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.

ALC9

A new type of smoothing agent used to reduce nodules during copper cathode production. ALC9 has no effect on the phase disengagement in SX and works effectively at high current densities, producing smooth cathodes compared to Guar and starches.

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.

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.

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.

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.

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.
