extraction ofnickelfrom garnierite lateriteoreusing

Ferronickel concentrate with Ni of 16.16%, Fe of 73.67%, and nickel recovery of 90.33% was obtained under the comprehensive conditions used: A roasting temperature of 1100 °C, a roasting time of 90 min, a calcium chloride dosage of 15%, an iron concentrate dosage of 30%, a coke dosage of 15%, a coke size of −1 + 0.5 mm, a magnetic separation grinding fineness of <45 μm occupying 90%, and a magnetic …

nickel oreprocessingmagnetic separation

1/11/2020 The magnetic separation efficiency of nickel from the laterite ore was evaluated using the recovery ratio of nickel R ni using the formula: (1) R Ni = m Ni × β Ni M Ni × γ Ni × 100 % where m Ni is the mass of the magnetic product, g; β Ni is the nickel content inM

extraction of nickel|nickel oremining | mining

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

pre-concentration of nickel in lateriteores using

Sep 01, 2019 · Nickel is upgraded by 17% and 36% for ore S and I, respectively. There is no change in the nickel grade of ore L using the Falcon, similarly to what was obtained using the magnetic separation. The XRD analysis of the light fraction of the Falcon concentrator for the ore S and I samples is presented in Fig. 4. It seems that both particle size and particle density are affecting the separation using the …

Nov 01, 2020 · The magnetic separation efficiency of nickel from the laterite ore was evaluated using the recovery ratio of nickel R ni using the formula: (1) R Ni = m Ni × β Ni M Ni × γ Ni × 100 % where m Ni is the mass of the magnetic product, g; β Ni is the nickel content in the magnetic product, wt.%; M Ni is the mass of the reduction product, g; and γ Ni is the nickel content in the reduced laterite ore, wt.%

ferronickel enrichment by fine particlereduction and

Magnetic separation of the reduced products was conducted using a SLon-100 cycle pulsating magnetic separator (1.2 T). Composition analysis indicates that the nickel laterite ore contains a total iron content of 22.50wt% and a total nickel content of 1.91wt%. Its mineral composition mainly consists of serpentine, hortonolite, and goethite

magnetic separationfor mining industry magnetense

Global Fourth-generation Vertical Ring High Gradient Magnetic separator (Oil-water complound cooling) Application: This type of magnetic separation machine is used in wet separation processes for smaller than 1,2 mm ( – 200 mesh of 30-100 %) of fine grained red mine (hematite) limonite, manganese ore, ilmenite and some kinds of weakly magnetic minerals like quartz, feldspar, nepheline ore

(pdf)chloridization and reduction roasting ofhigh

The current pyrometallurgical methods have been exploited for processing nickel metal from low-grade laterite ore, such as in the metallic reduction roasting-magnetic separation process (Krupp

the beneficiation process ofnickel ore,copper-nickel

The beneficiation process of nickel ore . Nickel ore is mainly divided into copper-nickel sulfide ore and nickel oxide ore, and their beneficiation and processing methods are completely different. The main method for beneficiation of copper-nickel sulfide ore is flotation, while magnetic separation and gravity separation are usually auxiliary beneficiation methods. When flotation of copper sulfide nickel ores, …

the value of mineralogical analyses for base metal mining

Historically most nickel production was derived from sulphide deposits due to the lower cost of processing, compared to laterite ores. However, today laterite nickel ore became an important second source of nickel production, next to the sulphide deposits. Mined sulfide ore, after crushing and grinding, is concentrated using flotation and magnetic separation

mechanism of sodium chloride in promoting reduction of

Jul 04, 2016 · In the absence of moisture, the magnetic separation results show that the recoveries of iron and nickel have a significant increase; moreover, olivine structure would be …

chloridization and reduction roasting of high-magnesium

Oct 15, 2015 · The chloridization and reduction roasting of high-magnesium, low-nickel oxide ore containing 0.82 pct Ni and 31.49 pct MgO were investigated in this study. Mineralogical investigation indicated that 84.6 pct of nickel was associated with silicates, and nickel was well distributed in mineral in the form of isomorphism
