such as hand sorting, gravity separation, magnetic separation and flotation. And the suitable method is adopted based on the mineral properties. For andalusite ore containing larger single crystals, process of gravity separation-magnetic separation can be used to obtain coarse concentrate. Flotation is the most common and effective method for fine andalusite flotation. Prior to andalusite flotation, adequate......
. And pH value and conductivity increase. The flotation tests show that magnetized water have greatly influence on flotation process with chalcopyrite. When the magnetic field intensity increases from...; Effect of magnetic induction with water and reagents on flotation process 由图10可见,用不同磁场强度处理的水和丁基黄药溶液对黄铜矿的影响不一样,且随着磁场强度的增加,在其余条件相同的情况下,磁化水时黄铜矿的回收率从未磁化时的86.74%提升到90.19%,而磁化丁基黄药时黄铜矿的回收率从未磁化的86.90%提升到90.44......
