Thickening

thickener with minimum turbulence and uniform distribution while dissipating most of its kinetic energy. Feed slurry enters the feed well, which is usually located in the centre of the thickener, through a pipe or launder suspended from the bridge. To avoid excess velocity, an open launder normally has a slope no greater than 2/100. Pulp should enter the launder, suspended from the bridge, at

Gold Ore Processing Decantation Tanks

Counter Current Decantation. The loss in dissolved gold per ton of dry ore for the last tank has, therefore, been plotted in a separate curve, and it is this curve which should be given the most serious attention in determining the suitability of an ore for decantation. The moisture in the pulp also has a direct bearing on the cyanide loss, which is also shown in Fig. 5. Cyanidation carbon in

definition of mineral thickeners

2020-06-20 A thickening agent or thickener is a substance which can increase the viscosity of a liquid without substantially changing its other properties. Edible thickeners are commonly used to thicken sauces, soups, and puddings without altering their taste; thickeners are also used in paints, inks, explosives, and cosmetics.. Thickeners may also improve the suspension of other ingredients

thickener operation in water purification

Thickener EKCP. thickener tank EIMCO KCP Thickener tanks are constructed either from bolted / steel welded or concrete. Most of the stone process industries prefer the steel tanks construction since they may be elevated above ground level, allow inspection of the tank's floor for leakages and bring the underflow slurry pumps nearer to the outlet of the discharge cone.

Counter Current Decantation Design Formula

The overflow from the first thickener of the Counter Current Decantation series containing the greatest amount of dissolved metal is sent to precipitation or to the grinding and classifying circuit. The underflow is pumped to the next thickener, diluted with the overflow from the third of the series, settled and thus proceeds through each thickener, until discharged from the last as tailings

Design and selection of separation processes

the separation of heterogeneous liquid-liquid emulsions is decantation or hydrocyclones. For gas-solid and gas-liquid separation (i.e. gas cleaning), gravity settling, centrifugation, filtering, washing, and electrostatic precipitation may be used. The need to separate solid and liquid phases (i.e. suspension) is probably the most common separation requirement in the process industries, and
