VELIZ-JARDINES, Ada Iris  e  MIRANDA-LOPEZ, Jorge. Researches of development on the Caron process of laterities technologies during the prosecution of the lateritic overburden or the low law of nickel ores classified as: industrials ores or not industrials. RTQ [online]. 2022, vol.42, n.2, pp. 360-383.  Epub 30-Ago-2022. ISSN 2224-6185.

The work exposes to the authors consideration a summary of technician-historical aspects related with the Caron process, new approaches and technical procedures, as well as those accumulated given by the experiences acquired by geologist-miners, technologists in investigations in the context of the Cuban industry of the nickel. The XXI century it outlines new and transcendent challenges for the industry, one of them, is related with the variability of the ores processed today in day for this technologies that generate behaviours dissimilar as for metallurgical efficiency and operative to commercial scale. However, the strategies of sustainable development are being defined without an enough diagnosis of the multi-causal problems, originated to the lack of new mineralogical knowledge and of opportune identification in the own dynamics of the industry, based on the priorities of to maintain or to overcome the productive increments from these chords to the standards and international demands. The objective of the work is to show reinterpreted results in a different way, and to complete the square of chemical-mineralogical identification of the fewer of low nickel law, with high iron content and of the lateritic overburden, in search of its previous operative diagnosis, through new procedures of contributed rehearsals that they identify, if they are of industrial prosecution or not, this knowledge are in disposition of the scientific and technological community, based on "New interpretation focus "physical-chemistry" during its thermal treatment in an atmosphere “oxidizer or reduction", as well as of other techniques of magnetic identification and of thermal treatment.
