Our Products.

Copper:

  • Frothers
    HydrofrothTM Range

    Optimal froth conditions are created by effectively controlling the laminar layer development and allowing for proper gangue drainage. Combined with improved water rejection ability that promotes final concentrate grade improvements, the HydrofrothTM range also speeds up kinetics whilst maintaining froth mobility.

  • Flocculants
    Brontë Range

    Polyacrylamides with a range of different charge strengths and molecular weight, improve the settling rate at various solid and liquid separation stages in mineral processing – such as thickening of flotation concentrates, recovery of pregnant leach liquors and dewatering of tailings.

  • Smoothing Agent
    ALC7G

    ALC7G Smoothing Agent is a mixture of modified polymers. It’s use in SX/EW results in quality improvements in ordered structure and smoothness of the cathodes when compared to other products. It is water soluble at room temperature which results in less fish-eyes and no loss of reagent. Due to high solubility the prepared solutions are less viscous with better dispersion in the electrolyte. The high solubility also reduce line blockage and pump maintenance.

  • Collectors
    TLQ2

    A specialised oil-based liquid collector which offers improved selectivity of valuable sulphide minerals over xanthates. Effective in increasing the flotation kinetics and grade of chalcopyrite/chalcocite compared to xanthates. Low dosage required and does not break down under low alkaline conditions.


    TLQ2-DX

    A formulated liquid sulphide collector targeting chalcopyrite in ores that contain high levels of pyrite as a contaminant. Based on the selective nature of TLQ2 towards copper, the TLQ2-DX further enhances the selectivity. Through rejection of pyrite in the roughing stage, build up is not experienced in the cleaner circuit. Typically works at very low doses while improving flotation kinetics as well as concentrate grade.


    DLQ2

    A liquid sulphide collector that can be used as a complete replacement or as a secondary collector with xanthates. Selective towards base metal sulphides, as well as sulphides containing gold. Lower dosage required compared to xanthates.


    DLQ5

    A liquid collector designed for the differential flotation of Cu/Pb/Zn circuits. DLQ5 collects copper and lead whilst allowing for effective rejection of zinc. The rejection can be further enhanced with the use of a depressant.


    MLQ1

    A water-soluble collector used for copper ores containing sulphide and oxide minerals. Collecting power compares to PAX, however more selective. Also effective in collecting gold sulphides.


    AM810

    A liquid C8/C10 hydroxamate designed for the flotation of oxidized base metals. Forms a complex through chelation therefore a wider range of oxide minerals can be floated. Works best as a secondary collector after sulphidising with NaHS/Na2S.

  • Depressants
    Revadep CM3

    A metallurgical grade CMC used to depress Talc by rendering the surface of the gangue hydrophilic.


    Revadep 5050

    Disperses fine material and depresses siliceous gangue such as quartz, mica, calcite and alumina-silicate.


    Revadep Cu++

    A strong dispersant which alters the charge of fine gangue material, thereby repelling each other. This reduces pulp viscosity which allows for better froth drainage, resulting in an increase in the concentrate grade. Effective in the rejection of carbon.


    Revadep RB

    A natural polyphenol designed to disperse and depress clay gangue found in sulphide-bearing base metal ores. Very effective in improving concentrate grade. Dissolves easily in water.

Combined with improved water rejection ability that promotes final concentrate grade improvements, the HydrofrothTM range also speeds up kinetics whilst maintaining froth mobility.

  • Flocculants
    Brontë Range

    Polyacrylamides with a range of different charge strengths and molecular weight, improve the settling rate at various solid and liquid separation stages in mineral processing – such as thickening of flotation concentrates, recovery of pregnant leach liquors and dewatering of tailings.


  • Collectors
    DGQ4

    This has shown an increase in recovery of fine particles (< 25μm) and this is attributed to its effect on the behaviour of the froth phase. When used in dual-collector reagent suites with xanthates, the recovery of free gold and gold-bearing sulphides is markedly improved. As the silver content of the gold surface increases, DGQ4 adsorption increases dramatically. Research has concluded that the addition of DGQ4 results in a more stable froth phase in addition to the synergistic interactions between the reagent and primary xanthate collector - hence the improved floatation performance.


    MGQ2

    MGQ2 adsorption occurs on pure gold surfaces as both monomeric and dimeric species. MGQ2 has a higher affinity for gold particles with low silver content, thus using the collector in low silver grade ore results in improved recoveries. It is an alternative to the conventional xanthate collectors and requires lower dosages to obtain high recoveries in sulphide-mineral flotation.


    TGQ4

    The collector by having both a short chained and a branched alkyl group renders the minerals’ surfaces hydrophobic at a faster rate than most collectors resulting in improvrd flotation performance when blended with other collectors. The liquid nature of the oily product improves the shelf life significantly, as well as adding to the ease of dosing, as no additional make-up is required.


  • Depressants
    Revadep CLA-D

    Ore constituents such as clay-forming minerals and hydrated iron oxides can hinder the attachment of free gold onto the bubble surface. The hindrance of the free gold attachment to the bubble is more pronounced in the fine size classes with the slimes coating, otherwise floatable minerals. Revadep CLA-D in small amounts can act as a dispersant having a positive impact on both the flotation rate and overall gold recovery.

