flocculants in dewatering in mineral processing

Flocculation and dewatering ScienceDirect

Dewatering, of concentrates, tailings, etc., is an important ancillary process in most mineral processing operations. Improperly designed and/or operated dewatering systems can become limiting factors in plant operation or capacity. Typically, final dewatering is accomplished by sedimentation or filtration and, in some cases, both. Flocculation

Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue

The dewatering continues in the pits, and a solids content of 30% to 40% is reached in a few weeks, as reported by Gardinier. After this dewatering,more thickened clay-sand tailings will be placed in the pit in stages, to allow each addition to dewater before more is added. After approximately 1 yr, the sand-clay mixture in the pits will be

Flocculation in Mineral Processing SpringerLink

Abstract. Flocculation is a characteristic property of colloidal dispersions. The typical classical sol contained sub-microscopic dispersed particles which would pass freely through ordinary filter-paper, and were too small to be resolved by any transmission optical microscope. Consequently, an arbitrary size limit of 0.1 μm could be defined as the upper size boundary of the colloidal range.
