1. Application
Regulator BK511 is mainly used as copper and pyrite inhibitor during copper molybdenum separation flotation, which has high selectivity and strong restraint force. Compared with conventional inhibitor sodium sulfide and cyanide, BK511 has not only good using effect, but has low toxicity and is easily for biological degradation.BK511 is firstly developed by Beijing mining and metallurgy research institute in China, and is first used in copper and molybdenum separation process, of which intellectual property rights is owned exclusively by BGRIMM.
2. Chemical property
Regulator BK511 is a kind of lemon yellow transparent oily liquid, which has sulfide smell without impurities, and is soluble in water, of which quality is table, nonflammable. It is a composite safe and high effective copper andpyrite inhibitor.
