Guar Gum (Mining Grade Flocculant)
CAS Number: 9000-30-0
Guar Gum is a natural polysaccharide flocculant and depressant derived from guar beans, used in mineral processing for selective depression of talc and other sheet silicate gangue minerals in sulfide flotation. It is also employed as a natural flocculant for tailings slurries where biodegradable reagents are preferred. Guar Gum performs effectively at low temperatures and under alkaline conditions typical in metallic ore flotation circuits.
