| Content | Product Introduction of the Sodium Metabisulfite
Sodium metabisulfite is a white crystalline powder with strong SO2 odor. It is easy to dissolve in water, leaving an unpleasant and familiar smell of sulfur.
Product Feature and Application of the Sodium Metabisulfite
In food, sodium metabisulfite is usually used as food preservative
As a cleaner, the compound is also present in wine and beer because it is used as a bactericide and antioxidant in the brewing or fermentation of beer. If you or someone you know claims to be allergic to red wine, it may be because of the presence of sodium metabisulfite.
As an antibacterial agent, the chemical is also used for water purification, cleaning water pipe and reverse osmosis membrane in desalination equipment.
In addition, its acidity and corrosion resistance make it an effective substitute for sodium bisulfite, which is a chemical used in traditional darkroom photography.
In addition, sodium metabisulfite is also used as a bleaching agent in the manufacture of pulp and textiles, and as a reducing agent in medicine. It is also a preservative in cosmetics.

Sodium borate borax (from persian burah[1][2]), also called sodium borate, or sodium tetraborate, or disodium tetraborate, is an important boron compound, a mineral, and a salt of boric acid. It is usually a white powder consisting of soft colorless crystals that dissolve easily in water.
Borax has a wide variety of uses. It is a component of many detergents, cosmetics, and enamel glazes. It is also used to make buffer solutions in biochemistry, as a fire retardant, as an anti-fungal compound for fiberglass, as an insecticide, as a flux in metallurgy, and as a precursor for other boron compounds.
The term borax is used for a number of closely related minerals or chemical compounds that differ in their crystal water content, but usually refers to the decahydrate. Commercially sold borax is usually partially dehydrated.
| Chemical appearance:
Activated Carbon is the general name assigned for a group of porous carbons. The appearance of activated Carbon depends considerably on the process used for the activation of Carbon. The product is typically charcoal black with varying mesh sizes.
Chemical application and strength:
The primary application of granular activated carbon mesh is evident in the process of cyanidation. Cyanidation is the metallurgical process for mining gold from ore that contains cyanide.
The use of physical activation involves hot gases either through carbonization or oxidation. Granular activated Carbon has an appearance just like the name indicates with the higher surface area for adsorption.
Activated Carbon is produced from sources enriched in Carbon. Therefore, the surface structure of activated Carbon is very porous, and it also has a vast surface area. The large surface area with porous structure and attraction forces help in capturing material components that could be recovered later.
The chemical strength of activated Carbon makes it the ideal choice for extracting gold. Furthermore, activated Carbon also finds reliable applications in the removal of contaminating agents from gases and liquids. Activated Carbon is used for purification of water alongside scrubbing pollutants from gases at different industrial processing facilities.
The applications of activated Carbon in the gold extraction process generally involves its direct introduction in the CIL (Carbon-in-leach) or CIP (Carbon-in-pulp) tanks after leaching. The infected gold comes in contact with activated Carbon, and then the gold is adsorbed on the Carbon.
The coconut shell-based granular activated Carbon also has lower susceptibility to attrition due to hardness. Furthermore, the higher levels of activity help in easier gold adsorption.
