Premier Magnesia has been the trusted source of magnesium oxide for the chemical manufacturing industry. Owning and operating the only magnesia mine in the United States enables us to ensure the highest quality product and reliability of supply for companies using magnesia for the manufacture of products such as magnesium nitrate and magnesium sulfate.
Our chemical manufacturing clients understand that when it
comes to choosing a supplier, all magnesia sources are not created equally, and
that the way by which magnesium oxide is made from ore is just as important as
the quality of the raw material. Our products are high in purity and reactivity
as a result of calcining under exacting conditions in a computerized Herreshoff
multiple-hearth furnace. Multiple burners within each hearth enables
Premier to attain the precise calcining conditions while maintaining a
consistent temperature. This unique process creates a much higher reactivity
product, as compared to magnesium oxide produced through the more common method
of using a single-burner rotary kiln, which often yields inconsistent product
as result of fluctuating temperatures, and thus unreliable reactivity.
Dependability of performance and reliability of supply has
kept clients in chemical manufacturing coming back to our mine for product for
over 50 years.
