Chemical appearance:
Sodium ethyl xanthate or SEX is typically a yellowish powder or pellet that is soluble in water. It is a xanthate based on the C2 alkyl ethyl alcohol in the sodium salt form.

Chemical application and strengths:

    • Sodium ethyl xanthate or SEX is used in mining as a flotation agent. It is used as a collector and xanthate used especially in copper mines.
    • It can be used for flotation of various minerals that are activated or hydrophobic and float easily such as lead, cobalt, zinc and nickel. It can form insoluble compounds with these metallic ions.
    • Sodium ethyl xanthate is especially important in in froth flotation, where it is used to separate hydrophobic materials from hydrophilic. In mining this is an important operation to recover sulfide ores. For ores such as copper, this process lowers the costs of recovering low grade ores and can save mining companies processing costs.
    • SEX is used a highly selective collector and is the strongest among the xanthates. It is favored for flotation of easily floatable or complex sulfide minerals. It is used in such ores in conjunction with vulcanizing agents.
    • SEX is also used as precipitant in hydrometallurgical processes such as the refining of zinc electrolyte and as sulfidation promoter of rubber.
    • According to a study by Marcel Dekker, SEX works by forming a hydrophobic layer when the polar part of xanthate molecule attaches to the ore particles with the non-polar hydrocarbon part. The particles then rise to the water surface due to air bubbles. Typically on a very small amount of SEX is needed for efficient separation.
  • SEX is part of a family of other Xanthates are used in the mining in the recovery of metal sulphides. The efficiency of xanthates as mineral collectors increases with the length of the carbon chain but this results in a decrease in the selectivity.

Chemical appearance:
Potassium Amyl Xanthate (PAX) is available in the form of yellowish or pale-grey crystals or in the form of free-flowing powder in the purest state. PAX is also available in the form of a solution. PAX is highly water-soluble and emits a slightly unpleasant odor that is similar to that of carbon disulfide or that of decaying cabbage. Another property of PAX is the absorption of moisture from air i.e., hygroscopic nature.

Chemical application and strengths:

    • The properties of PAX as a Xanthate make it the ideal collector for various nonferrous metallic ores. Potassium Amyl Xanthate is the perfect choice for flotation processes of nonferrous metallic ores as a strong yet non-selective collector. PAX works effectively as a flotation reagent in the flotation of oxide minerals such as oxidized sulfide, lead, and copper ores. PAX is also a popular flotation collector for copper-nickel sulfide and auriferous pyrite, thereby indicating its application in the extraction of precious metals. PAX is also implemented in the mining industry as a collector for the ‘scavenger’ flotation operations. Furthermore, PAX also finds notable applications as a rubber chemical.

 

    • The other industrial uses of PAX include its applications as intermediates in various manufacturing processes. PAX is also known for its use as processing aids in rare instances. Furthermore, PAX is also ideal as a surface-active agent.

 

  • The strengths of PAX make its chemical application as a flotation reagent productive. It is easy to manufacture and handle in its solid pellet form. Most important of all, PAX shows effective performance in the recovery of bulk sulfide minerals in a random manner. In addition, it can also be complemented with lime to provide a normal pH operating a range of 9 to 12.

]]> Index Standard Sodium Cyanide ≥ 98% Sodium Hydroxide ≤ 0.5% Sodium Carbonate ≤ 0.5% Moisture ≤ 0.5% Water Insoluble ≤ 0.05%

Chemical appearance:
Sodium cyanide is found either in the white crystalline form or in the form of granular powder. It is also water-soluble and forms a clear and colorless aqueous solution.

Chemical application and strengths:

    • The most important application of sodium cyanide is evident in the extraction of gold. The use of sodium cyanide is still the best method for mining gold.

 

    • Sodium cyanide is a common agent in the leaching process for the majority of gold extraction operations. The primary reason for the use of Sodium cyanide in the extraction of gold is the higher affinity of gold towards cyanide. Sodium cyanide separates gold through oxidizing it and dissolving gold in the presence of oxygen and water. The most important strengths of sodium cyanide in the mining of precious metals are reflected in its cost-effectiveness, higher availability, and better processing.

 

    • The concerns of safety with sodium cyanide could be addressed effectively by referring to the handling process. Sodium cyanide is not self-combustible, and only a tiny amount is required for the extraction of gold. Therefore, properly designed and safeguarded processing facilities could deal out promising benefits of using sodium cyanide.

 

    • Sodium cyanide also finds effective applications in electroplating as well as surface treatment projects. Therefore, it can serve well for metal hardening industries. Furthermore, the toxic properties of sodium cyanide make it an ideal choice as an herbicide.

 

  • It is also known as a cyanide salt and contains an equal number of sodium cations and cyanide anions. The salt is highly poisonous and could be lethal for humans through ingestion. Furthermore, inhalation of dust and exposure to open wounds with Sodium Cyanide is toxic.

Product Overview

Chemical appearance

Dithiophosphate 25s or Hydrogen Phosphorodithioate has an appearance of a deep brown or almost black liquid. Some may classify it as a vandyck brown oily liquid and it has a density of 1.17 – 1.20. It has a PH value of 10 – 13 and a mineral substances percentage of 46 – 49.

Chemical application and strength

Dithiophosphate 25s or Hydrogen Phosphorodithioate is known to be a good flotation collector of copper, silver sulfide, zinc sulfide (activated), and lead ores. It can somewhat be dissolved in water. Also, it can be directly poured into ball mills and surge tanks.

  • Hydrogen Phosphorodithioate is used mainly in the separation flotation process of ores like lead and zinc.
  • Because of its properties it should not be subjected to intense heat like fire or extreme sunlight. Proper packaging must be observed.
  • It is weak in collecting sulfide minerals and pyrite when in alkaline medium. It also is selective in collecting ores.
  • But in contrast, it is very strong collector when in any acidic or neutral medium. It collects sulfide minerals and pyrite without being selective.
  • Different conditions and mediums have different effects on its collecting property when dealing with metal oxidized ores.
  • Dithiophosphates have more difficulty in oxidising which means they are much more stable in different pH values, especially in the pH4 region.
  • Because these don’t produce any froth, pine oil are used or sometimes MIBC as frothing agents.
  • Works great together with xanthates the recovery of concentrates.
  • Dithiophosphates offers stronger collecting power compared to other sub collectors because of its better reaction kinetics.
