我矿的锰粉生产是利用重选的方法。1958年在改进原有设施的基础上,从新设计了一套完整的生产流程,投入了生产。现将投产以来的实践经验简介如下。(一)生产流程利用重选方法处理氧化矿石的生产流程如图1所示。 Mine production of manganese is the use of re-election method. On the basis of improving the original facilities in 1958, we redesigned a complete set of production processes and put them into production. Now put into operation since the practical experience is as follows. (A) the production process using re-election method of processing ore production process shown in Figure 1.
