Pumping thickener underflow Mining WMFTG Mining

2022-1-3  Pumping thickener underflow. Many pump types struggle to meet the demand for pumping the high viscosity and high density mineral concentrate in thickener underflow transfer. Bredel hose pumps are designed to handle high-solids content fluids, such as concentrated ore paste with a solids content of 40-80%.

Thickening - Resource Book

2015-8-13  A thickener has several basic components: a tank to contain the slurry, feed piping and a feed well to allow the feed stream to enter the tank, a rotating rake mechanism to assist in moving the concentrated solids to the withdrawal points, an underflow solids withdrawal

Beginners guide to thickeners - Outotec

2017-6-16  Beginners guide to thickeners. Thickening is a process where a slurry or solid-liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water (or liquor in leaching processes). The driving force for the separation is gravitational, where the differences in phase densities drive the ...

Advanced thickener control - Outotec

2017-6-13  Philosophy. Typically, thickener controls are implemented as single loop controllers in DCS/PLC systems. These systems are challenged by long response dynamics and interaction between variables, leading to difficulties in maintaining underflow density. Underflow pumps and flocculant dosing pumps must be manipulated to control the thickener at ...

IMPLEMENTATION OF AN ADVANCED THICKENER

2017-10-10  The thickener underflow density is controlled by manipulating the flocculant addition and the thickener underflow flowrate. Thickener underflow density control using flocculant has a time delay due to the rate of reaction of the flocculant with the slurry which in-turn affects the settling rate of the solids, and thus the underflow slurry density.
