一、前言石英又称硅石,是一种常见的非金属矿物原料,其应用领域十分广泛。我国的石英选矿提纯及深加工开发利用的比较晚,并且主要用于建筑工业,玻璃制造,陶瓷工业和铸造工业,这些领域的一个共同点就是石英的需求量大,原料质量要求低。目前,国外以美国的石英砂选矿提纯技术最为先进,特点是工业化产量大、装备专业化和生产自动化
First, the foreword Quartz, also known as silica, is a common non-metallic mineral raw materials, its application is very broad. China’s quartz mineral processing and purification of deep processing of development and utilization of the late, and is mainly used in the construction industry, glass manufacturing, ceramic industry and foundry industry, one of the common in these areas is the large demand for quartz, raw materials, low quality requirements. At present, foreign countries to the United States quartz sand dressing and purification technology is the most advanced, characterized by large industrial output, equipment, specialization and production automation
