前言 我国钨矿资源丰富,分布辽阔,生产单位众多,产量长期居世界首位;同时,钨精矿是重要的出口商品,在国际市场有举足轻重的地位。钨是现代工业的重要原料,在钢铁、石油、机械、电器以及尖端工业都有重要用途。因此,迅速提高钨矿生产技术水平、充分发挥钨矿资源的优势,对加快“四化”建设具有重大现实意义。 Preface China’s tungsten ore is rich in resources, vast in distribution and has many production units, ranking first in the world in output for a long time. Meanwhile, tungsten concentrates are important export commodities and have a pivotal position in the international market. Tungsten is an important raw material for modern industry and has important uses in steel, petroleum, machinery, electrical appliances and cutting-edge industries. Therefore, the rapid improvement of tungsten production technology, give full play to the advantages of tungsten resources, to speed up the “four modernizations” of great practical significance.
