Abstract

The nickel producing companies in the regions of Nicaro and Moa they have generated, during over 50 years, important volumes of solid residues, named Environmental Mining Metallurgic Passives (PAMMs), whose values can be increased in the Moa area, without concrete proposals for their utilization. The objective of the work is an update of the knowledge of the physical, chemical, mineralogical and thermal characteristics of different types of PAMMs, between the ones that the following highlight: lateritic rubble and solid residues of metallurgical processes the plant of the leaching processes high pressure acid (HPAL). The combination of different instrumental techniques: X-rays Fluorescence (XRF), X-rays diffraction (XRD) and thermal and differential thermogravimetric analysis (DTA, TGA) allowed to compare the characteristics and establish the physical - chemical and thermal regularities of these solid residues, that base the proposals of use, essentially for the Cuban and steel industry. In addition, the results of experimental test using lateritic rubble of Nicaro and Moa as a source of raw material for the production of a pre-reduced product in the production of nickel-based pig iron (NPI) and as an oxidizing material during the steelmaking processes.
