 4-Methyl-2-pentanol (IUPAC  name) or methyl isobutyl  carbinol (MIBC) is an organic  chemical  compound  used primarily as a flotation frother for mineral  flotation  in mineral processing industry .

MIBC(Methyl Isobutyl Carbinol) is an  excellent chemical mining reagent used as foaming reagent  both for  non-ferrous metal and non-metallic ores in mineral flotation process.
 Methyl isobutyl carbinol (MIBC) is  mainly used in the flotation plant of non-ferrous oxide ores or fine-grained  sulfide ores containing a large quantity of soil grade
 It is  widely applied in flotation treatment of lead-zinc ore, copper- molybdenum, copper-gold  ore and mineral processing of copper-gold ore . Methyl isobutyl carbinol (MIBC) has particular effect on improving the quality of  concentrate and efficiency of mine recovery.
 Methyl isobutyl carbinol (MIBC), an organic chemical  compound, is a liquid derivative of acetone with a pungent alcohol odor. It has  limited solubility in water, but is miscible with most organic solvents. The  main uses of MIBC are as a frother in mineral flotation and in  the production of lubricant oil additives.
 Frothing, also known as froth flotation, is the process  of selectively separating hydrophobic valuable minerals from hydrophilic waste  gangue. In its simplest form, froth flotation is a method whereby minerals can  be “skimmed” from the surface of “slurry” that is “foamed” with the assistance  of specific chemicals, water and air bubbles.
 MIBC is used as a frother in the flotation process in the  mining of ores, such as copper and molybdenum sulfide, as well as coal.  Compared to other frothers, Florrea’s MIBC product offers fast kinetics and  excellent selectivity, and it forms dry but easy-to-break froths – increasing  both the yield and the efficiency of mineral and metal recovery efforts. This  technique results in an industry-leading way to separate valuable minerals from  extracted ore.
 MIBC can also be used in the production of lube oil  additives (ZDDP) and for anti-wear and corrosion inhibitors – such as in the  manufacture of brake fluid – and as a precursor to some plasticizers.
 Florrea  can provide full range of flotation frothers which is well-suited to enhancing  frother performance. Florrea mining frothers is suitable for Mineral processing  of base metal sulphides, precious metals (gold, silver, PGEs), industrial minerals,  coal and various other non-sulphides.In developing 'frother' products our aim  has been to improve flotation kinetics by influencing the induction time for  solid/bubble contact. More rapid loading of hydrophobic particles into the  froth phase is required in order to reduce gangue entrainment. Through the  development of products that limit water recovery whilst maintaining froth  mobility, we have been able show improvements in grade and/or recovery
 The decision to use a  froth flotation process  creates a range of options for a mine  across collectors, modifier, and frothers. One significant choice for a mine  using the froth flotation process is the selection of an optimal frother to  generate quality froth and to maximize the recovery of minerals and metals from  ore.
 Frothers are neutral molecules that absorb at the  water-air interface, aid in the production of bubbles for flotation, and  stabilize the froth for collection and skimming.
 Some examples of criteria that are used in the evaluation  of frothers include –

  • Molecular  Weight

  • Maximum Foam  Volume – A higher value indicates a stronger foaming  ability of the frother.

  • Foam  Half-life – A longer half-life indicates greater foam  stability.

  • Foam  Comprehensive Index (FCI) – A calculation based on both the foam volume and  the foam half-life measurements; the FCI attempts to create an objective  measure across frothers. 

  • Foam Rise  Velocity – A ratio of foam height to aeration time; a larger  velocity means a lower foam viscosity.

  • Foam  Duration – The length of time that foam persists given a  specific concentration level; the duration of a frother influences both  recovery and the operation of the flotation cell.


Froth Surface Tension – The  ability of a frother to break the surface tension of water.
 Measuring the performance of  frothers is an ongoing research initiative across universities, research  centers, and within the mining industry. In the end, the true measure of a  frother’s performance is in its ability to help a mine recovery a greater  amount of metal or minerals. The importance of choosing the right frother can  have a sizable financial impact, given its ability to affect the resulting  recovery rate of the froth flotation process.
