  • How to Size a Thickener Mineral Processing & Metallurgy

    Knowing how to size a thickener and determine the capacity required to handle a pre-determined tonnage of a certain pulp, by overflowing a clear solution and obtaining the desired pulp density of thickener discharge, depends upon the settling rate of that particular pulp. The settling rate of any pulp is easily determined by simple laboratory tests such as outlined below: Laboratory Test

    The AMIRA P266 'Improving Thickener Technology' series of projects has sought to provide a firm scientific basis for feedwell and thickener design, a requirement as pressures on water usage in the

  • High-rate Thickener |

    EIMCO and Dorr-Oliver thickeners are available in both bridge-supported and column-supported designs. We offer beam- or truss-type bridges, depending on thickener diameter. In the bridge-supported design, suitable for thickeners up to 50 m in diameter, the drive is supported by the bridge, driving the rakes with a centre shaft.. Column-supported design drives are supported by a stationary

    Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%.

  • Thickening and clarifying

    Combined with our E-Volute feedwell, this results in the lowest flocculant usage of any thickener supplier. We also have led the way in developing paste thickening technology, with more paste thickening installations than all of our competitors combined. All of the durable and productive thickening and clarifying equipment we offer is among the most technologically advanced and rigorously

  • Thickening Resource Book

    The basic design of a high rate thickener is below. High rate thickener feed wells are designed to disperse flocculants thoroughly into the feed end to admit the flocculated slurry into the settling zone of the thickener without destruction of the newly formed floccules. The feed may enter into the sludge bed if the flocculation must be completed by the solids-contact means, or it may enter

  • A Critical Review of Thickener Design Methods t

We distinguish three types of methods: those based on macroscopic balances, those based on kinematic models and those based on dynamic models. This classification permits the analysis of thickener design proce­ dures with a clear perspective of their applicability and limitations. 1. Introduction: Definition, equipments and operation
