Purpose of the development: The development is designed for the extraction of rare, non-ferrous and heavy metals from waste coal preparation and ash from the burning of coal for the purpose of disposal of these wastes, and obtain valuable rare-metal raw materials.

Recommended application field: The coal industry, ferrous metallurgy and energy.

Advantages over analogues: It is a simplified method is implemented at normal temperature and pressure, without the use of strong acids and the formation of toxic intermediate products, making it environmentally safe. As a result of its application can gain valuable rare metal concentrate containing 3-5% of germanium and / or gallium and neutralized waste with lower (by the maximum allowable concentration for soil) containing heavy metal ions, as well as the ratio of the oxides of silicon, aluminum and calcium, which It corresponds to the composition of silicate building materials. Analogues in the world.

The development stage readiness: The working documentation is developed

Technical and economic effect: The method does not require expensive equipment, reagents scarce, is characterized by low energy and labor costs, is a highly cost-effective, quickly pays for itself. The amount of funds that are necessary for the implementation of industrial development depends on the volume of production and is scheduled 80,0-100,0 UAH. 1 t of wastes profitability - not less than 200%.

Description of the development:
()
The method is based on the ability of microorganisms chemolithotrophic a result of their livelihoods due to the oxidation of sulfur and its compounds to destroy the stability of the crystal structure of various natural and man-made substrates. Such an approach is environmentally sound, energy and resource efficient, highly cost-effective, advanced and most promising. Methodological and technological advice to test developed by biotechnology waste from burning coal and energy coal preparation tailings. Conducted model tests of the developed method for the extraction of rare metals (germanium, zirconium, gallium) of waste lead-zinc production, stockpiles of coal preparation and ash from coal combustion in power plants.
