Utilization of two solid wastes of altered rock gold tailings and soda residue as main raw materials, and investigated the effects of soda residue, Al₂O₃ and MgO contents on bulk density, compressive strength and crystal phase of porous ceramics. The results showed that porous ceramics with the main crystalline phases of diopside can be prepared from high solid waste content (gold tailings + soda residue accounting for 95%) at 1170 °C. The addition of MgO made the final product generate augite phase, which improved the compressive strength of the porous ceramics. The best results of bulk density and compressive strength of the final product are 0.50 g/cm³ and 6.02 MPa respectively.

以两种经改变的岩金尾矿和苏打渣为主要原料的固体废物，研究了苏打渣，Al ₂ O ₃和MgO含量对多孔陶瓷体积密度，抗压强度和晶相的影响。结果表明，可以在1170°C下由高固体废物含量（金尾矿+苏打渣占95％）制备具有透辉石主要结晶相的多孔陶瓷。MgO的添加使最终产物产生了辉石相，从而改善了多孔陶瓷的抗压强度。最终产品的堆积密度和抗压强度的最佳结果分别为0.50 g / cm ³和6.02 MPa。
