Title:
APPARATUS AND METHOD FOR TREATING MINE WASTE
Document Type and Number:
WIPO Patent Application WO/2010/044595
Kind Code:
A2
Abstract:
The present invention relates to an apparatus for reusing metal mine waste and to a method for treating the latter, which effectively separate and recover metals which are precious minerals from metal mine waste, and reuse the residuals thereof as materials for cement, to thereby minimize the causes of environmental contamination and to maximize the reutilization of resources which might otherwise be treated as waste to achieve economical advantages. The apparatus of the present invention comprises a vibrating sorter for sorting metal mine waste, a kiln drier connected to the sorter to dry the metal mine waste discharged from the sorter at a temperature of 400°C or higher, a heat accumulator for supplying heat energy to the drier, a grinder for grinding the dried metal mine waste discharged from the drier, a specific gravity sorter which sorts the ground metal mine waste through a floating method by the specific gravity of metal minerals and non-metal minerals such as silica, lime, and the like; and a high frequency melting furnace for recovering metal from the metal minerals having a high specific gravity sorted by the floating method. The apparatus of the present invention further comprises a mixer for mixing the residuals of silica and lime ingredients, which are non-metal ingredients, sorted by the floating method, with a solidifying agent or the like to produce cement.
