摘　　要：这是一篇矿物加工工程领域的文章。重晶石是一种重要的非金属矿物,具有比重大、无毒、无磁性、易吸收射线等特点,主要用于石油天然气钻井泥浆加重剂、制备含钡化工产品和钡合金,我国是重晶石的主要出口国。本文对贵州某地低品位重晶石进行选矿实验研究,用碳酸钠作调整剂、水玻璃作抑制剂、十二烷基硫酸钠作捕收剂,经过“一粗一扫二精”的闭路流程实验,取得了BaSO_(4)品位90.38%、回收率91.78%的重晶石精矿,实验技术指标良好,精矿达到化工用重晶石一等品要求。本研究成果可为重晶石资源的开发利用提供重要的技术支撑和参考。This is an essay in the field of mineral processing engineering.Barite is an important non-metallic mineral with the characteristics of large proportion,non-toxic,non-magnetic,easy to absorb rays,etc.It is mainly used for oil and gas drilling mud weighting agent,preparation of barium-containing chemical products and barium alloys.China is a major exporter of barite.This paper conducts beneficiation test research on low-grade barite ore from Guizhou,China.After the closed-circuit test of “one roughing,one scavenging and two cleaning”,sodium carbonate as regulator,water glass as inhibitor and sodium dodecyl sulfate as collector,a barite concentrate with a BaSO_(4) grade of 90.38% and a recovery of 91.78% has been obtained.The test technical indicators are good,and the concentrate meets the requirements of the first grade chemical barite.The research results can provide important technical support and reference for the development and utilization of barite resources.
