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.

Xanthates	Relative Strength	Typical Plant Concentration %
Sodium Ethyl Xanthate /SEX	WEAK	10-20
Sodium Isopropyl Xanthate /SIPX	↓ STRONG	10.20
Sodium Isobutyl Xanthate /SIBX		10-20
Potassium Amyl Xanthate /PAX		15-25

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.

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