A team of researchers from the Institute of Materials Science and Technology, of the University of Havana, established the basis for new procedures for the rational and sustainable evaluation of lateritic minerals in the province of Holguín.
The authors of the innovative initiative carried out with their samples a chemical analysis with an ionization source and an optical emission spectrophotometer that served to develop a methodology, according to information from the Academy of Sciences of Cuba (ACC).
In their tests, they used the laser excitation spectroscopy technique, which reduces environmental damage, and created a novel strategy called multienergy calibration applied to solid evidence, especially in the province of Holguín, which stands out for its mineral productions of nickel, cobalt, chromium and iron.
ACC specialists considered that the published results are original and interpreted, for the first time, as mechanisms of excitation and load transport, with an adequate characterization that allows developing chemical analysis of greater precision.
Seven specialized publications and dozens of papers at national and international events endorse this work and during the research two postgraduate theses of masters and doctorates were exposed with relevant results.
However, it also allowed a more accurate examination of other important metals in nickel samples and the daily work of the Cuban industry.
Miguel Díaz-Canel Bermúdez, President of the Councils of State and Ministers, confirmed last May the nickel development programs in areas of the mining-metallurgical municipality of Moa, about 180 kilometers northwest of the city of Holguín, capital of the province of the same name.
Díaz-Canel held meetings with workers and managers of the Comandante Pedro Sotto Alba nickel factory, the main processing center for that mineral on the Island, which is included among the products of greatest impact on Cuba's exportable programs.
At the factory, he learned about the current state of production plans that, according to the deputy general manager of the entity, engineer Carlos Iglesia, showed a 5 percent over-compliance from January to last May, a stimulating indicator for a well-known company in the national economy.
He also observed that Pedro Sotto Alba, with more than 1,900 workers, records favorable results in the investments of its main production areas along with the maintenance of equipment and other manufacturing facilities.
