Consorcio Minero Benito Juarez Peña Colorada, S.A. de C.V. (Peña Colorada) holds mineral rights over 99,188 acres in the province of Minatitlán in the northwestern part of the State of Colima, Mexico. ArcelorMittal owns 50% of Peña Colorada Ltd., and Ternium S.A. owns the other 50% of the company.
Deposit Type
- Magmatic
- Hydrothermal
- Banded iron formation
Summary:
Peña Colorada is a complex polyphase iron ore deposit. The iron mineralization at Peña Colorada consists of banded to massive concentrations of magnetite within breccia zones and results from several magmatic, metamorphic and hydrothermal mineralization stages with associated skarns, dykes and late faults sectioning the entire deposit.
Processing Technologies
- Magnetic separation
- Rotary kiln & Electric furnace
Summary:
Peña Colorada operates an open pit mine as well as a concentrating facility and a two-line pelletizing facility. The beneficiation plant is located at the mine, whereas the pelletizing plant is located in Manzanillo. Major processing facilities include a primary crusher, a dry cobbing plant, one autogenous mill, horizontal and vertical ball mills and several stages of magnetic separation. The concentrate is sent as a pulp through a pipeline from the mineral processing plant.
The Peña Colorada pelletizing facility produced 2.9 million tonnes of pellets in 2016. Both magnetite concentrate and iron ore pellets are shipped from Manzanillo to ArcelorMittal Mexico, as well as to Ternium’s steel plants, by ship and by rail.
