Scientists from Perm Polytechnic University have patented a unique technology for purifying mine water. The simple, cost-effective method not only completely removes hazardous contaminants, including persistent lithium, but also converts them into useful products.
Coal mine closures are a global trend. However, after their elimination, an acute environmental problem arises: the mines are filled with water, which comes to the surface. These so-called mine waters contain a high concentration of heavy metals and sulfuric acid, poisoning the soil and water bodies. Restoring damaged nature may take decades.
Lithium removal is particularly challenging. This element remains dangerous even after standard cleaning, making the water unsuitable for further use.
Scientists at Perm Polytechnic University have found a solution to this problem. They have developed innovative technology that provides deep water purification. The method is simple and does not require expensive reagents or complex equipment. This allows it to be used both in stationary treatment plants and directly in places where contaminated water comes to the surface.
The main advantage of the technology is an integrated approach. It not only purifies water from a wide range of hazardous components, but also transforms them into useful commercial products. As a result, you can obtain a metal-containing concentrate, lithium carbonate, or even liquid fertilizer. New development Perm Polytechnic is a promising step in solving environmental problems in mining regions. The technology is already protected by a patent and is ready for industrial implementation. Its economic attractiveness and adaptability open up opportunities to create new sources of income, turning an environmental threat into a useful resource.
