A METHOD FOR RECOVERY OF COPPER AND MANUFACTURING METHOD FOR COPPER ELECTROLYTE USING ZINC CONCENTRATE

摘要

PURPOSE: A method for recovery of copper and a manufacturing method for copper electrolyte using zinc concentrate are provided to simultaneously leach the zinc of zinc concentrate and collect copper. CONSTITUTION: A method for recovery of copper comprises next steps. Zinc concentrate is input in the precipitate undiluted solution including copper to form a first precipitate(S100). The first precipitate is input in the refinement undiluted solution including copper in order to form a second precipitate(S200). The average granularity of the zinc concentrate is 1~10μm or less. A precipitation step operates for 6~10 hours. The precipitation step operates in 75~100°C or less.
