Abstract
The invention provides a method of producing foam glass with copper tailings. The copper tailings, waste glass, coal black, sodium fluosilicate and sodium phosphate are added in a heat-resistant steel die after being put in a ball milling tank to be milled into 200 orders below. Then, the die is moved into a foaming furnace to obtain foam glass through the preheating, the foaming, the foam stabilizing and the annealing. The invention uses industrial waste copper tailings as raw materials to prepare the foam glass, added with a little additive. The invention is beneficial to the waste utilization and the environment protection. And the obtained foam glass has the advantages of structure with high strength, low water absorption rate, small density and low thermal conductivity. The invention can effectively lower the production cost of the foam glass, protect the environment and change wastes into valuables. The properties of the produced foam glass are that the density is smaller than 0.8g/cm<3>, the water absorption rate is smaller than 1.5vol percent, the average foam diameter is 1-3mm, and the flexural strength can reach to 2.0MPa.
