Once crushed, the ore will be transferred to the flotation process, whereby "first lead and then zinc, they are separated from the rest of the ground material, concentrating from an initial grade of around 4% to a grade of about 61% in the case of Zn concentrate and 70% in the case of Pb." The process ends with the processing of the waste to dry deposit it in a rubbish dump on the surface and wet back to the mine.
The product is transferred by bulk truck to a foundry, such as the one found in Castrillón (Asturias), to obtain high purity zinc, lead and silver after refining.
Currently, the Europa Metals project is in a time of Exceptional Extension for three years to maintain the research and has already been presented to the municipalities of Sobrado, Carucedo, Toral de los Vados, Carracedelo and Borrenes. Until November 15, 2023, Europa Metals will continue to design its mining project in Toral to submit the application for the Grant of Operation in the shortest possible time.
The consultancy 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 announced to give birth to a Pre-Viability Study (PFS). Within that study, the company Probes and Industrial Drillings of Bierzo SA (SPI) is carrying out a new drilling campaign since the beginning of this year.
With the data from that survey, the data will be processed to develop software "that corrects the deviation of the boreholes carried out by drilling with core recovery," the company explains. At the same time, the company seeks support for its project as an R&D focus.
In this sense, he assures that professors of 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 the Mining, 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 so-called Toral Project.
