Founded in 1969, Mineração Taboca was pioneer in tin mining and metallurgy in Brazil. In the 80’s, with the discovery of the Pitinga mine (AM), situated 300 km away from Manaus, it was consolidated as one of the most important companies in the country in the mineral segment.
In the middle of the Amazon Region, the company implemented an urban-industrial, dwelling, education, health, energy and telecommunications complex making Pitinga one of the most important industrial projects in the country.
Cassiterite and columbite ore mining and processing are performed in Pitinga and, after years of researches and investments, in 2006, the company started the process of alluvium substitution for the extraction of primary rock, what is called “Rocha-Sã” [Healthy Rock] project. The cassiterite and columbite are concentrated in several equipments, mainly jiggers, spirals, tables, electrostatic and magnetic separators.
Mineração Taboca performs the cassiterite concentrate casting in its branch situated in the countryside of the State of São Paulo, to where the whole production of cassiterite concentrate obtained at the Pitinga Complex is taken. The Tin extraction is performed through electric reduction furnaces.
The columbite concentrate is processed in Pitinga (AM), where it is used as an input in the production of FeNbTa metallic alloy.
Mineração Taboca works in harmony with the Environment, concerned about the recovery of degraded areas. In Pitinga, 2,900 ha have been recovered since 1998 with the planting of about 740 thousand seedlings of native forest species and ornamental plants.
In 1961, Paranapanema, a family company at that time, started its history as a heavy civil construction company.
In 1969, Paranapanema discovers the existence of cassiterite – tin ore – in the Amazon Region and is granted mining rights in several areas in the tin province of Rondonia, founding Mineração Taboca S.A.
In 1973, Paranapanema incorporated Mamoré Mineração e Metalurgia company, verticalizing the production and starting to produce refined tin.
In 1974, after years of investments, Paranapanema consolidated technology to concentrate cassiterite derived from alluvial deposits.
In 1979, Mineração Taboca discovered, through geological researches, the first promising signs of the existence of cassiterite in tributaries of the Pitinga River, in the State of Amazonas.
In 1982, Mineração Taboca started the implementation and mining in the mine 300 km away from Manaus (AM), which was then called Pitinga, generating resources that turned it into a self-sustained project.
In 1987, investments in research and development allowed Mineração Taboca to make progresses in technologies for processing Niobium and Tantalum-rich ores, also present in the Pitinga mine.
In 1996, a pool of pension funds acquired the stock control of Mineração Taboca, Mamoré Mineração e Metalugia, adopting the name Paranapanema to call the new conglomerate of companies directed to the production of non-ferrous metals.
In 2002, Mineração Taboca was certified with ISO 9001:2000.
In 2005, Mineração Taboca SA leased the Mamoré Mineração e Metalurgia’s facilities, in the countryside of São Paulo, consolidating its tin mining and metallurgy activities under a single company.
In 2006, after years of research and investments, Mineração Taboca started the process of alluvium substitution for the extraction of primary rock, what was called “Rocha-Sã” [“Healthy Rock”] project.
In 2008, the traditional Peruvian mining group Minsur, acquires the stock control of Mineração Taboca and Mamoré Mineração e Metalurgia.
Investments made to increase the mine production through the extraction of ores directly from the raw rock in substitution to the mechanized alluvium mining.
The utilization of primary rock, besides providing new minerals, optimizes and makes the cassiterite extraction permanent.
The purpose of this internationally acknowledged and innovative project is to reach the production of 10,500 tons of refined tin per year by 2008 and, in a later expansion stage, possibly reach up to 14,000 tons per year.
