Processing of Nickel Laterite Ores on the Rise - Know More
Most laterite ore deposits are made up of both limonite iron rich and saprolite layers, with the thickness of each layer varying significantly across different deposits Limonite, which accounts for nearly double the amount of saprolite available globally, is more amenable to processing via hydometallurgical techniques, while saprolites are more amenable to processing via pyrometallurgy 185...
