After a semi-industrial test of cyclone recovery of copper and gold in tailings, a short-cone hydrocyclone was used to enrich the total tailings once, then it can get similar grit of the original ore. The yield of test tailings was 9%, the copper grade was 0.18% -0.25%, the gold grade was 0.08- 0.16g / t, and the enrichment ratio is 2.8 times.
Hydrocyclone is a grading device that uses centrifugal force to accelerate ore particle deposition. It needs the pressure to feed ore, so it consumes a lot of power but occupies a small area, cheap, the processing capacity is large, The classification efficiency is high, obtain very fine overflow product, mostly used in the second stage of closed-circuit grinding …
To the best of authors' knowledge, although the first patent on the hydrocyclone is about 128 years old, to date, there are just a few reviews on hydrocyclones (Table 1), and marginal effort has been attempted to comprehensively review and summarize enhanced-separation hydrocyclone technologies developed by optimizing operating parameters and …
In developing and utilizing copper ore resources, ... The classification equipment of copper ore concentrators mainly includes spiral classifiers and hydrocyclone. The spiral classifier is primarily used for closed-circuit operation with ore grinding equipment or ore washing, dehydration, desliming, etc., and has a better classification effect ...

The hydrocyclone is a simple piece of equipment that uses fluid pressure to generate centrifugal force and a flow pattern which can separate particles or droplets from a liquid medium. These particles or droplets must have a sufficiently different density relative to the medium in order to achieve separation.It is a high technological enterprise that integrated research, manufacture, …
The new 2 hydrocyclone delivers a boost to separation technology, with its LIG+ advanced laminar spiral inlet and size of the feed chamber, ... The testing was conducted in a large copper ore mine which had a SAG mill in a closed circuit with the cyclone cluster. The trial tested one 2 650 in a 6-place cluster of existing ...
The evaluations implied that air classification operation resulted in less bypass value than that of hydrocyclone. For the copper ore, gold ore and mag-cal blend, bypass of hydrocyclone was around 31 %, 15 % and 55 % respectively whereas air classifier had 13 %, 19 % and 26 % respectively. The sharpness of separations of the two units were ...

A spiral classifier and a hydrocyclone are the two main classification equipment. For decades, the spiral classifier has been widely used in ore dressing plants as first-generation grading equipment. As second-generation grading equipment, hydrocyclones quickly occupy a place in the grading equipment of the concentrator due to their small footprint and high …
presented. Fast flotation of coal, oil shale, and copper porphyry ore has been demonstrated with capacities far exceeding those of conventional flotation cells. In addition to the performance characteristics of the air-sparged hydrocyclone, fluid-flow phenomena are reviewed and cost-analysis data are summarized. INTRODUCTION
The 900 mm hydrocyclone can also produce an increase in the amount of +150 micron material reporting to the hydrocyclone overflow, and a decrease in the amount of -75 micron material in the cyclone underflow product. If the smaller hydrocyclone diameter is used, the total solids recovery of material to the hydrocyclone underflow would be higher.
Apex and vortex finder diameters of hydrocyclone are 140 mm and 200 mm, respectively. A belt conveyor and water replenishment feed the copper ore with particle size d80 of 10 mm into the ball mill. The coarse copper's ore size reduces due to the interactions between copper ore and steel balls during the ball mill's rotation.

Copper industrial minerals include: natural copper, chalcopyrite, chalcocite, tetrahedrite, azurite, malachite, etc. Chalcopyrite (a compound of copper, sulfur, and iron) is mined mainly, followed by chalcocite and bornite. If copper ore wants to be fully utilized, it must be processed by flotation. Flotation separation is an important copper ore beneficiation process in …

A series of tests on a 24 inch hydrocyclone operating on a copper ore slurry were run. The ore was selected so as to be reasonably homogeneous with regard to the density of components so that particle size differences dominate the classifier action. The primary variables were % solids (and associated viscosity readings), the feed rate of slurry ...
