摘　　要：冀南邯-邢地区中小规模铁选厂破碎阶段多采用两段破碎工艺,破碎设备主要为颚式破碎机。最终破碎产品粒度较大,最大粒度不小于50mm。破碎阶段普遍配置磁滑轮干式预选。采用开路磨矿或闭路磨矿,磨矿段数为一段或两段,磨矿设备多采用中小规格湿式球磨机。广泛采用高频细筛进行分级,部分选厂采用螺旋分级机。采用两段或三段磁选,磁选设备为永磁筒式磁选机,型号多样。选别流程有直接磁选和阶段磨矿阶段磁选等方式。精矿脱水采用真空过滤机或沉降池,尾矿处理采用直接排放、水力旋流器浓缩排放或浓缩过筛后固态堆存。该地区铁选厂选矿技术还有有很大的发展空间。Two stage crushing and jaw crusher are used in the technological process in middle and small size concentrators in Handan-Xintai area, south Hebei province. The maximum partical size of crushed product is not less than 50mm. Dry magnetic separation is used in the crushing stage. Open or closed circuit grinding,one-stage or two-stage grinding, as well as middle and small type ball mills are used in grinding stage. High frequency fine screen and mechanical classifier are the most commom used classifier. Two-stage or three-stage magnetic separation with permanent drum magnetic separators is used in the technological process. Separation directly and stage grinding ; separation are the separation process. Vaccum filter or subside pool is widely adopted in concentrate dewatering progress. Tailing dosposal methods are as follows： discharge directly, discharge after concentrate with hydrocyclone and storage after concentrate and screening. There is a broad developing space on mineral processing technology of middle and small size concentrator in Handan-Xintai area,South Hehei province.
