The flotation and DAF treatment tests were carried out at Boliden's Kevitsa concentrator plant. Kevitsa is a low-grade Ni-Cu-PGE deposit, where nickel is carried mainly by pentlandite and copper by chalcopyrite. Platinum group metals are mainly associated with nickel minerals, while gold reports to the copper concentrate.
The process method is to extract copper and nickel minerals by mixing and flotation from the ore, and then separately select copper concentrate (containing low nickel) ore and nickel (containing low copper) concentrate from the mixed concentrate. The obtained nickel concentrate can be directly smelted. (1).
2. Mixed Flotation. The mix flotation process is suitable for separating the ore that is a copper grade lower than nickel. The concentrate with copper and nickel will be smelted into high-grade nickel matte. 3. Mixed–priority Flotation. Mix-flotation the copper-nickel from the ore, then separate the low-grade nickel and low-grade copper ...
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 …
The flotation machine is composed of single or multiple flotation cells, by agitating and inflating the chemical reagent treated slurry, some mineral ore particles are adhered to the and float up, and then be scraped out, while the rest remains in the slurry. Types of flotation machine

Nickel Ore Processing Plant Star Trace offers turnkey solutions for nickel ore processing plants. We are one of the leading project suppliers for nickel ore plants and we work closely with our customers to fulfill their specific needs for a customized packaged solution.
Nickel ore processing usually needs to go through three processes: crushing – screening- grinding- flotation separation- drying, and magnetic separation and gravity separation are usually auxiliary beneficiation methods. 1. Crushing and screening: The feeder sends the mined raw ore to the jaw crusher for coarse crushing.
Before starting the laboratory flotation test, process water pH was adjusted to 9.5 by lime addition. All tests were carried out at a temperature of 20 °C. Prior to flotation, the test feed batch was ground in a laboratory mill at 70% solids for 27 min. The tests were performed using an Outotec GTK LabCell flotation machine with a 2 L ...
The flotation procedure used was to condition 600 grams of ground ore pulp for 3 min, using collector at the rate of 0.1 lb/ton; add 1 drop of MIBC, condition for 1 min; and then float (5 min) to produce a …
The aim of the present work was to perform copper, nickel, and platinum group metals (PGMs) recovery from low-grade copper–nickel concentrate containing pyrrhotite, pentlandite, and chalcopyrite by bioleaching in stirred tank reactors in batch mode and subsequent cyanidation. The concentrate contained (%) Fe 32.7, Cu 0.7, Ni 2.3, Stotal …

The mixed flotation process is a commonly used process in the flotation of polymetallic sulfide ores. First, all the useful minerals are mixed and floated, and then the useful minerals in the mixed concentrate are separated one by one. This process is suitable for useful minerals grade comparison. Low (more gangue content) and useful minerals ...

Pump the ore pulp into the agitation tank, add the sulfide inhibitor and copper collector, send the mixture into the flotation machine to get copper concentrate and nickel-bearing tailings. The nickel-containing tailings go through flotation to obtain nickel concentrate or copper-nickel concentrate. Copper-nickel mixed flotation
BENCH-SCALE mineral species in the ore at a set (pre-FLOTATION TESTS Geometallurgical modelling can be defined as an approach that measures metallurgical variability within an ore body and quantifies the effect of this variability on the comminution and metallurgical response of the ore, as it pertains to full-scale production.
