cyclonic separation is a method of removing particulates from an air, gas or liquid stream, without the use of filters, through vortex separation. when removing particulate matter from liquid, a hydrocyclone is used; while from gas, a gas cyclone is used. rotational effects and gravity are used to separate mixtures of solids and fluids. the method can also be used to separate fine droplets of liquid from a gaseous stream.
in tank leaching the ground, classified solids are already mixed with water to form a slurry or pulp, and this is pumped into the tanks. leaching reagents are added to the tanks to achieve the leaching reaction. in a continuous system the slurry will then either overflow from one tank to the next, or be pumped to the next tank.
however, although it is a form of liquid evaporation, it is quite different from flash evaporation. in spray drying, a slurry of very small solids is rapidly dried by suspension in a hot gas. the slurry is first atomized into very small liquid droplets which are then sprayed into a stream of hot dry air. the liquid rapidly evaporates leaving .
therefore, where site footprint constraints are of concern a lamella clarifier system is preferred. the reduced required area allows the possibility for the clarifiers to be located and operated inside, reducing some of the common problems of algae growth, clogging due to blowing debris accumulation and odour control, that occur when the .
a hydrocyclone is a device to classify, separate or sort particles in a liquid suspension based on the ratio of their centripetal force to fluid resistance. this ratio is high for dense and coarse particles, and low for light and fine particles. hydrocyclones also find application in the separation of liquids of different densities. a different description: a hydrocyclone is a mechanical device designed to reduce or increase the concentration of a dispersed phase, solid, liquid or gas of differe
in paste tailings the percent of solids in the tailings slurry is increased through the use of paste thickeners to produce a product where the minimal separation of water and solids occurs and the material is deposited into a storage area as a paste with a consistency somewhat like toothpaste . paste tailings has the advantage that more water .
