【 摘 要 】

The paper presents the results of studying the absorption of heavy metal ions from a multicomponent solution by coal mining waste. Acidic drainage solution was obtained by water leaching of technogenic sand of tungsten-molybdenum factory. It was found that manganese, zinc, copper and iron have high concentrations in the solution. Copper, iron and lead have a high affinity for the surface of coal. The usage of oxidized brown coal as an adsorbent can significantly reduce the concentration of heavy metals in multicomponent solutions despite their complex composition.
