Silica Sand Beneficiation Technology Get Breakthrough

First, the resources demand Natural silicon oxide linchpin is formed by the parent rock of granite, quartzite, quartz moxiestone and vein quartz after(prenominal) long-term nature of weathering a quartz sand as the main mineral components like mineral raw materials, and its associated minerals, including feldspar, lithic, mica, stiff minerals and heavy minerals such as zircon, tourmaline, ilmenite, and hornblende. Natural silicon dioxide sand with a cancel rounded grain shape and changeless particle size, are widely used in glass, foundry, petroleum and other industries. Tongliao, Inner Mongolia region (sweet flag card, Yamen yingzi, Iraq Huta), Shuangliao City, Jilin Province, Chengde, Hebei Province, paddock area has a wealth of natural silica sand resources, only the the Tongliao regions of silica sand reserves of more than 600 million tons, due toabove natural silica sand deposit is a typical lacustrine sedimentary sand, mineral composition dominated by quartz, followed by feldspar, a small amount of debris, and heavy minerals, silica sand in the Al2O3 and Fe2O3 content higher using only simplewashing, grading, scrub, magnetised separation or re-election process, can not produce roam glass qualified raw materials and foundry sand.

The other hand, the more the above areas and medium-sized glassworks (Tongliao glassworks such as Fuyao Group Tongliao Co., Ltd., Fuyao shuangliao Limited, Qinhuangdao Yaohua glassworks, Beijing mat Glass Group Company), are not stablesupply of raw materials, overlook of quality raw materials, to some extent, hindered the development of glass manufacturing in unitingern China, over the years, the voice of the construction north of silica sand base has been. Second, the technical advantages At present, the silica sand beneficiation technologies that have been used include: hydrofluoric social disease method, fluorine-free flotation, flotation of alkali. Of hydrofluoric acid flotation environmental pollution, concentrator discharge of yearn water fluoride ion content after treatment a...
