Hatch has extensive magnesium production experience, which includes feasibility studies, process consulting, EPCM, new technology development, and specialized equipment design.
Hatch’s experience extends to these magnesium-production process areas:
- Ore beneficiation: reclaiming, size reduction, drying, calcination and filtration
- Acid leaching: optimum leaching conditions, specialized leach-reactor design
- Brine neutralization and purification: impurity precipitation, solid/liquid separation, ion exchange, solvent extraction, pure brine production
- MgCl2 dehydration technologies: production of anhydrous and semi-dehydrated magnesium chloride and carnallite salts
- Hydrochloric acid production, regeneration and handling: specialized equipment and materials of construction selection
- Handling of corrosive and hazardous gases, particularly chlorine and hydrogen chloride gas: equipment selection, electrolytic off-gas handling and treatment
- Electrolytic cell technologies: including flow-lines and individually-tapped cells
- Molten metal and salt handling
- Casting: conventional and DC
- Magnesium metal recycling
- Environmental engineering for treatment of solid, liquid and gaseous effluents: leach residue, waste water, hydrochloric acid purification, chlorinated hydrocarbon (CHC’s) management, off-gas scrubbing
- Hydrogen gas production by reforming
- Thermal routes for magnesium production
