Practice of Clean Production on Electrolytical Refinement of Silver

This paper investigates the production level of enterprises to explore their potential for clean production through analyzing the present status of material balance and yielding and discharging of pollutants with taking the checking of clean production of electrolytical refinement of silver as an example. We proposed twenty Free - of/Low charge projects and executed sixteen Free -of/Low charge projects with implementation rate 80 % and accumulated investment 14,200 Yuan, obtaining an estimated economical benefits of 28,000 Yuan/Year. We planed to execute four Free- of/Low charge with anticipated investment 51,000 Yuan and economy benefits of 62,000 Yuart/Year.
