金堆城钼业公司选矿工艺现状分析

分析了金堆城钼业公司钼浮选工艺现状，提出了优化工艺的对策及措施。指出粗选回收率低的主要原因，一是磨矿粒度较粗，二是分级机效率低，产生过磨；精选回收率低的主要原因是旋流器分级效果差及工艺设备落后。强调铜钼分离作业是精选工艺降铜排泥的关键环节。同时指出加强生产管理，强化分级效果，完善工艺，改造设备是提高选矿技术经济指标的根本途径。

ANALYSIS OF MINERAL PROCESSING TECHNOLOGY STATUS OF JINDUICHENG MOLYBDENUM MINING CORPORATION

The mineral processing technology status of Jinduicheng molybdenum mining corporation was analysed,and the counter measures for improving technology were put forward.The reason why the recovery efficiency of roughing is low is that the grinding size is thicker and the efficiency of classifiers is low;The reason why the recovery efficiency of cleaning is low is that the classification effect of cyclone is not good and the technical equipment is backward.It points out emphatically that the key link of cleaning technology is copper molybdenum separation It also raised that strengthening the administration of production and classification effect,improving technology and renew equipment are basic way to develop technico economical indexes of mineral processing.
