Zinc concentrate is the result of a flotation process after the zinc ore has been mined and milled. Zinc concentrate is an intermediate product used as raw material in the production of zinc metal. The zinc ore contains ***5% zinc whereas the concentrate typically contains approximately *5% zinc, 6.5% iron and *2% sulfur together with other elements at much lower levels.



By percentage, zinc concentrate normally contains zinc sulfide (*0% to *5%), iron sulfide (7.0% to *2%), lead sulfide (3.0% to 5.0%) silica (2.5% to 3.5%), and cadmium sulfide (0.*5% to 0.*1%). The zinc production process involves roasting the concentrate at approximately **0 °C.
