Sep 17, 2018 In this study, the usability of cyclones in the beneficiation of tailings of a coal preparation plant was investigated. For this purpose, separation tests were conducted using spiral concentrator and heavy medium cyclones with the specific weight of medium 1.3–1.8 (g/cm3) on different grading fractions of tailing in an industrial scale (the weight of tail sample was five tons)
Figure 4 displays the exposure of copper sulphides within copper sulphide bearing particles in the Concentrator 1 tailings stream. In the coarsest fraction above 150 µm, exposure of copper sulphides is low with most particles having the lowest sulphide exposure (<10% ) where recovery via the existing flotation circuit is poorest at only 30%.
Later, the concentrator of the copper mine listened to the suggestion of sinonine technical group and adopted a system composed of thickener, cyclone and dewatering screen for dry discharge of tailings. The system can meet the dewatering requirement of 80% of - 325 mesh, and the final water content of tailings slurry is about 15%.

The processing facility at the Kolwezi Tailings project, which is approximately 75% complete, is expected to be transferred to ENRC at closing. The Kolwezi Tailings project consists of a tailings dam, with mineral reserve of 1.7 million tonnes of copper and 363 thousand tonnes of cobalt, grading 1.49% and 0.32% respectively.
Cyclone separator, or water scrubber, electrostatic precipitator and bag-house filter system.Dry cyclone separator can remove up to 100 micron size particles. But particles smaller than this escape. Dust loading in the flue of a FBC is of the order 50–75 g/m 3.Present author found through improvised experiments that incorporation of a water scrubber after the cyclone effectively removes all ...
The final concentrator tailings (combined bulk rougher plus bulk cleaner/scavenger tailings products), at approximately 28% solids, will flow by gravity from the concen trator flotation area via a lined launder to the tailings thickener distributor box. The tailings thickening area has two 85 m diameter, high – rate tailings thickeners.
The plant produces copper cathodes from concentrator tailings and reclaimed tailings. The process was initially based on the acid leach–cementation process. However, the advent of the solvent extraction technology led to the plant being upgraded in 1973/1974 which greatly increased the utility of hydrometallurgy in the extraction of copper ...
Cyclone separators can be installed as single units, or in multiples, known as multi-cyclones. It is also possible to install cyclones in series, or, in parallel. Separators can be installed with a horizontal or vertical orientation. Gas Cyclone Separators . Gas cyclone separators are grouped into two main categories, reverse-flow and axial-flow.

An important consideration in any recycle stream scenario is the impact of components of the stream on upstream unit process, as well as the buildup of aqueous concentrations in these streams. Of particular concern is cyanide and its reaction products, both from an economic aspect and potential impact on unit efficiencies.

In extreme cases the ratio of grade between cyclone underflow and overflow can be >50. Placing a concentrator on cyclone underflow maximizes the precious metal units that the enhanced gravity concentration equipment sees per unit of feed. For a long time it has been assumed that cyclone underflow will consequently have the highest output of metal.
The cyclone underflow from each line reports to a ball mill, while the cyclone overflow is directed to the flotation circuit. The designed ball milling circuit product is 80% passing 150 µm. Several large tonnage copper porphyry plants in Chile use an open-circuit SAG configuration where the pebble crusher product is directed to the ball mills ...
