就铝硅酸盐工业矿物总产量或销售额而言,在矿物工业所占的比例是微不足道的。就世界范围而言,只有高岭土、长石、硅线石-红柱石被列入五十种最有价值的矿产品的清单上,它们总共才占世界矿物总产量的0.25%左右。如果只考虑非金属的话,它的产量也还不到世界非金属矿物总产量的5%。可以料想,能源矿产品的价值远远超过所有其它矿产品的价值。在南非,金是主要矿产品,占矿产品总价值的60%以上。在南非,建筑用的砂石列于重要矿产品的第八位,而铝硅酸盐矿物汉占矿产品总价值的一个很小的部分。在南非出口的矿 In terms of total industrial output or sales of aluminosilicate minerals, the share of the mineral industry is negligible. Globally, only kaolin, feldspar and sillimanite, andalusite, are included in the list of the 50 most valuable minerals, making up only about 0.25% of the world’s total mineral output. If you consider only non-metallic, it is also less than 5% of the world’s total non-metallic minerals. One can imagine that the value of energy minerals far exceeds the value of all other minerals. In South Africa, gold is a major mineral product, accounting for more than 60% of the total value of mineral products. In South Africa, construction gravel ranks eighth among major minerals, while aluminosilicate minerals account for a tiny fraction of the total value of minerals. Mine exports in South Africa
