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.

Ferrous Sulfate Heptahydrate is a hydrate that is a heptahydrate form of iron (2+) sulfate. It is a very useful salt which is made as a result of oxidation of pyrite. Its chemical formula is FeSO4.7H2O. Chemical Appearance Ferrous Sulfate Heptahydrate has the appearance of a blue-green crystalline solid. It is highly soluble in water. Chemical Applications and Strengths Ferrous Sulfate Heptahydrate is an extremely efficient chemical compound and therefore, has many industrial applications. Its main applications and strengths are: Ferrous Sulfate Heptahydrate is most popularly used in mining as a fluid property modulator. It is used for the extraction of oil and gas. It is used in the manufacturing of various medicinal drugs. It is used in general adhesives. In the agricultural industry it is used for lowering the pH of highly alkaline soil. It is used as a soil amendment so that plants have access to the nutrients of the soil.

Ferrous Sulfate Monohydrate is a hydrate that is the monohydrate form of iron (II) sulfate. It is produced from the heptahydrate by heating above 65°C. Chemical Appearance Ferrous Sulfate Monohydrate has the appearance of a white yellow crystalline solid. It is odourless and is soluble in water. Chemical Applications and Strengths Ferrous Sulfate Monohydrate is an extremely efficient chemical compound and therefore, has many industrial applications.

Chemical appearance: Sodium Bisulfite 99% is a chemical compound created by bubbling sulfur dioxide through a solution of sodium carbonate in water. It appears solid white in color with a crystalline or granular texture. Sodium bisulfite also emits a slight sulphurous odor. It is not soluble in water and decomposes at its melting point i.e. 180C. Chemical application and strengths: Sodium bisulfite is a reliable leaching agent for cyanide detoxification in gold mining. Sodium bisulfite is used for detoxification of process leach residues along with air before discharging to the leach residue ponds. Sodium bisulfite serves as the ideal choice for leaching agent in gold mining despite the various doubts and confusion regarding suitable cyanide detoxification agents. Sodium bisulfite also finds applications for clearing oxidative corrosion in large piping systems.

Chemical appearance BLK – 301 has a type of dark brown or amber colour and comes in a liquid form with an oily consistency. It is dissolvable in water and has a density of 1.080 – 1.120 g/m3 and a pH level of 10 – 13. Chemical application and strength BLK – 301 is another great collector in the flotation process of silver, copper, zinc, gold, and molybdenum sulfide. Very soluble in water. It has weak power in the collection of pyrites but is has an excellent selectivity to silver, copper, and gold ores. Only small dosage is used in the flotation process but the BK – 301 still exhibits excellent collection power and great selectivity. It has some frothing characteristics It should be placed in an environment away from exposure to water and extreme heat from fire and sunlight. It should always be placed upright and never upside down

Chemical appearance T – 610 has pinkish orange colour and comes in plaster of powder form. It is chemically stable and has no strong odour. It is sparingly dissolvable in water but very soluble within alkali solutions. Chemical application and strength T – 601 is a great collector which has excellent selectivity characteristics in the right conditions compared to that of SHA or SalicylHydroxamic Acid. It has the ability to form chemically stable chelate with copper, tin, iron, various rare earth minerals, copper, tungsten, and many more. But with alkali and earth metals, the T – 601 forms unstable chelate. Very soluble in water. Exhibits great selectivity characteristics in the flotation of select metal ores, particularly tin. It is always used along with P86 in the flotation process of tin.

Chemical appearance Ethyl Thiocarbamate or Sodium Diethyl Dithiocarbamate has a whitish to pale grey colour and comes in a crystal form. These crystals are easily soluble in water and produce no strong odour. Chemical application and strength Ethyl Thiocarbamate or Sodium Diethyl Dithiocarbamateis another strong type of collector which has characteristics of having strong collection and flotation ability. Compared to other dithiophosphages and xanthates, only a small dosage of it is required to become effective. Soluble not only in water and easily decomposes into carbon disulphide. Has weak collective power with regards to pyrites, but is very selective in the flotation process of various sulfide ores. When compared to dithiophosphates and xanthates, it is found to be more effective in the flotation process of zinc, lead, various polymetallic sulfide, and copper.
