Mineral Development Center - The technology behind mining
For nearly 50 years, our laboratories located in Santa Luzia (Minas Gerais) have been the birthplace of most of Vale's mineral projects.
Whether on a mountain top, miles below the surface, or even in the middle of the Andes. No matter where Vale operates, research will begin at our Mineral Development Center (MDC). Vale investigates methods to produce and process various types of ore there.
For nearly 50 years, the laboratories located in Santa Luzia (state of Minas Gerais) have been the birthplace of most of Vale's mineral projects. Engineers, chemists, geologists and other experts conduct various studies and tests to ensure project viability.
This initial research generates fundamental information for implementation and operation:
- What is the quality and concentration of minerals?
- What is the mine’s forecast lifespan?
- How can we develop environmentally sustainable technologies?
- What type of technology should be used for extraction and transportation?
Get to know the minerals Vale has researched in more than 70 years:
The MDC is considered the most sophisticated and complete laboratory complex geared to research and development in the mineral area in Latin America, and one of the most modern mineral technology development centers in the world. It was the first of its kind to be granted the ISO 14001 environmental certification, and Vale's first research center in Brazil to be ISO 17025 certified.
MDC is researching innovative bioleaching techniques, using bacteria to extract metals such as nickel and copper contained in minerals not currently processed. Microorganisms already existing in the soil are bred in incubators in our laboratories. The idea is to use them as “accelerators” of chemical reactions, helping to reduce the consumption of reagents and water.
One of the research projects in progress at the MDC is on rare earth minerals. Despite their abundance in nature compared with other minerals, they are more difficult to extract due, in part, to their chemical compositions. These metals are high-tech industry raw materials, commonly used in the production of green technologies such as catalysts, parts for wind turbines, and even hybrid cars.
When the MDC was created, the hematite reserves in the Cauê Mine, Vale's first mine, were increasingly deep, threatening the operation's feasibility. Thus, it was necessary to create a technology that would allow high-grade ore to be extracted and used at low costs and also process itabirite with low iron content. The MDC led the way, and Vale bet on the pioneering use of the magnetic separators.

Mineral research in the Andes
Always in pursuit of innovation, Vale has used photovoltaic panels to substitute for diesel fuel consumption by generators at one of the mineral research projects around the world the MDC partners with.
Located in the Andes, in the Atacama region, in Chile, at an altitude of more than 4,000 meters, solar energy is used mainly to heat the camp's lodging facilities, where about 70 people work. Discover curiosities in the photo gallery.
