Potassium Butyl Xanthate (PBX 90%) is a reagent that plays a pivotal role in modern mining and metallurgy.

Potassium Butyl Xanthate (PBX 90%) is an indispensable ally in the flotation process, a cornerstone of mineral extraction. Flotation involves separating desired minerals from their ores.

Potassium Butyl Xanthate (PBX) acts as an important collector in the flotation of sulfide ores. Mining companies commonly use PBX in concentrations of 85% and 90%.

Flotation Process

Selective Adhesion: When operators introduce PBX into a slurry of finely ground ore and water, the chemical selectively attaches to the surfaces of sulfide minerals. These minerals often contain valuable metals such as copper or lead and have a strong affinity for xanthate collectors.

Bubble Attachment: Operators introduce air bubbles into the slurry. The hydrophobic mineral particles attach to the air bubbles.

Rising to the Surface: The mineral-laden bubbles rise to the surface of the flotation cell and form a froth layer. Operators then skim the froth from the surface to recover the target minerals as concentrate.

Potassium Butyl Xanthate typically appears as a light-yellow powder or pellets and has a strong odor. It dissolves readily in water and can decompose when exposed to acids or excessive heat.

PBX functions as a powerful and selective collector. Mining companies widely use it in the flotation of sulfide ores, including zinc and nickel ores, particularly when they need to selectively recover valuable sulfide minerals.
