| Summary: | The present invention is related to treatment of glass waste products, and more specifically to a method and systems for extracting heavy metals from glass waste.
A method and systems are provided for extracting heavy metal from glass waste. Glass is initially crushed to a diameter size of about 2 millimeters. The glass is then added to a tank having a solution of water and acid, where the acid removes metal from the surface of the glass particles. The solution is then separated from the glass particles. In some embodiments, the glass particles are also rinsed with water and the rinsed water is treated to remove any residual contaminates. In more embodiments, the solution can be reused for a number of iterations that treat glass waste in order to extract heavy metal from the glass waste. |
