dewatering in mineral processing

Mineral processing - Dewatering Britannica

Mineral processing - Mineral processing - Dewatering: Concentrates and tailings produced by the methods outlined above must be dewatered in order to convert the pulps to a transportable state. In addition, the water can be recycled into the existing water circuits of the processing plant, greatly reducing the demand for expensive fresh water.

Chapter 15. Dewatering - Wills' Mineral Processing ...

Dewatering. With few exceptions, most mineral-separation processes involve the use of substantial quantities of water and the final concentrate has to be separated from a pulp in which the water–solids ratio may be high. Dewatering, or solid–liquid separation, produces a relatively dry concentrate for

Optimization of dewatering systems for mineral

In this paper, we present a method for optimizing the design of dewatering systems that employ hydrocyclones and thickeners. Mathematical models were generated to determine the maximum water recovery rate and the corresponding system structure for given equipment sizes, and to determine the minimum cost of the equipment and the corresponding system structure for given water recovery rates.

Dewatering: An Increasingly Important Mineral

2020-4-8  McLanahan’s director of process engineering for mineral processing, Scott O’Brien, explained the rationale for using this approach to dewatering. O’Brien said while using a thickener on its own will enable an operator to recover 80%-90% of the water in a slurry, the underflow will still contain enough water to make it difficult to handle ...

2021-6-15  Dewatering in mineral processing is normally a combination of the above methods. The bulk of the water is first removed by sedimentation, or thickening, which produces a thickened pulp of perhaps 55 65% solids by weight. Up to 80% of the water can be separated at this stage. Filtration of the thick pulp then produces a moist filter cake of ...

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.
