Abstract
Coal tailing and piles of coal are dangerous for the environment but, on the other hand, they could be considered as significant indust-rial raw materials to obtain rare metals. There are more than 1,100 slagheaps in our country which contain more than 160 million tons of dangerous but significant raw materials [1, 2]. Biotechnological methods are the most promising to extract valuable components from coal tailing and to decrease its toxicity. Using these methods it is possible to process unprofitable depleted raw materials with the minimal resource costs and environment damage [3–5]. In this case it is necessary to carry out a complex chemico-biological evaluation of the initial substrate i.e. to study quantitative and qualitative composition, leaching activity of aboriginal bacterial community and possibility of selective isolation of active cultures of acidophilic chemolithotrophic bacteria.The aim of this work was to study the composition of the aboriginal bacterial community living in coal tailing and to evaluate what contribution in leaching activity is made by different groups of microorganisms which are present there. This investigation is continuation of the work started earlier concerning the evaluation of quantitative and qualitative composition of microbiocenoses from energetic waste [9].

Tailing and to evaluate lixiviation activity of different groups of microorganisms belonging to this community
The optimal results were achieved for collective leaching of rare and heavy metals into the solution under thermophilic conditions, which are favorable for the growth and activity of Sulfobacillus an d under mesophilic conditions with the usage of ferrous iron as an energy substrate
Comparing our results with the available literature data we made a conclusion that the qualitative composition of acidophilic chemolithotrophic bacteria living in technogenic waste did not differ from the microbiocenose structure of natural sulfide ores
