<p>PROBLEM TO BE SOLVED: To provide a separation method capable of separating mineral concentrate into mineral concentrate having a high copper content concentration and mineral concentrate having a high molybdenum concentration.SOLUTION: A separation method includes a heating step and a separation step. In the heating step, rough concentrate obtained by pulverizing and selecting yellow pyrite crude ore containing molybdenum is mixed with an elemental sulfur and then heated to 350°C-450°C. In the separation step, the rough concentrate obtained in the heating step is crushed to perform floatation method so as to be separated into first flotation concentrate recovered at a preceding stage of a process of the floatation method, and second floatation concentrate recovered at a subsequent stage of the process.</p> |
