Isopropyl xanthate

Isopropyl xanthate (CAS 108-25-8), also known as Proxan, is a xanthate collector used in the selective flotation of sulfide ores.

Where is Isopropyl xanthate used?

• Copper, lead and zinc sulfide processing: primary collector to concentrate target minerals
• Gold and silver recovery: floats sulfide-associated precious metals
• Nickel and molybdenum concentrators: controlled collecting power for grade-recovery balance
• Complex polymetallic ore circuits: collector addition alongside selective depression of non-target sulfides
• It adsorbs onto mineral surfaces to render them hydrophobic.

Commercial specifications

• 25 kg bags and bulk quantities
