Study on the separation process of limonite with Lead and Zinc

In view of the ore properties of limonite with lead and zinc in Guizhou, gravity separation, magnetic separation, chloride reduction roasting-magnetic separation, gravity separation-magnetic separation-chloride reduction roasting-magnetic separation were studied. Experimental results show that the gravity separation-magnetic separation-chloride reduction roasting-magnetic separation process is more effective to deal with the ore,in certain experimental conditions, access to the lead concentrate grade of 25.00% and recovery of 45.61%,iron concentrate grade of 64.08%, a good indicator of recovery of 84.74%, volatilization of lead and zinc during roasting process can be used wet recovery.
