美国公布一项专利NO4606817,提出用泡沫浮选法处理含有黄铁矿、硫化铅、硫化铜、硫化锌、硫化银以及其他金属硫化物的钼矿石。在第1浮选阶段(回收主要部份的)MOS_2精矿,此时不用捕收剂,只加入少量起泡剂;接着使用捕收剂从第1阶段的浮选尾矿中回收混合硫化精矿,并把它分选成硫化精矿和第2阶段的MOS_2精矿。这两个浮选阶段基本工序的产物在精选前,如需要中矿离解可送再磨矿。初始浮选给矿的磨细度为20—30％±0.15毫米;磨矿时的矿浆浓度为30-40％(含固体)。第1阶段起泡剂消耗量,即异丁·甲醇、ODW-250以及其他的松 U.S. Patent No. 4606817 discloses the use of froth flotation to treat molybdenum ore containing pyrite, lead sulfide, copper sulfide, zinc sulfide, silver sulfide and other metal sulfides. In the first flotation stage (recovery of the main part of the MOS_2 concentrate, this time without collector, adding only a small amount of foaming agent; followed by the collector from the first stage flotation tailings recovered mixed sulfide Mine, and classify it into sulfide concentrate and Stage 2 MOS 2 concentrate. The two flotation stages of the basic processes of the product prior to selection, such as the need for dissociation of ore can be sent to grinding again. The initial flotation gives 20-30% ± 0.15 mm fineness to the ore and 30-40% (solids content) at the time of grinding. Phase 1 foamer consumption, isobutyl methanol, ODW-250, and other pine
