一、前言萤石除了用于冶金助熔剂和制铝用作电解质外,亦为氟化学工业中的主要原料。在国外萤石的生产量和消耗量是逐年增长的,见表1。我国随着冶金和化工生产的发展,萤石的产量,必将迅速地增加,对精矿的质量也必将提出更高的要求。 First, Foreword In addition to fluorite for metallurgical flux and aluminum as electrolyte, but also for the fluorine chemical industry’s main raw material. Fluorite production and consumption in foreign countries is increasing year by year, shown in Table 1. With the development of metallurgy and chemical production in our country, the output of fluorite will surely increase rapidly and the quality of the concentrate will surely put forward higher requirements.
