A method for recovering zinc from slag derived from lead smelting comprises subjecting the slag to a leaching step under conditions in which zinc is dissolved into solution and silica present in the slag dissolves and reprecipitates in a form that is readily separable from liquid, and recovering zinc from the solution. The slag may be subjected to leaching in at least two stages in which in a
#0183;#32;A series of characterization of zinc slag have been carried out, including XRD and XRF. The results showed that the contents in slag of zinc and cobalt were % and %, respectively. And it is significant to recover the smelting slag. First, zinc slag was leached with sulfuric acid to obtain the leaching solution containing multiple ions.

#0183;#32;Leaching and recovery processes for zinc and copper from brass slag by sulfuric acid were carried out and iron and aluminum were also precipitated as hydroxides in addition to silica gel. The factors affecting the performance and efficiency of the leaching processsuch as agitation rate, leaching time, acid concentration and temperature were separately investigated.
#0183;#32;The low recovery amounts at low temperature is due to the low reactivity of slag, while as the temperature increases, the nonmatching of zinc and copper recovery is due to partial hydrolysis of slag till 35#176;C but increasing the temperature to 70#176;C seriously decreases zinc recovery due to possible polymerization and hydrolysis.

#0183;#32;A series of characterization of zinc slag have been carried out, including XRD and XRF. The results showed that the contents in slag of zinc and cobalt were % and %, respectively. And it is significant to recover the smelting slag. First, zinc slag was leached with sulfuric acid to obtain the leaching solution containing multiple ions.
At First, The pyrometallurgical recovery of zinc from slag samples was carried out, and parameters affecting recovery processes such as time, temperature, and flux percentage were studied.
With the rising cost of zinc reaching historic levels, more emphasis is being placed on technologies to increase the efficient utilization of zinc. One area targeted for increased efficiency is inhouse recycling of metallic zinc industrial wastes. The largest consumer of zinc is the hotdip galvanizing of steel. Large amount of zinc slag containing more than 50% zinc, are accumulated during
