Recovery of feldspar from Ta-Nb tailings in Jiangxi province
摘要
Abstract
Iron element and manganese element are the main impurity elements in the feldspar minerals, causing color stain on feldspar burn products and degradation of the product. In order to solve the problem that iron and manganese melanocratic mineral influence the quality of feldspar product, study on the test of removing iron and impurity of a certain mine is carried out. The results show that coarse grain feldspar products are obtained by adopting the process of “high gradient magnetic separation to purify - hydrocyclone to deslime - spiral chute to recover”. And the fine-grained feldspar products are obtained by adopting the process of “classification then through cyclone to enrich - high gradient strong magnetic separation”. The overall recovery of feldspar is greater than or equal to 93 %, and the total emission volume of the mill tailings is only 8%.Therefore, the comprehensive recovery and utilization of feldspar resources from tantalum-niobium tailings can be realized.关键词
