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.

The sand is then mixed along with water in a specified ratio using a slurry pump and it is fed into the classifier through a feed inlet provided below the dewatering screen. As a result, the material enters the trough through a non-turbulent section of the bucket classifier. ... Copper Ore . Manganese Ore . Iron Ore ... 2022 Nesans Mining and ...

In production, many concentrators more or less encountered spiral classifier classification efficiency significantly reduced problem, The root cause of this problem is that fine and heavy ore particles and coarse and light ore particles in the process of classification settlement disorder, resulting in the phenomenon of equal fall, so that a large number of grader …

If the oxidation rate in copper-cobalt minerals is high, the semi-autogenous grinding (i.e. semi-autogenous grinding + ball grinding) process solution can be used. The cobalt ore beneficiation equipment used in this stage is mainly crushers, belt conveyors, vibrating screens, ball mills, and classifiers. Overflow ball mill; Grid type ball mill
