A composition and method for agglomerating/coagulating silica particles in aqueous mineral process streams comprising polyalkylene glycols and non-salt polyether amines and further contacting with flocculant agent. The invention further discloses removing agglomerated silica particles from aqueous mineral processing stream by combination of filtering, flocculating and settling operations. Preferred polyalkylene glycols are: Polyethylene glycol (PEG) Preferred non-salt polyether amines are: Formula (I): Polyether monoamine Where R1 is any combination of H or CH3, R2 is CH3 or H, and n is an integer > 1. Formula (II): Polyether diamine Where R3 is any combination of H or CH3, R4 is CH3 or H, and m is integer > 1. |
