In sulfide copper flotation, the collector you choose decides everything—grade, recovery, reagent cost, and how smoothly your circuit runs. Traditional xanthates and dithiophosphates ("black agents") get the job done, but they come with trade-offs: strong odor, harsh handling, and limited adaptability to low-grade ores. Thionocarbamates, while selective, often underperform on lower-grade feeds. BK916 changes that equation.

Engineered for Sulfide Copper Ores and developed by BGRIMM, BK916 is a green, high-efficiency collector purpose-built for sulfide copper ore flotation. It overcomes the pungent odor issues of conventional xanthates and dithiophosphates, and eliminates the poor adaptability of thionocarbamates to low-grade ores.

Why BK916 Stands Out:

l Safe & Stable – Low odor, easier handling, better for your operators and site environment

l Strong Collecting Power – Higher copper grade and recovery

l Excellent Selectivity – Cleaner concentrates, less gangue carry-over

l Green & Eco-Friendly – Aligned with modern sustainable mining goals

l Superior Au & Ag Recovery – Captures more value from associated precious metals

l Proven Metallurgical Performance:

Copper recovery: +1 to +2 percentage points

Associated gold & silver recovery: +3 to +5 percentage points
