What is Potassium isopentyl dithiocarbonate?

Potassium isopentyl dithiocarbonate (CAS 928-70-1) is a xanthate-class collector used in the froth flotation of sulfide ores.

Copper, lead and zinc sulfide flotation: promotes selective mineral attachment to air bubbles, improving concentrate grade and recovery
Polymetallic ore processing: longer-chain xanthate for less-reactive sulfide surfaces
Gold-bearing sulfide circuits: collector performance affects downstream leaching and smelting economics
Blending with shorter-chain xanthates or other collectors fine-tunes selectivity against iron sulfide gangue such as pyrite.
It selectively adsorbs onto mineral surfaces, enabling separation and concentration of target metal sulfides from gangue.
