Color Matching of Electroplating Precious Metals

Recycling of Precious Metals from E-scrap

Recovery of gold and other valuable metals from electronic scrap involves a complex metallurgical flow sheet and requires state-of-the-art recovery technologies that are available in large-scale, integrated smelter and refinery operations. At the end of their use, electronic and other electrical product scrap offer an important recycling potential for the secondary supply of gold and silver...

Electroless Deposition and Electroplating of Metals

Recovery of Metals from Electroplating Wastes

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...

Recovery of precious metals from waste streams

As there is a high potential for microbe-based technologies to bring the recovery of metals from waste streams to an ecologically friendly and financially reasonable level, it is worth to invest efforts into the advancement of these biotechnologies in the future.
