几年来我矿进行了黑钨和锡石的浮选分离试验和生产。其实质是在草酸介质中添加混合甲苯胂酸浮选锡石。该法在生产中可获得优质锡精矿。但槽内产品(钨精矿)含锡还高,尚需进行磁选或氯化焙烧。考虑到抑钨浮锡方法或磁选法的不足(细粒高锡钨产品的磁选),因此进行了抑锡浮钨的试验工
Over the past few years I carried out the mine tungsten black and cassiterite flotation separation test and production. The essence is to add mixed toluene acid arsenic flotation cassiterite in the oxalic acid medium. The law in the production of high-quality tin concentrate. However, the tank products (tungsten concentrate) containing tin is still high, still need to carry out magnetic separation or chlorination roasting. Taking into account the method of anti-tungsten float tin or lack of magnetic separation method (fine-grained tin-tungsten product of magnetic separation), so tin tin-floating tungsten test workers
