Evaluation of the Processing Opportunity of Galvanic Production Sludges with Nickel Recovery

摘要

Recycling and storage of galvanic production sludges requires significant costs and they are strictly regulated by environmental documents. At the same time, the sludges contain a significant amount of non-ferrous metals, including nickel, which are preferable to extract. To evaluate the extracting nickel possibility from the sludges and selecting a method for their processing, it is necessary to study the chemical, phase, fractional material composition.
