Upgrading low nickel content laterite ores using selective,
Abstract The processing of nickel laterite ore to produce ferronickel is energy intensive, especially when low nickel content ores are processed. The selective reduction–beneficiation of laterite ore to produce high nickel content nickeliferous concentrate and abandon gangue minerals before smelting potentially offers an effective pre-treatment to this process.
Evolution of ferronickel particles during the reduction of,
12-04-2021· The method of producing ferronickel at low temperature (1250–1400°C) has been applied since the 1950s at Nippon Yakin Kogyo, Oheyama Works, Japan. Limestone was used as an additive to adjust the slag composition for lowering the slag melting point. The ferronickel product was recovered by means of a magnetic separator from semi-molten slag and metal
Magnetic separation - Wikipedia
Magnetic separation is the process of separating components of mixtures by using a magnet to attract magnetic materials. The process that is used for magnetic separation separates non-magnetic materials from those that are magnetic.This tehnique is useful for the select few minerals which are ferromagnetic (iron-, nickel-, and cobalt-containing minerals) and

28-01-2016· 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.

In the end, you can recover the metals by means of crushing, grinding, flotation and magnetic separation. Besides, leaching one or two metals from the matte also can be used to separate the copper and nickel.

Nickel - Wikipedia
Nickel is a silvery-white metal with a slight golden tinge that takes a high polish. It is one of only four elements that are magnetic at or near room temperature, the others being iron, cobalt and gadolinium.Its Curie temperature is 355 °C (671 °F), meaning that bulk nickel is non-magnetic above this temperature. The unit cell of nickel is a face-centered cube with the lattice
