CMI Group
With decades of experience in pyrohydrolysis, calcination, sintering, and roasting, CMI Industry offers a full range of innovative solutions from initial feasibility studies and pilot plant trials, to full scale plants.
Related Up-and Downstream Processes
CMI‘s technologies allow for the most effective and cost efficient extraction of a wide range of metals by chemical and physical methods. As such CMI can supply pyrohydrolysis acid regeneration plants based either on fluidized bed (FB) or on spray roaster (SR) technology.
- Solid / Liquid Separation: Filtration – Thickening - Flotation
- Chemical / Physical Separation: Solvent Extraction (SX) - Ion-Exchange (IEX) – Precipitation - Ad-/Absorption - Membrane Process - Calcination – Sintering - Roasting
- Metal Recovery : Chemical Reduction – Electrolysis - Cementation
Typical Applications
CMI’s unique product range in the field of metal extraction solutions suits the production of a wide variety of valuable intermediate and finished compounds (ore concentrates, hydroxides, mixed oxides).
- Magnesia (DBM, CCM +98 wt%, Sinter +99wt%) from Magnesite, Serpentine, Dolomite, Brucite, Bischofite, flue dust, end brines from Potash production
- Synthetic Rutile (+95.5 wt% TiO2) and Titanium dioxide pigment grade (+99 wt% TiO2) from Ilmenite
- Nickel oxide and Cobalt oxide from Laterites
- Alumina from clays
- Rare Earth Oxides (REO) from Monazite, Bastnasite, Loparite, Xenotime
Additionally, CMI and its partner Ti-Cons combined their competences and offer an Integrated Process for the production of titania pigment from ilmenite or upgraded slag.The process combines CMI’s Synthetic Rutile Process and the Chloride Process (CP) offered by Ti-Cons.
