Xanthates, such as the ones manufactured at Prospec Chemicals, are the most commonly used sulfide collectors in the mining industry today. A list of these can be found below.
The strength of our Xanthates is based on the alcohol chain attached to the Xanthate molecule with ethyl (2-carbons) being the weakest and amyl (5-carbons) being the strongest. KAX 20,
Potassium Ethyl Xanthate, is very selective in nature while KAX 55, Potassium N-Amyl Xanthate, is a non-selective collector.
Available in pellet or powder form, but also liquid to customers with close proximity to our plant at Fort Saskatchewan, Alberta, Canada, our Xanthates are shipped in a varity of packaging from 155 kg open top drums to 500, 750 and 1000 kg Super Sacs.
Prospec Chemicals also offers Flexanthates, developed by TRTA. These are Xanthates enhanced with a proprietary surfactant to improve the attachment efficiency of the Xanthate molecules onto the sulfide surfaces.
