摘要: 针对铅和硫包裹严重,锌在pH=9左右时活性较强,难以抑制的低品位复杂铅锌矿选矿,采用亚硫酸钠和硫酸锌作联合抑制剂,以乙硫氮和丁基黄药作为组合捕收剂,在低pH值条件下,有效地提高了铅、锌的回收率。

关键词: 低品位, 铅锌矿, 组合药剂

Abstract: In view of serious lead and sulfur inclusions, strong activity of zinc at pH=9 and difficult depression in the beneficiation of low-grade complex lead-zinc ore, a combination of sodium sulfite and zinc sulfate was used as depressor and a combination of SN-9# and butyl xanthate as collector, which effectively improved the recovery of both lead and zinc at a low pH value.
