron formation

Over two billion years ago, oxygen produced by early life met iron dissolved in the oceans and precipitated it. The result is millimetre-scale bands of iron oxide and chert laid down over hundreds of millions of years. Later weathering leached the silica out of parts of it, leaving almost pure iron ore. Schematic. Enriched zones can be tens of metres thick and hundreds of metres long. Original diagram, The Materials Atlas.

"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。

Iron Ore

Rust-coloured rock that is roughly one-third to two-thirds iron, and the single largest tonnage the mining industry…

PrimaryFe

"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。
