由国家建材局地质研究所承担的“霞石正长岩选矿工艺及其应用研究”项目于1990年5月通过了鉴定。鉴定会是由国家建材局委托中国非金属矿工业总公司组织专家评议。该课题是为积极寻求和开发节能、代碱新原料,推动玻璃、陶瓷工业的发展,同时也为出口创汇增添新产品。通过几年的努力,选矿试验获得成功,为我国霞石选矿填补了空白,在国内该项技术属首创,半工业试验提供的工艺流程及技术指标可作为设计建厂依据。
The project of “Nepheline Sewage Beneficiation and Its Application Research” undertaken by the Institute of Geology of the National Building Material Bureau passed the appraisal in May 1990. The appraisal meeting was commissioned by the National Building Materials Bureau to organize expert appraisals of the China Non-metallic Mineral Industry Corporation. This project is to actively seek and develop energy-saving, new raw materials for alkali, promote the development of the glass and ceramic industry, and also add new products for export earnings. Through years of hard work, the beneficiation test has been successful and has filled the blank for China’s nepheline ore beneficiation. This technology is the first in China, and the process flow and technical indicators provided by the semi-industrial test can be used as the basis for designing and building factories.
