Potassium Amyl Xanthate (PAX) 90%min

Potassium Amyl Xanthate (PAX) 90%min

Potassium amyl xanthate is one of the most powerful flotation collector widely used in mineral processing. It is relatively unselective and has a strong tendency to float iron sulfides unless depressants are used. It is used as a good mining reagent for the flotation treatment of all sulfide minerals, Cu/Ni sulfide ore, zinc ores, as well as gold associated with pyrite( gold containing iron sulfides). This mining chemical tends to recover all sulfides if circuit pH is maintained between pH 7 and pH 9.

SYNONYMS

Potassium Amyl Xanthate (PAX) / Flottec PAX / XANTATO AMILICO DE POTASIO/ Flomin C3505 / AERO 350

CAS Number: 2720-73-2

Molecular Formula: C₆H₁₁KOS₂

PRODUCTION OF XANTHATES:

RAW MATERIALS: are Carbon Disulfide, Caustic Soda (Sodium Hydroxide), or Potash (Potassium Hydroxide) and determined alcohol, which provides it with collecting properties in flotation processes of metallic and polymetallic minerals.

WHAT IS THE QUALITY OF YOUR XANTHATE?

The production of pure xanthates requires pure raw materials and then the reaction must also be driven to completion. This requires sophisticated process design and control of the manufacturing process which, in turn, influences the price and metallurgical efficiency of the product.

XANTHATE APPLICATION:

Potassium Amyl Xanthate, strong, unselective collector
, with 5 carbon molecules in its chain, is strong, unselective, and is ideal for sulfide gold operations where all sulfide minerals need to be recovered.

It can be applied for the flotation of all types of sulfide minerals in combination with weaker xanthates.

Xanthates in mining

Xanthates have been the workhorse of sulfide mineral flotation since the 1920s (Harris 1989), and they represent the largest volume of any sulfide mineral collector. Xanthate collectors are salts consisting of a non-polar hydrocarbon group, which provides the hydrophobicity to a sulfide mineral, pointing outward from the mineral to the solution, and a polar group that adsorbs onto the sulfide mineral surface.

All Xanthates are water-soluble and are usually fed in as aqueous solutions in a 5 to 20% strength.

These reagents are widely used for all sulfide minerals, with a high tendency to float iron sulfide, except when using depressors. They cannot be used in highly acidic circuits, as they tend to decompose.

Advantages of Xanthate.

1. The least expensive sulfide mineral collector-Inexpensive compared to Specialty Collectors
2. Easy to manufacture and available in solid pellet form for easy handling
3. Dosage: in-plant environment, they’re fed at active concentrations of 5% or less in water.
4. Very good at recovering in an unselective manner bulk sulfide minerals, including sulfides.
5. Can be used with lime to give a pH operating range of 9-12.
6. Can be used as a sole collector in a sulfide mineral plant.

Plant Operation Tips:

- The sequence of addition of modifiers, collectors, and frothers is of great importance, especially when sulphidising agents and other activators and depressants are involved. 


- Flotation is a process that relies heavily on surface chemistry, 
 by adding all of the collectors to the conditioner, a thick, scummy and uncontrollable froth is obtained which yields a low and unmarketable grade concentrate with entrained insoluble minerals. Therefore careful consideration should be taken when selecting reagent-dosing points in the plant so that recovery and grade are optimized.

-When trialing additional or different collectors maintain a visual inspection history of the froth and concentrate in each circuit.


- Data from each shift should be collected over the duration of the trial so that shift recoveries and grades can be determined and to ascertain whether the trial collector is better or worse than the incumbent collector.
