我车间处理的重选钨精矿,是采取先浮后磁流程。这种粗精矿中含有50％的硫化矿,必须先将它除掉,为以后的烤砂、磁选、电选等工序创造条。在除硫过程中,如何降低台浮和浮选精矿的含砷率,这是精选的重要问题。台浮是粒浮的改进。但粒浮也有一个优点,就是去砷效率高。 The re-election of tungsten concentrates processed by our workshop is based on the first floating magnetic flow. This crude concentrate contains 50% sulphide ore, it must first be removed, for the future roasted sand, magnetic separation, electrowinning and other processes to create a bar. In the sulfur removal process, how to reduce the arsenic rate of flotation and flotation concentrates is an important issue of choice. Float floating is the improvement. But there is also an advantage of particle floats, that is, to arsenic high efficiency.
