The depressing effect, however, is so much more pronounced on the zinc and iron than on the copper minerals that a reasonable recovery of the latter is usually possible. The lead-copper concentrate is cleaned if necessary, diluted to a suitable pulp density, and treated in a conditioner with sodium cyanide in sufficient strength to depress the ...

A hydrocyclone is a simple cone-shaped cylindrical container that has no moving parts. It is used to separate or "cut" solid particles in a liquid stream by size and density. What does a hydrocyclone look like? A hydrocyclone consists of a cylindrical top with an offset feed inlet pipe, an overflow outlet on top and tapered cone(s) leading ...

The zinc is mainly in the forms of ZnFe 2 O 4 and ZnO in EAFD [8].Many pyrometallurgical and hydrometallurgical methods were developed to extract zinc from EAFD. The pyrometallurgical methods consist in taking EAFD at high temperature to volatilize zinc as a gas, and then obtain zinc metal or zinc oxide by cooling [9], [10].The Waelz kiln mehod is one of the …

Due to this complexity many authors have produced correlations for both the separation efficiency and the pressure drop in hydrocyclones. Reviews have been published by Bradley (1965) and Svarovsky (1984). The centrifugal force that is generated is capable of separating particulate solids down to around 5 to 10 microns in size.

If this is the case, removal of the finest size fraction will increase the total iron grade of the hydrocyclone underflow stream. To understand the behaviour of fine iron ores in hydrocyclone processing and to reliably predict such behaviour, a large amount of information about the ore needs to be obtained (Clout et al. 1998, Donskoi et al. 2005a).
