magnetic separator for nickel ore - studiotundo. Magnetic separation of the reduced products was conducted using a SLon-100 cycle pulsating magnetic separator (12 T) Composition analysis indicates that the nickel laterite ore contains a total iron content of 2250wt% and a total nickel content of 191wt% Its mineral composition mainly consists of serpentine, hortonolite, and goethite.
In the present work, magnetic separation of the low grade (∼1%), goethite-rich Ni laterite ores was investigated. Samples of 1 kg mass were ground down to -50 m and two different intensities (0.12 and 0.25T) of dry magnetic separators were used at ambient temperature. Table 3 shows the amount of magnetic material and nickel content in each ...
The method comprises the following steps of 1) crushing and grinding waste residues of reduction roasting the nickel laterite ore to prepare ferronickel, and then carrying out magnetic separation to obtain a Ni-rich magnetic concentrate and a Cr-rich magnetic tailing; 2) wet-grinding the Cr-rich magnetic tailing, dry mixing a solid alkali and ...
Mar 24, 2021 Generally, like other ore beneficiaiton plants, laterite nickel ore processing needs several stages includes ore washing, crushing and screening, milling by ball mill, magnetic and froth flotation separating and drying and melting. The distribution of useful mineral nickel varies with the nature of the ore.
Froth flotation process is the main mineral processing method used in the extraction of copper-nickel sulfide ore, while the magnetic separation process and gravity separation process are usually used as the auxiliary mineral processing methods.

Oct 16, 2019 Extraction of Nickel. This paper introduces the extraction of nickel process and characteristics of laterite nickel ore dressing, highlights the nickel ore crushing, washing in the nickel production process design.. 1 Description of nickel ore. The laterite nickel ore is complex in composition and can be roughly divided into two types: limonite type and silicon magnesium-nickel type.
Magnetic Separator Minerali Industriali. The objective of the invention is to overcome above-mentioned not enough problem, a kind of andalusite ore strong magnetic-heavy media separation technique is provided, technology is simple to operation, and the products therefrom quality is good, concentrate yield and rate of recovery height.

Lateritic ore is mixed with a chloridizing agent and a carbonaceous reductant to form an ore mixture for segregation roasting. The ore mixture is roasted at a temperature in the range of 1600*-2000*F. for a time duration of 0.5 to 2 hours in the presence of a reducing atmosphere provided by a mixture of CO-CO2 or H2-H2O gases to form a calcine containing nickel alloyed with iron.
[Introduction] : A wet permanent magnetic separator for separating strong magnetic minerals [Capacity] : 24t/h-240t/h [Improvement] : Magnetic system materials adopt the NdFeB with high magnetic energy product and high coercivity, strong magnetic density and high affect depth; the surface of the cylinder is lined with Xinhai wear-resistant rubber.
magnetic separation. Jiang 21) have recovered nickel et al. from laterite ore (Ni: 1.5 mass%, T Fe: 34.7 mass%) by selective reduction with addition of sodium sulfate (10.0 mass%) at 1 200 C for 50 min. A ferronickel concentrate with Ni grade of 9.9 mass% and nickel recovery of 90.9% was obtained after wet magnetic separation. Lu 14) et al.
