Membrane treatment technology can be used for reutilization of advanced treatment of waste water from lead-zinc smelting by the test,the paper analyzes and investigates the affecting factor of stable operation of membrane treatment technology and determines each process parameter to supply reference to engineering design.

There Was a kind of lead slag in Yunnan which contains zinc and indium,but subjected to the metallurgy technology,they were unable to be recovered but stocked before.

Lead slags sometimes contain metal high and the fitted conditions were not eligible, so some plants take order with lead slag lately and make largeness abandon.

Therefore,the recovery and utilization of lead slag can save precious resources,increase the comprehensive utilization ratio of raw material,raise economic benefit and reduce environmental pollution.
