| Abstract: | Overlay technology in biological heap leaching process of low-grade copper ore in Zijin Mountain was studied. Economic benefit, budget analysis, and technical proposal of different overlay technology were compared. Different sealing materials and technical solutions were tested. Sealing technical solution after three layers of heap leaching was put forward. With absence of loess around, the modified raffinate neutralized slag was used as sealing material, and technical solution of geomembrane was used for sealing treatment. |

| Keywords: | low-grade copper sulphide ore biological heap leaching overlay technology closure heap modified neutralization slag |
