Combination of leaching technologies with conventional ore processing techniques

The issue of efficiency promotion and optimization of subsoil use toward the complete use of accessed and extracted mineral resources is discussed. The aim of the research is the detailed elaboration of approaches to combining metal production technologies in underground mineral mining. The history of improvement of mining technologies as a framework for the refinement of ore mining and pretreatment processes is described, and the negative aftereffects of the reforms in the 1990s are generalized. As a tool of stabilization of mineral supply in the industry, it is proposed to combine the conventional technologies and the new metal leaching technology. A type design practice is proposed for the methods of improvement of metal leaching in disintegrators–activators. It is emphasized that leaching in disintegrators allows recovery of metals down to a sanitary standard, with elimination of storage of the conventional processing tailings. The problems connected with the strengthening of the mining industry, with the prioritized technological innovation in ore mining and processing, at the enhanced comprehensiveness of metal-bearing raw material use are generalized. A combination flowsheet is proposed for metal recovery at metallurgical plants, in-situ and heap leaching, and metal extraction from tailings in disintegrators is recommended. An idea of combining ore mining and processing methods within a mine field is put forward. An economic model is developed for evaluating efficiency of combining conventional and innovative technologies. It is shown that combination of ore mining and processing technologies is a promising resource for the improved sustainability of mineral supply in the industry. The novelty of the approach is governed by the addition of the technology with a cardinally new process of transition of metals to liquid phase in high-speed mills, with integration of mechanical and chemical energies within a single process, as well in in-situ and heap leaching within a mine field.

Keywords: combination, technology, ore, metals, mining, leaching, disintegrator, recovery, ecology.
