Theoretical Foundations and Technological Capabilities of Hydrocarbonyl Process while Recovering Copper from Technogenic Wastes

Fedoseev I. V., Barkan M. S., Kornev A. B., Danilov A. S.

Journal of Ecological Engineering

2018

Vol. 19, nr 5

33--37

Secondary processing of waste from metallurgical and other industries becomes an urgent issue in the face of increasing anthropogenic pressure and a shortage of sources of materials. The paper shows the results of chemical and technological studies of processes, executing in the Cu(II) – Cu(I) – Cl- – CO – H2О system. The processing technology of copper-bearing intermediate products multicomponent leaching solutions, permitting high purity copper production at the least economic cost, is proposed.

Use of Biological Adhesive for Effective Dust Suppression in Mining Operations

This article explores modern methods of reclamation of lands disturbed processes of mining, based on monitoring disturbed lands using unmanned aircraft and dusty surfaces coated biologically active adhesive, biological foam. In the article new highly efficint methods of remote monitoring of environment components are considered on based of unmanned aircrafts. For monitoring, it is suggested to draw complexes based of small unmanned aircraft vehicle, equipped with special equipment (a digital camera, a thermal imaging camera, dust meter). Land reclamation on the biological stage is encouraged by using new bioadhesives, developed on the basis of polysaccharides and various microorganisms. This composition helps reduce the consumption of fertilizers, pesticides and other components, pioneer in growing crops on dusty surfaces in the disturbed lands. As a result of such an event, dust discharge from the surface technogenic structures is reduced up to 10 times.