    Polyacrylamides with a range of different charge strengths and molecular weight, improve the settling rate at various solid and liquid separation stages in mineral processing – such as thickening of flotation concentrates, recovery of pregnant leach liquors and dewatering of tailings.


  • Collectors
    TPG4

    A neutral oily specialised liquid sulphide collector that can be used as a complete replacement for xanthate collectors. The collector is both a short chained and a branched alkyl group, rendering the minerals’ surfaces hydrophobic at a faster rate than the xanthate collectors. This is very beneficial when dealing with non-sulphide PGMs, such as tellurides and arsenides that have slow flotation kinetics. Benefits are: improved grades, rejection of iron-impurities and very low doses.


    DPG4

    A liquid sulphide collector that can be used as a complete replacement or as a secondary collector with xanthates. The minimum interaction between the DPG4 collector and mineral surface is sufficient to impart hydrophobicity to the mineral surface. The residual DPG4 collector molecules aggregates onto the bubble-particle interphase. This process stabilises the agglomerate, resulting in higher concentrate grades. When DPG4 is used as a secondary collector, the collector adsorbs on strong sites and the xanthate adsorbs on the remaining weaker sites on the sulphide mineral surface. This results in a greater surface coverage, thereby enhancing the adsorption of xanthate onto sulphide minerals and improving the PGM recovery.


    DPG6

    In an alkaline circuit, flotation reagent is more selective against iron sulphides and displays weak collective power towards pyrite. In relation to the PGM industry, a key characteristic of the collectors is its fast kinetics contribution which is key when dealing with the slow floating minerals. The liquid nature of the product significantly improves the shelf life and adds to the ease of dosing as no additional make-up is required.

  • Depressants
    Revadep Tal-D

    Talc is a naturally floating gangue mineral found in PGM ores and has a hydrophobic nature that increases with milling intensity. As a result, talc is a major concern for PGM producers who are mandated with fine grind milling. Revadep Tal-D adsorbs onto the talc surface, making the surface hydrophilic, thus reporting to the tailings and improving the grade of the concentrate.


    Revadep Sil-D

    Fine grinding associated with PGM beneficiation often results in formation of slimes that coat the mineral particles, retarding collector adsorption. Silicates are a common contaminant of PGM concentrate. Silicates are efficiently depressed using Revadep Sil-D. The product utilises the ability to completely bond with activating cations in a chelating fashion, thus depressing the targeted gangue minerals, while also dispersing fine clay-like particles. This allows the clean mineral surface to interact with the collector.


    Revadep Pt+

    Fine grinding associated with PGM beneficiation often results in formation of slimes that coat the mineral particles, retarding collector adsorption. Silicates are a common contaminant of PGM concentrate. Silicates are efficiently depressed using Revadep Sil-D. The product utilises the ability to completely bond with activating cations in a chelating fashion, thus depressing the targeted gangue minerals, while also dispersing fine clay-like particles. This allows the clean mineral surface to interact with the collector.

The Poly range of collectors are specifically formulated for the differential flotation of polymetallic minerals in Copper-Lead- Zinc ores. The collectors are selective towards minerals like Chalcopyrite (CuFeS Galena (PbS) and Sphalerite (Zn,Fe)S in the respective circuits during differential flotation. Although xanthates with various chain lengths are commonly used for the selective flotation of Chalcopyrite, Galena and Sphalerite, specialised collectors can enhance the selective recovery of the minerals. Conventional polymetallic flotation involves the flotation of Cu at pH 6-7, Pb at pH 8-9 and Zn at alkaline pH 10-11 and the PolyQ range are applicable to these flotation conditions. During the selection process of an applicable collector, the ore mineralogy, circuit conditions and total reagent suite (depressants, activators and frothers) play an important role in selecting the most efficient collector. Collector type and dosage can be selected through laboratory batch flotation tests and Axis House technical representatives are able to advise on the application and selection of the appropriate collector.




  • PolyQ Cu Collectors

      The selective Cu collectors can be applied as alternatives to xanthates and are effective at significantly lower dosage (30% of xanthate dosage). These collectors perform over a wide pH range and can be applied in conjunction with sulphide/non-sulphide gangue depressants that are dosed in the Cu circuit.


      PolyQ-472
      PolyQ -402
      PolyQ -305
      PolyQ -DX

  • PolyQ Pb Collectors

      The Pb collectors are applied in Pb-Zn circuits or Cu-Pb-Zn circuits after the Cu flotation stage. Compared to low to medium chain length xanthates, it is very selective over Zn minerals and targets Pb sulphide minerals in the presence of typical sulphide depressants like ZnSO4 and Cyanide. PolyQ Pb collectors are effective over a pH range and can be applied to most Pb-Zn flotation circuits. The Pb collectors are also effective in recovering any associated silver minerals that are common in some galena ores.

      PolyQ -2
      PolyQ -5


  • PolyQ Zn Collectors

      The Zn sulphide collector range is aimed at maximising the Zn recovery while maintaining selectivity against sulphide gangue like pyrite. The collectors are typically applied after the reactivation of Sphalerite with CuSO4 and at elevated pH levels. Compared to medium to high chain length xanthates, these collectors are dosed at 30% to 50% of the xanthate dosage.
