We are the only primary Magnesium producer in the Southern Hemisphere and the only one in the world producing automotive parts from ore utilizing a highly vertically integrated process. Being one of the lightest structural metals, magnesium brings several advantages to our final products, reducing their weight in up to 30% when compared to aluminum. This allows for the production of lighter automobiles, which in turn reduce emissions.

Dolomite, which is the primary raw material used in the production of magnesium and its alloys comes from Rima’s own reserves and is calcined in a rotary kiln. The calcined dolomite is then reduced in a silicon-thermic process under vacuum yielding magnesium crystals, which are then further processed to reach final specifications.

Rima Industrial produces a full line of Magnesium products including pure Magnesium ingots, Magnesium Alloys, Magnesium powder, Magnesium-based mixes and Magnesium Diecasting parts.

• Mettalic Magnesium

Magnesium is an important alloying element in the aluminum industry, principally in the production of automotive parts, extruded products and beverage cans. It is also used as a reducing agent in the production of special metals such as zirconium and titanium andin the Pyrothenics and in cathodic protection indsutries, among others.


Magnesium is also used in the ductile iron production to promote the nodularization of graphite and also as an alloying element in the production of magnesium-based ferroalloys.

• Magnesium Alloys

Magnesium Alloys are used in a variety of foundries, mainly in diecasting production for automotive industry, tools, electronic equipment such as computers and mobile phones, when light weight is important.

• Magnesium for the desulfurization of pig iron.

In a powder form and mixed with other materials, Magnesium is commonly used as a desulfurizer in many metallurgical applications and offers the best performance and cost benefit in the following cases:

1 - Iron requiring low levels of Sulfur, below 0.010%
2 - Limited time for desulfurization in steel making
3 - Heats with low temperatures.
4 - Heats with high initial levels of Sulfur

The most common desulfurizing mixture is pulverized lime and Magnesium powder (below 1 mm in size). The Magnesium content in the mixture varies from 5% to 20% depending on the type of injection equipment and the available time for desulfurization

• Desulfurization Equipment

Rima manufactures and supplies sophisticated injection and co-injection equipment for desulfurization of pig iron. The company maintains a specialized group of trained technicians and engineers that provide the best available technical support and assistance.
