除银外含有不同矿物型式的金、有色金属(铅和锌)和锰的复合矿是复杂的矿物原料.在没有关于银矿物,特别是淡红银矿、深红银矿和硫锑铜银矿可浮性的充分完整资料时,研究这些矿石的浮选工艺是令人感到困难的.由于矿石中这些矿物含量低,浮选试验将它们选出足够的数量是不可能的.因此,采用了中央地质勘探科学研究所创造的接触仪. In addition to silver containing different mineral types of gold, nonferrous metals (lead and zinc) and manganese complex ore is a complex mineral raw materials in the absence of silver minerals, especially the light red silver, dark red silver and silver sulfur antimony copper It is difficult to study the flotation process of these ores when they are sufficiently complete, and because of the low levels of these minerals in the ores, it is impossible for flotation tests to select enough of them.
