阅读说明：本技术 一种重晶石浮选剂及浮选的方法 (Barite flotation agent and flotation method ) 是由 林福平 于 2020-12-31 设计创作，主要内容包括：一种重晶石浮选剂及浮选的方法,重晶石浮选剂包括调整剂、抑制剂、捕收剂；抑制剂为水玻璃,抑制剂至少分三次加入,第一次加入的抑制剂重量为抑制剂总量的65%-75%,第二次加入的抑制剂重量为抑制剂总量的15%-30%,第三次加入抑制剂重量为抑制剂总量的5%-10%,的所述捕收剂重量为所述第一加入的抑制剂重量的60-85%；调整剂调整所述重晶石浮选剂初分选体系的pH值为6.2-6.5;浮选方法包括重晶石浮选剂初分选体系中抑制剂、捕收剂先混合后加入浮选槽,测定浮选槽内pH值、并用调整剂调节浮选槽内混合物pH值至6.2-6.5,重晶石粉也加入浮选槽。本发明的优点是,采用现有浮洗药剂通过三次浮选,就中要实现开路试验条件下重晶石精矿品位95.05%以上、回收率为87.89%以上。(A barite flotation agent and a flotation method thereof, wherein the barite flotation agent comprises a regulator, an inhibitor and a collector; the inhibitor is water glass, the inhibitor is added in at least three times, the weight of the inhibitor added for the first time is 65-75% of the total weight of the inhibitor, the weight of the inhibitor added for the second time is 15-30% of the total weight of the inhibitor, the weight of the inhibitor added for the third time is 5-10% of the total weight of the inhibitor, and the weight of the collecting agent is 60-85% of the weight of the inhibitor added for the first time; the flotation method comprises the steps of firstly mixing an inhibitor and a collecting agent in the primary separation system of the barite flotation agent and then adding the mixture into a flotation tank, measuring the pH value in the flotation tank, regulating the pH value of the mixture in the flotation tank to 6.2-6.5 by using the regulator, and adding barite powder into the flotation tank. The method has the advantages that the existing flotation reagent is adopted to realize the barite concentrate grade of over 95.05% and the recovery rate of over 87.89% under the open circuit test condition through three times of flotation.)
