COLUMN FLOTATION OF COPPER AND ZINC ORE OF THE CHESSY MINE, FRANCE

Obiettivo

Electricity saving and concentration increase in the roughing (first beneficiation step) of CU-ZN processing. In a new mine to be opened, traditional, two steps, mechanically stirred, flotation cells will be replaced by a single flotation column (one for ZN and one for CU). Production planned: 300000 t/y of concentrate. Energy consumption: 4.6 kWh/t instead of 11.2 kWh/t annual saving 2000 MWh. Grade of concentrate is improved. Investment cost is a bit lower than traditional process but overcost results for the project from progressive start up due to new technology. Same operating costs except transportation cost which is reduced.
