柴河铅锌矿的锌精矿,因氧化矿多,粒度较细,浮选剂加入量大,矿浆粘度大,含水率高达14～17%,呈糊状。这种精矿在运输过程中,从车厢缝隙的流失量很大;汽车上下坡时,由于精矿在车内流动,重心偏移,汽车零件损坏重严。同时,装卸也很困难,冬季严寒,精矿冻结,不但损坏、积压车辆,而且浪费大量劳动力,给冶炼厂带来很大困难。过去虽千方百计设法降低精矿含水率,但收效甚微。为了解决上述问题,去年在东北有色金
Zinc concentrate of Chaihe lead-zinc mine is more moxibustion due to more oxide ore and smaller particle size. Large amount of flotation agent is added, the viscosity of slurry is high, and the water content is as high as 14-17%. This concentrate in the transport process, the loss of a large gap from the carriage; car downhill, due to concentrate in the car flow, center of gravity shift, serious damage to automotive parts. At the same time, loading and unloading is also very difficult. The cold winter and the frozen ore concentrate not only damage and backlog the vehicles, but also waste a lot of labor and bring great difficulties to the smelter. Although in the past tried every means to reduce the moisture content of concentrate, but with little success. In order to solve the above problems, there was a gold color in the northeast last year
