Mineral extraction is preceded by the deployment of infrastructure to mitigate the impacts that will be caused by the mining, as discussed extensively in the environmental studies approved by federal and state agencies. Upon the exhaustion of an ore body and/or part thereof, topographic reconfiguration will be commenced, followed by vegetation consistent with the surrounding area. Extraction and pit rehabilitation are carried out sequentially and successively. The visual impact lasts for a relatively short time, and changes to the contour become imperceptible over time.

To ensure a broader biodiversity of the vegetable coverage in the rehabilitated areas, the company has set up a plant nursery. It identifies native forest species, collects seeds and produces seedling of the vegetation that occurs naturally in the regions where it operates.

This initiative provided the knowledge of the methods for breaking seed dormancy and for producing seedlings of approximately 205 native and exotic tree species, including fruit trees to attract wildlife and restore the process of natural succession and development of revegetation. About 50,000 seedlings are produced every year, which are used in the rehabilitation projects of mined areas (25%) and also donated to the community (75%) and to partnering public or private environmental reclamation projects

The Company has sponsored, for more than one decade, an Environmental Education Program to about 2,000 primary school children of the local government schools.

The donation of native and exotic species to small farmers has reached 35,000 seedlings/year. For many consecutive years, the Company has held partnerships with the Municipalities of Poços de Caldas, Caldas, Andradas, Senador Amaral, Bom Repouso, Manhuaçu and Simonésia to foster environmental conservation and the intensification of riparian forests.

The Creation of a Private Natural Heritage Reserve [RPPN]: A farm [“Fazenda das Pedras Leste”] located on the Poços de Caldas plateau, with an area of 260 hectares and the project management of Saturnino de Brito dam basin, one of the city's water supply sources, are major highlights of the company's environmental activities.

Environmental Management Programs

In recent years, a number of environmental management and impact control projects and programs have been implemented in the industrial units, some of which are highlighted below:

  • 01Control of atmospheric emissions by replacing fuel oil by natural gas, in addition to modernization of equipment, gas filtration systems and retention of particulate matter.
  • 02Control of wastewater with the implementation of a new sewage treatment plant and recirculation of the water used in the industrial process.
  • 03Selective collection, recycling and/or reuse and proper disposal of solid waste.
  • 04Recovery and reuse of ore fines in the production process.
