机柱联合重晶石浮选扩大连续试验研究
|
摘要
对广西盘龙铅锌矿采用浮选机—浮选柱联合浮选系统进行模拟工业生产扩大连续试验研究,其中重晶石粗、扫选作业使用浮选机,精选作业使用浮选柱,在原矿含BaSO_421.54%的条件下,联合系统连续72h运转获得了重晶石精矿含BaSO_496.01%、BaSO_4回收率78.41%的选矿指标,与传统单一浮选机工艺流程相比,机柱联合工艺具有精选次数少、微细粒重晶石回收率高的特点,为重晶石选矿提供了新的技术途径。
The extensive continuous test study was conducted on simulated industrial production of the lead-zinc ore in Panlong,Guangxi by the combined process of flotation column and machine.The barite roughing and scavenging operations were made using flotation machine and its cleaning was conducted by flotation column.With the run-of-mine ore being BaSO_421.54%,the barite concentrate with BaSO_496.89% and the recovery rate of BaSO_4 being 78.41% was obtained by the combined process for continuous 72 hoperation.Compared with the conventional single process of flotation machine,the combined process of flotation column and machine features less cleaning times and high recovery rate of fine grained barite,providing a new technical approach for barite beneficiation.
