CHINA MINE ENGINEERING

The beneficiation process of Mirador Copper Mine comprises bulk copper-sulfur flotation-rougher concentrate regrind-copper-sulfur separation, in which the column+cell combined process is adopted for cleaning operation. The flotation column utilizes the EFD gas-water mixture flotation columns manufactured by ERIEZ Tianjin and the column size is 5m×12m, where 3 columns are installed for Cleaning Ⅰ and 1 column for Cleaning Ⅱ. Since it was put into production in July 2019, this type of flotation column has shown a good separation effect and a strong adaptability to various ore types thanks to its high degree of automation, and is in full conformity with the cleaning operation requirements of Mirador Copper Mine.
