我厂自1956年6月份起,在各方面的协助下对全厂原矿、精矿、尾矿、分级、选别、水力旋流器及放槽(固定溜槽的一种型式)等,进行了多次系统的测定。根据测定结果研究分析,针对生产上存在的关键问题,采取措施加以改进,因而一年来使选矿回收率提高了5～6%,主要做法简介于下。磨矿方面矿石的特点是鍚石呈细嵌布,并含有大量氢氧化鈇,锡石嵌布体的大小由0.6～0.008公厘不等,常见者为百分之几公厘到0.1公厘的颗粒。由于鍚石主要是与氢氧化铁紧密结合在一起,因此我们采用了阶段磨矿阶段选别的流程。
I plant from June 1956 onwards, with all aspects of the whole plant ore, concentrate, tailings, grading, sorting, hydrocyclone and put slot (fixed chute type), etc. were carried out Multiple system determination. According to the results of the research and analysis, in view of the production of the key problems, to take measures to be improved, so that the beneficiation recovery rate increased by 5 to 6% a year, the main approach below. Ore grinding ore is characterized by fine stone inlaid cloth, and contains a large number of hydroxide 鈇, cassia cambium body size from 0.6 to 0.008 mm range, common to a few percent of 0.1 to 0.1 mm particle. As the stone is mainly closely integrated with iron hydroxide, so we adopted the stage grinding process of sorting.
