Разработка эффективной технологии получения металлополимерной композиции из отходов сорбционного выщелачивания золота

Аннотация

Subjects of research: metal polymer compositions formed at sorption leaching of gold from gold ores. Waste of unit of delivery of pitch on regeneration (“shepa” and sand). Purpose of work: development of effective technology of reception metal polymer compositions from waste of sorption leaching gold by their additional flotation in gold extraction manufactures. Methods of w'ork: in work physic mechanical, chemical and physical and chemical methods of researches flotation processes and waste of unit of delivery of pitch on regeneration arc used. For calculation of technological losses metal polymer compositions on all repartitions of sorption leaching the computer program is used. The results obtained and their novelty: as a result of the lead researches laws of formation ferro-and ferricyanides arc established at sorption leaching of gold. Negative influence formed ferro-and ferricyanides on capacity and flotation properties anion exchange pitches is established, diagrams Purbc of sorption leaching of gold is constructed. For extraction of functional classes metal polymer compositions from “shepa” and from sand allocated in unit of delivery of pitch on regeneration for the first time have been used a method of flotation. The effective technology of reception metal polymer compositions from waste of sorption leaching of gold is developed. Practical value: the developed technology of reception metal polymer compositions will allow to reduce losses anion exchange pitches with production wastes, to lower the cost price of let out production and to raise efficiency of process sorption leaching of gold ores. Degree of embed and economic effectivity: at approbation of technology in the integrated laboratory conditions on the basis of laboratory “Enrichment of minerals” The Tashkent state technical university. Extraction metal polymer compositions from “shepa” has made compositions 94,3% and from sand 96,22%. Losses of pitch thus decrease with 6,5 up to 1,29%. Expected economic benefit at introduction of technology of reception metal polymer compositions on a gold extract factory productivity 600 ton ores in day will more than 80,0 million sum in a year. Field of application: mining-metallurgical industry.
