different levels was investigated. Therefore, the main objective of the study was to optimize the process parameters for the flotation of base metals from a nickel-copper sulphide ore. 2. Materials and Methods 2. 1. Materials The nickel-copper sulphide ore used in this study was supplied by Trojan Nickel Mine located in Bindura, Zimbabwe.
In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.
The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the …
of ore with 1.8% Ni and moisture 25% are needed. (75 000 tons dry ore x1.8%Ni = 1 350 tons Ni). This means 3 300 tons of ore per day is being processed (130 trucks of 25 tons each). 1 350 t nickel, that is 45 t nickel per day, are produced from this quantity of ore. However, our product is not only nickel, but an alloy made of 20%Ni and 80% Fe.
JXSC has developed a complete set of tin ore process plant equipment lines based on customer needs. The following is the specific process flow: 1. Washing stage: trommel scrubber. A loader or excavator feeds the materials into a hopper, and a drum washing machine (with 2mm and 10mm screens) cleans and screens the raw ore. 2.

The former adopts short-hole rock drill for nickel ore bodies with a thickness of less than 3-4m, and nickel ore is transported by electric rake or scraper to the stope orepass. The latter adopts medium- and deep-hole rock drill for ore bodies with a thickness of 5-30m, and nickel ore is transported by scraper onto the dump truck.
The concentrator will process ore using a conventional milling circuit. Unit operations include crushing, semi-autogenous and ball mill grinding, desliming, nickel flotation, magnetic separation on the flotation tailings and carbon storage using the Company's proprietary IPT Carbonation technology. The BFS

The leaching process results in an aqueous nickel and/or cobalt sulfate solution. This solution is further treated through iron, manganese, and other impurity-removal and solvent- ... reactors, …
4. Copper- Nickel Ore Flotation Process When process copper-sulfide nickel ore, collector and frothier will be used in order to better results. A basic principle of copper-sulfide nickel ore process is that it is better to let copper assimilate into nickel ore rather than the opposite. For it is easier to recovery cooper from nickel concentrate.
A certain copper-nickel ore is a large metal symbiotic copper-nickel sulfide ore.A suitable mineral processing process was designed for it, that is, the process flow of three—stage and one-closed-circuit ore crushing, stage grinding, copper-nickel mixing-separation flotation, three-stage dehydration of nickel concentrate, and two-stage ...
