Once the mineral has been crushed, it will go through the flotation process, whereby «first the lead and then the zinc are separated from the rest of the ground material, concentrating from an initial grade of around 4% to a grade of around 61 % in the case of Zn concentrate and 70% in the case of Pb ». The process ends with the processing of the residue to deposit it dry in a dump on the surface and wet back to the mine.
The product is transported by truck in bulk to a smelter, such as the one in Castrillón (Asturias) , to obtain high-purity zinc, lead and silver after refining.
Currently, the Europa Metals projectIt is in a time of Exceptional Extension for three years to maintain the investigation and it has already been presented to the City Councils of Sobrado, Carucedo, Toral de los Vados, Carracedelo and Borrenes. Until November 15, 2023, Europa Metals will continue designing its mining project in Toral in order to present the application for an Exploitation Concession in the shortest possible time.
The consulting firm Bara Consulting has been developing its conceptual study of the project especially in the areas of metallurgy, resource estimation and geotechnics, something that will be released to give birth to a Pre-Feasibility Study (PFS). Within this study, the company Sondeos y Perforaciones Industriales del Bierzo SA (SPI)has been conducting a new drilling campaign since the beginning of this year.
With the data from this survey, the data will be processed to develop software "that corrects the deviation of the surveys carried out by drilling with core recovery," they explain from the company. At the same time, the company seeks support for its project as a focus of R&D.
In this sense, he assures that professors from the Faculties of Biology or Geology of the University of Salamanca, of Biodiversity at the University of León , as well as of the Miguel Hernández University of Elche , and researchers from departments such as Biodiversity and Environmental Management, through departments such as Ethnobotany, Taxonomic and Plant Conservation at the University of León or Mineralogy, Petrology of the Complutense of Madrid, contribute from the academic field their technical solvency to contribute to the technical, social and environmental standards of the called Project Toral.
