The history of the Rima Group dates back from more than 50 years ago and started in 1952 when Mr. Osvaldo Vicintin founded Metalur Ltda in the city of Sao Paulo, Brazil. In 1974, Mr. Ricardo Vicintin, his elder son, moved to the state of Minas Gerais and founded Eletrometalur S/A, which became the Rima Group in 1982. Today, Rima is a company with global reach that respects the environment and the communities where it does business.

1974 - Eletrometalur, the first industrial unit, was created in the city of Varzea da Palma in the northern region of Minas Gerais State.

1978 - Furnace # 2 starts the production of 75% Ferro Silicon

1979 - Furnace # 3 starts the production of 75% Ferro Silicon and it is then converted to the production of Calcium Silicon Alloys.

- Brasmag, the only magnesium producer in the Southern Hemisphere, is created in the city of Bocaiuva, in the northern region of Minas Gerais State.

1987 - The Rima Group is formed.


1980 - Furnaces # 4, 5, and 6 start the production of Silicon Metal in 1980, 1984 and 1989, respectively.

2001 -The Rima Group takes control over the “Capitao Eneas” plant and becomes the largest silicon metal producer in Brazil and the fourth in the world.

- The Diecasting Division is formed to supply magnesium diecasting parts to the automotive industry.

2006 - In this year, the Rima Group reinforces its strategy of vertical integration by investing heavily on its Mining Division (search for new reserves of quartz and dolomite) and the Forestry Division (development of eucalyptus clone saplings and charcoal production).

2007 - In 2007, the Rima Group establishes itself in the automotive industry by creating an assembly unit for automobile engines. This step follows the company culture of adding value and technology to its products.

- In March of 2008, the Rima Group became the first company in the world in the mining and metallurgy segments to have a project approved for the sale of carbon credits. This project was approved by the United Nations Organization and removes approx. 35.000 tons per year of CO2 from the atmosphere, i.e., the equivalent of planting 350 thousands trees per year.

- Continuation of investments in new charcoal production technologies and utilization of biomass energy.

- The Technology of Solar Grade Silicon is developed, a high value-added product..

2008 - The Rima Group implements in the city of Bocaiuva a new unit to melt and diecast aluminum, becoming one of few diecasters producers in the world with the flexibility of supplying both magnesium and aluminum diecasting parts to the automotive industry.
