⚙️ Potassium Ethyl Xanthate (PEX) – Collector for Sulfide Mineral Flotation
Potassium Ethyl Xanthate (PEX) is a widely used xanthate-class flotation reagent, commonly applied as a collector in the beneficiation of sulfide ores, including copper, lead, zinc, and gold. With strong collecting ability and good selectivity, PEX is effective in the flotation of both simple and complex ores, especially where a moderate collector strength is required.
PEX is suitable for use in neutral or alkaline circuits and is available in powder or pellet form, packed for international industrial use under regulated safety standards.
✅ Key Features & Benefits
-
🧲 Moderate Collector Strength
Ideal for flotation of sulfide minerals where gentler selectivity is needed. -
⚡ High Efficiency in Sulfide Ore Flotation
Used in lead-zinc, copper, and gold ore flotation, especially in combination with other reagents. -
🌊 Effective in Neutral to Alkaline pH
Performs consistently in common circuit pH ranges. -
🔁 Compatible with Mixed Collector Systems
Can be combined with stronger xanthates (e.g., PAX, SIPX) to optimize selectivity and recovery. -
🔒 Stable Shelf Life & Easy Transport
Packaged to prevent degradation and moisture contact.
🏭 Common Applications
-
Lead-zinc ore flotation
-
Copper ore flotation
-
Gold beneficiation in polymetallic ore systems
-
Selective flotation of sulfide minerals in medium to low-grade ores
