Methyl Isobutyl Carbinol - MIBC

It is a weak foamer (frother) that is most commonly used in mineral flotation, forming brittle foam. Since it is a neutral foamer, it works in both acidic and basic pulp.

It is especially suitable for use in high volume enterprises where fine particle size lead-zinc sulphides are processed. Commercial deliver is made in 175 kg barrels.

It is used as a foamer in the flotation of base metal ores, oxidized minerals, industrial minerals.

Potassium Amyl Xanthate - PAX (KAX)

It is a very strong, non-selective collector from the xanthate group, widely used in the flotation of sulphide ores.

It is generally used as a scraper after more selective collectors.

It can be pale yellow or grayish white; available in powder or pellet form. It has a sharp smell. It is easily soluble in water. It easily decomposes in acid and heat. Commercial deliver is made in 130 kg barrels.

It is used as a collector in the flotation of Cu-Pb-Zn ores, in the flotation of Golden pyrite, in the flotation of Cu-Ni sulphide ores.

Potassium Ethyl Xanthate - PEX (KEX)

It is a collector used in flotation of sulphide ores, low cost from xanthate group, high selectivity, but not strong.

It is used extensively in the flotation of Cu, Ni and Ag ores.

It is especially preferred when maximum selectivity is important. Commercial deliver is made in 130 kg barrels.

It is used in the flotation of sulphide, mineral-containing ores, flotation of Cu-Pb-Zn ores, flotation of Cu-Ni-Ag ores.

Sodium Isopropyl Xanthate - SIPX

Pellet, which is the collecting power of sodium isopropyl xanttate, has a yellowish odor, is slightly stronger than that of ethyl xanthate.

It is mostly used in the flotation of non-ferrous metallic sulfide minerals as a collector. It is also used as a precipitator and a sulfidation enhancer of rubber in hydrometallurgical processes.

Sodium Isobutyl Xanthate - SIBX

Sodium Isobutyl Xanthate Yellow powder or pellet, freely soluble in water, pungent odor.

 It is a stronger collector in the flotation of various non-ferrous metallic sulfide ores. mainly used in flotation processes such as copper, lead, zinc etc.

Copper sulfate

 

Copper sulfate salt is a blue and odorless chemical compound, also known as bluestone. It is completely soluble in water. Commercial deliver is generally made in 25 kg bags and 1 ton big bags.

It is used as a rejuvenating agent (activator) for siphalite, pyrite, pyrothite and other sulfides in the flotation of base metal ores, as a depressant in the re-activation (revitalization) of cyanide suppressed sifalite, pyrite, pyrotite and other sulfides, and in the flotation of some silicate minerals.

Zinc Sulfate

Zinc sulfate is a colorless / transparent crystalline chemical. It dissolves quite well in water. The heptahydrate form is commonly used. It is used in the metal industry, in the flotation of base metal ores. It can be used alone or in combination with cyanide. Commercial deliver is mostly made in 25 kg and 50 kg bags.

It is used as a depressant for the flotation of Pb-Zn, Cu-Zn and Cu-Pb-Zn ores, at alkaline pH, for siphalite.

Sodium Silicate

Sodium silicate, also called ‘’glass water’’, is a chemical in its composition, which contains different amounts of metasilicate, dimetasilicate, orthosilicate and tetracilicate. It is used quite frequently in base metal flotation. It is commercially supplied in colorless, viscous aqueous solutions or in colorless, glassy solid form. Aqueous solutions are offered in 300 kg steel drums.

The mixture prepared with sodium silicate and sodium bichromate is a very good depressant for lead during the flotation of copper from Cu-Pb bulk concentrate containing secondary copper minerals. It is used as dispersant in mineral flotation.

Ethyl Hexanol

It is a colorless, fluid, characteristic odor, high boiling point and low volatility alcohol. It is not a toxic compound. Commercial deliver is made in 170 kg barrels.

It is used as a foamer in the flotation of base metal ores, oxidized minerals, industrial minerals.

Sodium Sulfide

Sodium sulfide is a moisture-retaining yellow chemical that dissolves easily in water. It is a powerful reducer. It is used as a reagent for the flotation of both sulfite minerals and non-metal minerals. Commercial deliver is made in 25 kg bags as straws.

It is used as a dispersing agent for the selective flotation of Cu-Pb-Zn and Cu-Zn ores, as a dispersant in the flotation of very fine minerals (such as <5 µm) in the preparation of metallic copper, oxidized copper, lead and zinc minerals for flotation. It is a good suppressor for quartz.

Sodium Bichromate

Sodium bichromate is an odorless, orange-red colored, crystalline granule. Its solubility in water is quite high. Commercial deliver is generally made in 25 kg bags.

The mixture prepared with sodium bichromate and sodium silicate is a very good depressant for lead during the flotation of copper from Cu-Pb bulk concentrate containing secondary copper minerals.
