耐火原料矿物产值仅是工业矿物产值的一小部分,但其作用很重要。耐火原料矿产对钢铁工业的影响很大,钢铁工业使用的耐火原料占耐火原料总产量的65%。世界铬铁矿产量约为1100万吨,大部分用于冶金加工,化学和耐火材料工业的消费用量约占其总产量的12.5%。在远东,最重要的产铬国是菲律宾和新喀尼多利亚。菲律宾提供的高铝铬矿石占世界耐火材料需求的绝大部分。新喀尼多利亚生产的高铬低硅矿石主要用作镍、铜冶炼工业的特殊耐火材料。苏联也是远东主要的耐火原料生产国。
The production value of refractory raw minerals is only a small part of the output value of industrial minerals, but its role is very important. Refractory raw material minerals have a great influence on the iron and steel industry. The refractory raw materials used in the iron and steel industry account for 65% of the total output of refractory raw materials. The world production of chromite is about 11 million tons, most of which is used for metallurgical processing. The consumption of chemical and refractories industry accounts for about 12.5% of its total production. In the Far East, the most important chromium producing countries are the Philippines and New Caledonia. The high-aluminum chrome ore provided by the Philippines accounts for the vast majority of the world’s demand for refractories. The high-chromium low-silica ore produced by New Caledonia is mainly used as a special refractories for nickel and copper smelting industries. The Soviet Union is also a major producer of refractory raw materials in the Far East.
