Hydrochloric Acid Leaching

Cost efficient and sustainable

HCl is completely recovered using our

Acid Recovery Process (ARP): this gives

independence from chemical suppliers

and greatly enhances the environmental

performance of the overall process

Added value through valuable by-products

Integration of an Acid Regeneration Plant (ARP) produces metal oxide as a high quality

by-product. Depending on the desired properties of the oxide we can offer an ARP based

on either the Spray Roaster Process (SR) or the Fluidized Bed Process (FB)

Calcination, Sintering and Roasting of Industrial Minerals



SolventExtraction

Leaching

Pyro-hydrolysis

Calcination is mainly a thermal decomposition of carbonates and hydroxides. The mainchemical reactions may be expressed as:

CMI NESA® Multiple Hearth Furnaces (MHF) are particularly suited for the production of

calcined industrial minerals having specific reactivity, requiring good control of retention

time, temperature and atmosphere.

Sintering is the bonding of adjacent surfaces of particles in a mass of powder or a compactby heating. CMI offers sintering based on shaft kilns particulary suited for the sintering of

dolomite, magnesia briquettes, alumina and zirconia. Typical capacity of plant is in the order

of 25,000 to 60,000 tons/year.

Different types of Roasting can be achieved in CMI NESA® MHF:

Oxidizing Roasting of Molybdenum Sulfides MoS2 + O2 -> MoO3 + 2 SO2 Selective roasting for the treatment of complex sulfide concentrates in order to

volatilize elements such as As, Sb, Bi and Hg.

whereas Me refers to Mg, Ca, Mn, Pb, Zn.
