Our MIBC is a proven frother widely used  in treating base metals which produces a brittle froth. It is especially suited  for lead and zinc sulphides at very fine particle size and high throughput.

MIBC is also used successfully in coal processing. 

MIBC is an aliphatic neutral frother.

MIBC is used in concentrations as low as 900ppm or less.

 Other uses of MIBC are:

  • Ingredient in lube oil additives for anti-wear and corrosion inhibitions
  • Additive to surface coatings



  1. Composition of MIBC which is synthetic is more stable, giving consistency and predictability in process outcome
  2. Alcohol group provides a selective, often brittle froth, allowing good control and subsequent material transfer through the launders and pumps
  3. Alcohols generally have no collector properties. Presence of collecting and frothing properties in same reagent makes selective flotation difficult. A good frother should have negligible collecting power and also produce a froth which is just stable enough to facilitate transfer of floated mineral from the flotation cell surface to collecting launder.
  4. In processing ore bodies with clays, MIBC can be mixed with pine oil which is less sensitive to presence of clays


MIBC Guiding Rules

Coal, sulphide ores (Au, Ni, Cu, Cu-Mo, Cu-Au)

Froth quality
