摘要
在物质组成和工艺矿物学研究的基础上,采用预浮选脱炭、脱泥这一关键技术,实现了中低品位钡矿石的浮选富集;浮选精矿用酸洗废液浸出,浸液经除杂后制取沉淀硫酸钡,产品质量符合国家二级标准。此选冶联合工艺能耗少,污染小,所得产品附加值高,为此类矿石的开发利用提供了一种有效新途径。
Based on the study of mineral constitute and technological mineralogy,the enrichment of a mid-low barium ore by flotation was realized by adopting the key technology of pre-flotation to remove carbon and slime.The flotated concentrate was leached by pickling waste liquor and the leaching solution after being removed impurity was used to prepare precipitated barium sulfate,whose quality is up to the second-class national standards.The combined technology of processing and metallurgy with less energy consumption and pollution can bring products with high added value.Meanwhile,it provides a new and effective way for exploitation and utilization of similar ores.
