Mining solutions
Flotation reagents, flocculants and coagulants, including formulations tailored to your ore.
Flotation reagents, flocculants and coagulants, including formulations tailored to your ore.
Ore beneficiation reagents under our own Inter-Flot® brand: collectors, frothers, process regulators and water treatment chemistry. Formulations are matched to your specific ore and flowsheet.
Inter-Flot® collectors separate valuable minerals and metals from unwanted gangue selectively: recovery goes up, reagent consumption per tonne goes down.
Products for gold-pyrite, copper, zinc, nickel and lead ores, for ores containing platinum group elements and for oxidised sulphide ores.
| Collector chemistry | Inter-Flot | Application and benefits |
|---|---|---|
| Xanthate | PAX, SBX, SIPX, PBX | Standard primary collectors for the flotation of various sulphide ores. |
| Thionocarbamate | 3410, 3411 | High selectivity against pyrite. Suitable for Cu, Mo and PGE; reduces metal losses in the stagewise flotation of lead-zinc ores. |
| Mercaptobenzothiazole | 3415 | Strong sulphide collector — close to xanthates but more selective. Suits gold-pyrite and other sulphide ores. |
| Dithiophosphate blend | 3442 | Higher selectivity with somewhat lower recovery power than xanthate. Suits Cu, Zn, Au, Ag and PGE. |
| Dithiophosphinate | 3442.05 | Strong, selective collector for ores containing Cu, Pb, Au and Pd. |
| Dithiocarbamate | 3440, 3468 | High-performance collectors for pyrite, gold-bearing pyrite and Cu, Zn, Ni and Pb ores. |
| Blend | 3453, 3460 | Special blends for Au-pyrite and Au-arsenopyrite ore flotation. |
| Sodium alkyl hydroxamate | 3446.03, 3446.04 | Selective collectors for oxidised ores, e.g. oxidised copper minerals. |
Anionic collectors work both as a stand-alone reagent and as a secondary collector alongside fatty acids. Non-ionic regulators lift recovery and selectivity; cationic collectors remove silicate gangue from sedimentary phosphates in reverse flotation.
| Collector chemistry | Inter-Flot | Application and benefits |
|---|---|---|
| Alkyl phosphoric esters | A10-P-1, A10-P-3, A-810-P | Selective primary or secondary collectors for direct apatite flotation; also used for carbonate flotation from phosphate rock and for KCl slimes in reverse flotation. |
| Alcohol ethoxylate | N-11, N-12, N-59 | Non-ionic regulators and secondary collectors used with fatty acids to improve recovery and selectivity. |
| Fatty acid amides | M-1, M-2 | Secondary collectors for direct apatite flotation with fatty acids. |
| Blend | A-9-P, M-6 | Collector blends for direct apatite flotation, as the main or as an additional collector with fatty acid. |
| Blend | AN-123 | Improved-selectivity blend for producing several concentrates in stagewise flotation. Suits low-grade apatite ores with 4–5% P₂O₅ or less in the flotation feed. |
| Ether amine | C-6, C-7, C-8 | Selective flotation of silicate gangue from sedimentary phosphate ores (reverse flotation). |
Ether amine and quaternary ammonium collectors give the selectivity needed to cut SiO₂ content in iron ore concentrates.
| Collector chemistry | Inter-Flot | Application and benefits |
|---|---|---|
| Ether amine | C-6, C-7, C-8 | Flotation removal of silicates from iron ores. |
| Quaternary ammonium salt | C-10, C-11 | Highly selective collectors for silicate removal. |
| Collector chemistry | Inter-Flot | Application and benefits |
|---|---|---|
| Fatty amine | C-2 | KCl flotation; works as both a summer and a winter amine. |
| Collector chemistry | Inter-Flot | Application and benefits |
|---|---|---|
| Na hydroxamate | 3446.03, 3446.04 | High performance in rare-earth and pyrochlore flotation. |
| Fatty amine | M-7 | Strong collector for quartz and feldspar flotation, direct kaolinite flotation and reverse silicate flotation from bauxite. |
| Blend | M-6, M-6-2, M-6-3 | Optimised blends for rare-earth, scheelite, barite and fluorite ores. |
| Blend | M-8, M-21 | Secondary collectors for apatite, niobium, scheelite and other ores: better selectivity and lower metal losses in the early stages of stagewise flotation. |
| Blend | MDR-M-10 | Low-selectivity collector for higher recovery, mainly in bulk flotation — for example coal or molybdenum. |
Our frothers build and hold the froth layer at the level the flotation line needs for stable performance.
| Frother chemistry | Inter-Flot | Application and benefits |
|---|---|---|
| Polyglycol | 3404, 3404-M, 250 | For copper, gold and other sulphide ores, and for recovering associated Au and Ag into the concentrate. |
| Alcohol | 3407, MIBC | Moderately strong frother suitable for various ore types. |
| Blend | MDR-K-11 | Strong frother for higher recovery and mass transfer, mainly in bulk flotation. |
| Blend | RM-115 | General-purpose frother matched to your flowsheet. |
