“…In Russia the most common agent used in flotation processing of gold-bearing raw material is butyl xanthate. There is a positive experience of re-flotation of the tailings containing noble metals in our country and abroad [3,[15][16][17][18].…”

The research results on floatability of old gold-bearing tailings are presented. The complex material composition and process features of processing waste are governed by difference in treatment of various ore types (sulfide, oxidized and mixed) at processing plant, as well as with supergene processes in the tailings pond. Feasibility of re-flotation of tailings is discussed. It is found that short-term mechanical activation of tailings in a mill with the subsequent flotation (at the adjusted reagent mode as against the current technology) results in gold recovery of 29.0 to 45.4% in flotation concentrate at the residue content of metal in rejects at the level of 0.2-0.3 g/t.

“…The problem of separating minerals with similar technological properties is solved by increasing the selectivity of separation in concentration processes -using directional reagents, selectively changing the technological properties of minerals using various energy influences [4,5]; in [6] the methods of concentration and extraction of ultrafine dispersed gold using methods of laser exposure are proposed.…”

With the samples of the gold-antimony ore processing products of the Sentachan deposit, flotation experiments were carried out on a laboratory centrifugal flotation machine with peripheral concentrate discharge (CFM) and on a laboratory mechanical flotation machine (FM). The selectivity of falling of mineral particles from the flotation mineralized foam flowing along the inclined plane after flotation under different modes (with and without the use of a collector) was investigated; it was shown that the use of a collector can regulate the intensity and selectivity of the falling of material from the foam layer. It was found that the combination of the effect of the centrifugal force of fluid rotation and the hydrophobic properties of minerals makes it possible to enhance the selectivity of the separation of minerals; during flotation in a centrifugal flotation machine, it is possible to carry out cleaning operations in order to improve the quality of the concentrate.

The paper presents the results of theoretical and experimental studies into the development of scientific and methodological bases of environmentally-driven resource-saving technologies for mining waste processing. It is shown that the logic of reconstructing the natural cycles of natural resource equilibrium requires the inclusion of large-tonnage wastes in the status of their technogenic mineral resources in highly efficient, resource-efficient processing, which determines the need to develop innovative technologies for processing wastes very diverse in composition and properties within the framework of the principle of a systematic approach. The methodological basis of theoretical development of new environmentally oriented technologies for waste processing defines the method of scientific knowledge as an ascent from the abstract to the concrete and the construction of technologies according to the developed general algorithm. In accordance with the general methodological approach being developed, technologies have been developed for processing certain types of mining waste - off-balance copper ores from the dump, stale tailings of gold ore from the tailings; iron-zinc-containing blast furnace sludges of metallurgical production by combining several enrichment or concentration and hydrometallurgical methods. The developed resource-saving, environmentally friendly technologies provide the opportunity to involve previously unused resources of technogenic origin into efficient operation with obtaining conditioned metal-containing products and reduce environmental stress in regions with a developed mining and metallurgical industry.
