Recovery of Metals from Electroplating Wastes
نویسنده
چکیده
Disposal of metal finishing wastes is one of the most critical industrial waste problems in the United States today. Recent legislation greatly restricts the discharge of most heavy metals to watercourses and future discharge regulations may further restrict their release to the environment. Furthermore, interest in developing possible methods for reclaiming metals from plating waste streams is on the rise. This is due to (a) the ever-increasing cost of metals used in plating operations, (b) concern over the reliability of foreign sources of supply for certain metals, and (c) higher costs both for treatment and land disposal sites to handle the potentially hazardous metal sludges.

The concept of microbiological leaching have played a greater role to recover valuable metals from various sulfide minerals or low grade ores during the middle era of twentieth century and that continued till the end of the century. Slowly, due to depletion of ore/minerals, and implementation of stricter environmental rules, microbiological leaching process has been shifted for its application ...
