good magnetic separators for nickel laterite ore Nickel Laterites: The World's Largest Source of Nickel .... Nov 21, 2019· Nickel is found in two types of deposits; magnetic separator for nickel ore - studiotundo. Magnetic separation of the reduced products was conducted using a... WO2014133421A1 -
May 20, 2012 · Selective reduction and magnetic separation was conducted on low grade nickel laterite ore. High grade nickeliferous concentrate could be produced from these laterite ores. The addition of calcium sulphate promoted nickel concentration. Nickel was mainly concentrated into a γ Fe–Ni phase in the reduced ore. Calcium sulphate improved the growth of γ Fe–Ni phase
Mar 01, 2020 · Abstract. The process of deep reduction and magnetic separation was proposed to enrich nickel and iron from laterite nickel ores. Results show that nickel–iron concentrates with nickel grade of 6.96%, nickel recovery of 94.06%, iron grade of 34.74%, and iron recovery of 80.44% could be obtained after magnetic separation under the conditions of reduction temperature of 1275 °C, reduction time of …
Oct 03, 2014 · Abstract. Ferronickel enrichment and extraction from nickel laterite ore were studied through reduction and magnetic separation. Reduction experiments were performed using hydrogen and carbon monoxide as reductants at different temperatures (700–1000°C). Magnetic separation of the reduced products was conducted using a SLon-100 cycle pulsating magnetic separator (1.2 T)
Jan 28, 2016 · FERRO NICKEL ORE- A recent development in the extraction of nickel laterite ores is a particular grade of tropical deposits, typified by examples at Acoje in the Philippines. This ore is so rich in limonite (generally grading 47% to 59% iron, 0.8 to 1.5% nickel and trace cobalt) that it is essentially similar to low-grade iron ore
Apr 01, 2002 · The laterite nickel ore at Goro is composed of two layers–limonite and saprolite–between a cover of leached material and the bedrock below. The 10-20-m-thick cover has its own two layers: brittle iron oxide crust covers a high-hematite zone. Beneath these is the 10-m …
Mar 20, 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
Nickel processing - Nickel processing - Extraction and refining: 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 higher operating temperatures in nickel
The optimum condition in this selective reduction process was obtained with the addition of 5 wt. % of reductant and 10 wt. % of sodium sulfate in nickel ore, which was reduced at 1150oC for 60 minutes. It resulted in 4.60% and 73.23% for nickel grade and its recovery, respectively. Add to Cart
