Project Details


The Dominga project involves the construction of an open pit mine for the extraction and processing of iron ore with copper as the main subproduct. The project also includes a port facility for the shipment of iron ore, over a total area of 10,370ha. The project is divided into three main development areas: Dominga, Lineal and Totoralillo. The Dominga area includes the construction of two open pit mining areas, Rajo Norte and Rajo Sur, a processing plant, a waste dump and a tailings dam. The Lineal area includes two aqueducts which will be designed to supply the Dominga area with fresh desalinated and recycled water. Lineal also includes a slurry pipeline to transport iron ore concentrate to Totoralillo Norte's port facilities. The Totoralillo area includes an iron ore thickening system, a filtration plant, a desalination plant, storage and shipment facilities and a discharge system.
