Collectors and Frothers

Flottec has a wide range of collectors and frothers that provide varying levels of power and selectivity for both sulfide and industrial mineral applications.  Each of the following basic product family has a variety of derivatives to accommodate the needs of each particular ore.  In most cases, custom formulations of these basic chemistries are developed to meet the individual needs of the mill.

Xanthates – The M series xanthates, such as M-SIPX, have been the work horse of the sulfide industry. These water soluble salts are strong, non-selective collectors used in a wide variety of applications in alkaline flotation circuits.  They are available in powder, pellet or aqueous forms.

Xanthogen Formates – the Flottec A through G series are water insoluble oily liquids that function at all pH values between 2 and 12 and are selective against pyrite except between pH 6 – 8.  They are stable in both acid and alkaline pH’s and do not age with time.  Compared to xanthates,  these products provide better selectivity at lower dosages and lower pH’s.

Thionocarbamates – The Flottec 1000 series collectors are water insoluble, oily liquids that function well in alkaline flotation circuits (pH 7 – 12)and in particular with porphyritic copper, Cu/Mo, Cu/Au.  They are effective with highly oxidized ores or those containing significant primary slimes.  Thionocarbamates have been found to be extremely efficient as primary zinc collectors on massive sulfide ores where iron sulfides are a problem.

Dithio and Monothiophosphates – the Flottec 2000 series are water soluble salts that exhibit a wide range of properties with respect to selectivity and froth character.  The Dithiophosphates are effective in alkaline flotation circuits and are more selective than xanthates against pyrite.  The Monothiophosphates are effective copper collectors in acid circuits and in LPF circuits.  Monothiophosphates are also effective at all pH ranges for improving gold recovery.  These products are available in the cresyl or alkyl form.  The cresyl products usually display significant frothing properties but depending on the cresylic acid used, these properties can be varied to suite the conditions.

Xanthate Esters – the Flottec 300 series collectors are water insoluble, oily collectors that similar to Xanthogen Formates, functions well in acid and alkaline circuits and are selective against pyrite.  These products are also excellent moly collectors and are often used in conjunction with other collectors in Cu/Mo circuits.  These products are also gaining acceptance in PGM circuits where chrome impurities are a problem.
