Ore dressing method for metal sulfurized ore

The characteristic of ore dressing method for metal sulfurized mineral containing Cu, P, Zn and arsenopyrite, lies in that the portland cement is used as inhibitor to inhibite lead and arsenopyrite to sort the sulfurized mineral. By using said method to inhibite arsenopyrite, the produced copper con...

Zusammenfassung:	The characteristic of ore dressing method for metal sulfurized mineral containing Cu, P, Zn and arsenopyrite, lies in that the portland cement is used as inhibitor to inhibite lead and arsenopyrite to sort the sulfurized mineral. By using said method to inhibite arsenopyrite, the produced copper concentrate ore contains Cu 30-35%, As 0.1-0.2% and Fe 12-14%; lead concentrate ore contains Pb 80-85%, As 0.1-0.16% and Fe less than 15%; the zinc concentrate ore contains Zn 50-55%, As 0.08% and Fe 13%. Advantages: small environment pollution, high grade of concentrate ore, and being an ideal ore dressing method for multi-metal sulfurized ore.
