Hydrometallurgy (Nikel & Cobalt precipitation)

INDUSTRIES

Our highly reactive Magnesium Oxide in powder form is used in leaching processes of laterite ores as a neutralization reagent and in the precipitation of the hydroxides of metals such as nickel (Ni), cobalt (Co) or uranium (U) from their acid leachate solutions.

 

Our Kappamag–Hydro (96% MgO) & Deltamag-Hydro (94% MgO) have been particularly developed for Cobalt precipitation process. Their superior performance is achieved by combining our Multiple Hearth Furnace -the best calcination technology available to control reactivity -with the top-quality of our cryptocrystalline magnesite

​

‘’ very highly reactive grades with fully controlled and consistent characteristics ’’

 

‘’ the best calcination technology available to meet Co/Ni precipitation process requirements.’’

Product characteristics:

  • Highly reactive products (high specific surface area) of high purity (96% MgO) produced from cryptocrystalline magnesite

  • Fully controlled and consistent reactivity range (25-30 sec according to citric acid test), thanks to our advanced calcination technology (Multiple Herth Furnace).

  • Well and uniformly calcined grades

  • Quality consistency-no variations in reactivity, chemistry, sizing among batches/deliveries

  • Controlled particle size (d90<35μm)

Key benefits in use:

  • High cobalt hydroxide precipitation efficiency

  • Low magnesium oxide/cobalt consumption rate

  • Cost efficient solution compared to synthetic magnesium oxide reagents

  • Superior settling and filtration rate

  • Environmentally friendly (non-toxic) and safe reagent
