Mineral Processing and Environmental Protection Laboratory

Lab activity

Mineral Processing and Environmental Protection Laboratory is equipped with laboratory scale mineral processing equipment, which also represents the core activity of the laboratory. Laboratory scope of activities includes the areas of environmental protection, introducing wastewater treatment, the measurement of airborne emissions from stationary sources and soil cleaning as well as waste recycling (i.e. waste mining), especially WEEE recycling.
