Project
The recovery of valuable metals from mineral waste streams through innovative hydrometallurgical processes.
Chromium (Cr) containing slag from metallurgical industries such as steel, alloy and nonferrous alloy production is classified as a hazardous waste. Its disposal is a major environmental concern. According to the Flemish environmental legislation, Cr could not exceed limit values, 1250 mg/Kg for reuse of the materials as or in a construction material. Also, Cr could become a critical resource in Europe and secondary resources can be interesting. The objective of the study is to develop further knowledge with regard to the recovery of chromium from metallurgical slags using innovative hydrometallurgical processes.
