The technology of processing out of ballance ores, dumps, lying and current tails of concentrated factories is offered.

• gravitational enrichment (combination the processes of jigging, screw and centrifugal separation, concentration on tables, enrichment of olags);
• flotation (collective, collective - selective, selective with use of the effective collectors and established combination little-toxic of reagents-modifiers);

• low power consumption;
• little-waste (utilized up to 90 % of wastes);
• ecological safety (little-toxic reagents);
• high technological-economic parameters (extraction from waste of gold and silver 70-90 %, non-ferrous metals 60-80 %).

The technology was tested in integrated - laboratory conditions on objects Gaiskiy, Zirianovskiy, Leninogorskiy and Dalnegorskiy polymetal plants. It is accepted to development on Gaisky factory.

Forms of cooperation:

· realization of tests of extraction technology in commodity concentrates of noble and non-ferrous metals from technical formations(educations);

· drawing up of the recommendations under the technological rules.
