Potassium Amyl Xanthate (PAX)
CAS Number: 2720-73-2
Potassium Amyl Xanthate (PAX) is a strong collector for sulfide ores, particularly effective in copper, lead, and zinc flotation operations. Its longer carbon chain compared to shorter xanthates imparts greater collecting power and improved froth stability, making it suitable for processing lower-grade and complex sulfide ores. PAX is widely employed in selective flotation circuits requiring high metal recovery.
