Quoted Price1. Introduction 1.1. Flocculation in hydrometallurgy The efficient solid–liquid separation of mineral suspensions is of critical importance to most hydrometallurgical processing operations. A variety of reagents may be added to slurries to enhance sedimentation by inducing aggregation.
Quoted PriceFlocculants, usually composed of PAMs, are widely used in several industrial fields, particularly in minerals extraction, to enhance solid/liquid separation in water containing suspended matter. These polymers can contain residual monomer of acrylamide (AMD), which is known to be a toxic compound.
Quoted Price1 Introduction Flocculants are long chain water soluble polymers used to separate non-settling fine solids (=particles) from aqueous suspensions.
