ACTUALIZATION TO MINERALOGICAL KNOWLEDGE OF LATERITIC ORES AND SOLID WASTE OF CUBAN NICKELIFEROUS INDUSTRIES
Main Article Content
Abstract
This paper aims to provide information available to the Company Group Geominsal experts Geosciences concerning updating substantial compositional studies of Cuban deposits of lateritic weathering crusts and residual solids accumulated in the artificial reservoirs of technological processes of high pressure acid leaching (HPAL) and ammonium carbonate (CARON) in the three nickeliferous industries of the country, particularly through the use of four major advanced instrumental techniques that are used in routine analytical practice such as: Chemical Analysis of major elements, the X-ray diffraction (XRD), Thermal Analysis (TA) and Optical Mineralogy and Petrography, among others that were used and used during different stages of analytical development with lateritic ores, both in companies and in ancient geological GEOMINING current business Group for decades and so far in the main laboratories of the Business Group: CIPIMM, LACEMI and Elio Trincado and in some research centers country engaged in research with these important mineral resources that the country now has, including CEIINIQ and CIPIMM. The volume of the results concerning the elemental composition of these mineral phases, by using elemental analysis techniques and phase (DRX, A. Thermal, A. Chemical) combined with reconstruction calculations Mineralogical Petrography and descriptions, which were compiled in reports made at different stages in the NDRA MINBAS and research carried out in the CIPIMM, show typical mineralogical associations having different mineral species on lateritic deposits and Cubandepleted or in Current exploitation-as well as solid waste that accumulated during years in artificial reservoirs, with specific mineralogical characteristics (according to the natural type of ore (TNM) and industrial waste), therefore, these have validity and current methodological utility in Analytical laboratories of Mineralogy laboratory System Business Group, said because the guidelines to follow to make the appropriate Elemental Analytical Phases and Control (CAF) is needed during project implementation Geological Survey of Technological Research and / or Mining, running on future projects with geological Geominsal business Group companies and Nickel as well as partnerships or joint ventures that are interested in similar studies in our country.
