Beneficiation of Low-Grade Laterite Nickel by Calcination

KEYWORDS: Phase transformation; Calcination; Nickel laterite; Magnetic separation. INTRODUCTION More than 70% of the world's nickel ores are laterites and about 30% of them are sulfides, but the majority of nickel production is from laterite reserves [1]. One big problem in the way of extracting nickel from laterites is an unequal distribution of nickel in the ore body [2]. On the other hand

laterite nickel ore calcination process

Since, the laterite ore usually contains Fe which has magnetic properties, the concentration of Ni is not an easy task. In order to enable the selective concentration of nickel by magnetic separation, the calcination of laterite was carried out prior to the magnetic separation.

Laterite ores are the major source of nickel (72 % of the reserves), much lower negative impact to environment and lower mining cost. But their contribution in the world's nickel production is only 42 % [3]. Industrial nickel production from laterite

Nickel | Geoscience Australia

The Earth's magnetic field is due to the iron and nickel in its core. Properties. Nickel is a hard silver-white metal with a high melting point and can withstand very low temperatures. Nickel is rarely found in the earth in its pure form; it mixes well with other metals to make many useful alloys. Nickel is malleable and ductile (can be beaten and drawn out into a wire) and is rust-resistant
