Floatation agent that improves flocculation and recovery ores in mining
In Explosives Industry: Water proofing, thickening and foam stabilizing properties are
required in the preparation of explosives. Slurry explosives are generally based on
various concentrated (60-80%) suspensions or solutions of nitrate salts; therefore gum
to be employed must be compatible with high-level of salts.
Oxidized guar gum are the most commonly used polysaccharides to thicken slurry explosives.
In the production of water-resisting ammonium nitrate stick explosive, guar gum is used as a binding agent.
When the explosive stick is immersed in water, the oxidized gum in the outer wall swells rapidly and the resultant gel retards leaching of the salts.
It is also used as a thickener and gelling agent for slurry explosive.
