The laterite ore or concentrate is subjected to a leaching step with a lixiviant comprising hydrochloric acid to leach nickel from the laterite ore, followed by a liquidsolids separation step. the liquid obtained is subject to solvent extraction with a dialkyl ketone, to obtain a solution rich in iron and a raffinate.
Using the fact that the iron is magnetic, the magnet can be used to separate the iron fillings from the mixture by moving teh magnet around in the container. keeping the magnet in a plastic bag makes it easy to separate the filings from the magnet when you pull it out.
The separation and identification of gangue are done based on the differences in colour or lump shape. hydraulic washing. it also refers as gravity separation or levigation. in the hydraulic wash, the ore is separated from the gangue by the principle of gravitational force. the ore is first crushed into fine particles or powdered form.
