Unlock Higher Recovery in Hydrometallurgy with EMAG45!
When it comes to precision and performance in hydrometallurgical precipitation, EMAG45 from Queensland Magnesia (QMAG) stands in a league of its own. Produced from one of the world’s largest cryptocrystalline magnesite deposit in Queensland, Australia, EMAG45 is QMAG’s highest reactive caustic calcined magnesia, engineered specifically for demanding metals recovery applications.
In fact, EMAG45 made history as the first magnesia product ever used to successfully precipitate nickel hydroxide in Australia, and then cobalt from acid leached copper/cobalt ores in Africa. The introduction of this process revolutionized hydromet flowsheets and paving the way for efficient recovery of nickel, cobalt, rare earths and uranium zinc.
Why EMAG45 leads the industry:
- Ultra high reactivity for fast, selective metal precipitation
- High MgO content and strong neutralizing strength
- Proven effectiveness for over 25 years in high pressure acid leach (HPAL) circuits
- A trusted, reliable and highly consistent reagent in the production of nickel and cobalt intermediates essential for batteries and clean energy technologies
- Achieves the lowest MgO consumption rate in both Ni and Co precipitation, maximizing operational savings
As global demand for battery metals accelerates, EMAG45 continues to support cleaner, smarter extraction processes - helping hydrometallurgical plants improve efficiency while contributing to the world’s transition toward net zero technologies.
EMAG45 is available in 25kg bags, 1 metric ton big bags and Bulk in Container (BIC).
