All the flotation test-work was done using the Denver laboratory machine with a 1.5l stainless steel flotation cell. The required mass of nickel-copper sulphide ore material ground to 70% passing 75 µm was weighed and placed in the flotation cell. This was followed by the addition of distilled water to about
Mineralogy is the driving force behind flotation performance. A flotation batch and rate test measures this as mass pull recovery and concentrate grade. The real data from a rate test can be processed to determine the flotation kinetics of metal, mineral and gangue. What we cover here is what are kinetics and what do they mean. ...

We proceeded from the amount of reagents (xanthate—170 g/ton, aerofloat—120 g/ton, sodium carbonate—2000 g/ton, copper sulphate—50 g/ton) consumed per 1 ton of the copper–nickel ore at a sulphide content of 10%. Flotation was conducted in a sodium carbonate solution with a small amount of copper sulphate (pulp …
16.1 ORE TYPES AND MINERALOGY. There are more than 45 different nickel minerals, but only a few are of economic importance. Table 16.1 lists some of the most important nickel minerals. Nickel, in various ores can also be found in other minerals, such as pyrrhotite and various cobalt minerals as an exsolution in isomorphic phases.
Transferring non-sulphide gangue (rock) from the copper to nickel concentrates would reduce smelter costs. To investigate if installation of new flotation equipment could be justified to improve copper/nickel separation, three pilot plants were run in parallel to the plant operation: . 2. . A column pilot plant with a flexible three stage ...
Flotation machines are essential for recovering metal minerals and are used to separate metals including copper, lead, zinc, nickel, molybdenum, gold, and silver. They are also used for the beneficiation of metal ore. ... Processing of Non-Metallic Minerals: Flotation equipment is widely used in the processing of non-metallic minerals such ...

The cyclonic microbubble flotation column is an efficient separation equipment in the beneficiation process of metallic and non-metallic minerals. However, the higher detachment rate of coarse particles in the pulp, pulp-froth interfacial zone, and froth zone is an issue that needs to be addressed urgently in column flotation.
Abstract. Rare earth elements (REEs) are irreplaceable materials supporting low-carbon technology and equipment, and their commercial demand and strategic position are becoming increasingly prominent. With the continuous depletion of rare earth (RE) resources, developing high-efficiency beneficiation and eco-friendly metallurgical …

Flotation practice differs by geographical location. Bulk sulfide flotation is generally carried out on Western Australian nickel ores which tend to be low in copper and contain substantial ...
Heavy metal contaminated waters are a significant environmental hazard, which require novel treatment methodologies. Further, the metals which might be recovered from these streams have significant intrinsic value, if they can be collected and concentrated. This work demonstrates, for the first time, the use of surfactin, an …
The flotation by surface sulphidisation of the oxidized copper-cobalt-bearing ore from Kimpe (1.97% Cu; 0.66% Co) was studied in order to evaluate its behavior by the analysis of its most ...
A Copper Flotation Flowsheet. Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation. In general most operations of this type have two or more …

When analyzing copper-nickel ore, if the copper content in the ore is much higher than that of nickel, the direct or partial preferential flotation process can be used. After crushing, screening, grinding and classification, the raw ore enters the flotation machine for preferential flotation. After flotation, copper concentrate can be obtained.
