How to Recover Chromium Nickel Cobalt Laterite

Jan 06, 2021  Gravity separation and flotation were less effective than magnetic separation in cleaning magnetic products. Goethite is the principal constituent of laterite, making up about one-half of its weight. In treating the laterite by reduction roasting and ammoniacal leaching, the goethite is reduced to maghemite or a hydrated magnetite.
