本发明是叙述关于红土矿,特别是关于含镍铁红土矿石的选别方法。红土矿是在热带的气候条件下由碱性岩浆岩风化而形成的伊俄利斯的红土。主要是由铁和铝的氢氧化物组成,并且由于后者的逐渐增加而轉化成为铝土矿。镍铁红土矿中含30—50%铁、0.5—2.0%镍、0.5—3%铬和0.2%以下的钴。这种镍铁红土矿以下简称红土矿。在菲律宾、西里伯岛、新喀里多尼亚和古巴有巨大的红土矿沉积矿床。但是,绝大部分红土矿由于牵联到炼铁的
The invention is described with reference to laterite mines, in particular with respect to nickel-bearing laterite ores. Laterite is the laterite of Ilyesi formed by the weathering of alkaline magmatic rocks in tropical climates. It is mainly composed of iron and aluminum hydroxides, and is converted to bauxite due to the latter’s gradual increase. Nickel-iron laterite ore contains 30-50% iron, 0.5-2.0% nickel, 0.5-3% chromium and 0.2% or less cobalt. This nickel laterite later referred to as laterite. There are huge deposits of lateritic deposits in the Philippines, Celebit Island, New Caledonia and Cuba. However, most of the laterite mines are linked to ironmaking
