AERODRI

AERODRI dewatering aids are used to reduce cake moisture in the filtration of mineral slurries, such as sulfide flotation concentrates, iron ore concentrates and coal concentrates and tailings and alumina trihydrate in the Bayer process. The dewatering aids increase filteration throughput in mineral processing by reducing moisture content and improving release of the filter cake. The dewatering aids offer unique chemistry that can significantly increase production rates and lower energy and transportation costs.

Bauxite

Bauxite, an aluminium ore, is the world's main source of aluminium. It consists mostly of the minerals gibbsite (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite and haematite, the clay mineral kaolinite and small amounts of anatase (TiO2) and ilmenite (FeTiO3 or FeO.TiO2).Bauxite is usually strip mined because it is almost always found near the surface of the terrain, with little or no overburden.Usually, bauxite ore is heated in a pressure vessel along with a sodium hydroxide solution at a temperature of 150 to 200 °C. At these temperatures, the aluminium is dissolved as sodium aluminate (the Bayer process). The aluminium compounds in the bauxite may be present as gibbsite(Al(OH)3), boehmite(AlOOH) or diaspore(AlOOH); the different forms of the aluminium component will dictate the extraction conditions. The undissolved waste, bauxite tailings, after the aluminium compounds are extracted contains iron oxides, silica, calcia, titania and some un-reacted alumina. After separation of the residue by filtering, pure gibbsite is precipitated when the liquid is cooled, and then seeded with fine-grained aluminium hydroxide. The gibbsite is usually converted into aluminium oxide, Al2O3, by heating in rotary kilns or fluid flash calciners to a temperature in excess of 1000oC. This aluminium oxide is dissolved at a temperature of about 960 °C (1,760 °F) in molten cryolite. Next, this molten substance can yield metallic aluminium by passing an electric current through it in the process of electrolysis, which is called the Hall–Héroult process, named after its American and French discoverers.Bauxite is the main source of the rare metal gallium.

Brucite

Brucite is the mineral form of magnesium hydroxide, with the chemical formula Mg(OH)2. It is a common alteration product of periclase in marble; a low-temperature hydrothermal vein mineral in metamorphosed limestones and chlorite schists.Brucite is often found in association with serpentine, calcite, aragonite, dolomite, magnesite, hydromagnesite, artinite, talc and chrysotile.Brucite is used as a flame retardant because it thermally decomposes to release water in a similar way to aluminium hydroxide and mixtures of huntite and hydromagnesite.It also constitutes a significant source of magnesium for industry. Brucite can easily be milled down to a sub-10 micron particle size giving it reaction and neutralization times equal to the Magnesite and Magnesium Chloride sources of Mg(OH)2. Brucite is becoming more popular as a component in flame retardant products. Alumina Trihydroxide (ATH) is currently the largest mineral filler component in such products but brucite has been gaining more and more attention because of its superior properties. It has a lower smoke generation and a higher stability field than ATH. Brucite is often used as a flame retardant filler in the plastic and paper industries and in the field of environmental protection. It is also used as an additive in the fertilizer. Brucite is used as an additive in steel.

Calcium

Calcium is a alkaline earth metal, and is the fifth most abundant element by mass in the Earth's crust. It is essential for living organisms, particularly in cell physiology, where movement of the calcium ion Ca2+ into and out of the cytoplasm functions as a signal for many cellular processes. As a major material used in mineralization of bones and shells, calcium is the most abundant metal by mass in many animals. It is uesd as a reducing agent in the extraction of other metals, such as uranium, zirconium, and thorium, as a deoxidizer, desulfurizer, or decarbonizer for various ferrous and nonferrous alloys, and as an alloying agent used in the production of aluminium, beryllium, copper, lead, and magnesium alloys. It is also used in the making of cements and mortars to be used in construction and in the making of cheese, where calcium ions influence the activity of rennin in bringing about the coagulation of milk.

MOLYFLO

MOLYFLO is a Amber brown liquid with mild odor.It shows superior recovery and selectivity over kerosene and diesel, which results in more consistent operations over extended time periods. It can be used with all conventional reagents, and is stable over wide pH ranges. It can also be used as a primary or scavenger collector for molybdenite in primary molybdenite ores and in copper-molybdenum bulk flotation processes.

Mercury

Mercury is the only metal that is liquid at standard conditions for temperature and pressure. It is used primarily for the manufacture of industrial chemicals or for electrical and electronic applications. It is used in some thermometers, especially ones which are used to measure high temperatures. A still increasing amount is used as gaseous mercury in fluorescent lamps, while most of the other applications are slowly phased out due to health and safety regulations and is in some applications replaced with less toxic but considerably more expensive Galinstan alloy. Mercury and its compounds have been used in medicine, although they are much less common today than they once were, now that the toxic effects of mercury and its compounds are more widely understood. The element mercury is an ingredient in dental amalgams. Mercury, as thiomersal, is widely used in the manufacture of mascara. The largest use of mercury in the late 20th century was in the mercury cell process where metallic sodium is formed as an amalgam at a cathode made from mercury; this sodium is then reacted with water to produce sodium hydroxide. Historically, mercury was used extensively in hydraulic gold mining in order to help the gold to sink through the flowing water-gravel mixture. RoHS bans mercury from certain electrical and electronic products, and limits the amount of mercury in other products to less than 1000 ppm.

GEMPOLYM

GEMPOLYM is widely used as a flocculant to produce liquid solid separation. It is also used in flotation. It acts as a depressant for talc or insoluble gangue mined along with the valuable minerals. It increases the permeability of the filter cake, resulting in an increased filtration rate. It flocculates in an acid environment.
