摘 要:南非多种矿产品产量居世界前列,2010年南非产量排名世界第一的矿产有蓝晶石、铂族金属、钛铁矿、铬铁矿、铬铁和蛭石;金红石、钒和锆石产量居世界第二位;锰矿产量居世界第三位;黄金产量居世界第四位。在世界产量中排名较靠前的重要金属矿产还有锑、锰、铁、铀、锆等金属矿。南非的铬铁、红柱石出口居世界第一位;锰矿出口居第二位;铬矿石出口居第四位。矿业已占南非基础经济中最大部分,介绍了南非各种矿产资源的储量和开发利用现状。Many kinds of mineral products yields in South Africa, which list top position in the world. In 2010, minerals yields of kyanite, platinum group metals, limonite, chromite, ferrochrome, and vermiculite in South Africa ranked first in the world; yields of rutile, vanadium and zircon ranked second in the world; manganese ore yields ranked third in the world; gold yields ranked fourth in the world. At present, there are some important metal minerals yields which rank front line in the world, such as antimony, manganese, iron, uranium, zirconium metal and the concentrate. Export of ferro- chrome and andalusite in South Africa rank first in the world; manganese ore and chromite ore export rank second and fourth in the world separately. Mining industry has occupied the biggest part in founda- tion economics of South Africa, the reserves of each kind of mineral resources and exploration and utiliza- tion situation of South Africa were introduced.
