Waelz Process Assignment Point
The process consists of treating zinccontaining material in which zinc can be in the form zinc oxide zinc silicate zinc ferrite zinc sulphide together with a carboncontaining reductantfuel within a rotary kiln at 1000 c to 1500 c it is a process used for the extraction of zinc and lead from ores using a rotary kiln.
The rotary kiln is the main equipment for the production of zinc oxide by fire method the coke powder and other reducing agents are added to the charge taking advantage of the volatile nature of zinc metal the metal zinc vapor enters the flue gas and produces zinc oxide when it encounters oxygen under high temperature conditions.
The zinc oxide rotary kiln pulverizes the zinc charge and coking coal into particles less than 40 mesh the zinc charge and coking coal are mixed in a ratio of 1030 035 to obtain the mixture then the mixture is made into a particle mixture with effective diameter of 815mm working principle.
