Novel Hydrometallurgical Approach to Recover Precious Metals
Process for the Production of Electrolytic Grade Cu, Ni, Co, Mn from the Purified Leach Liquors of E-Waste
Tags: CSIR Labs, India, Energy & Environment, Science & Exploration
CSIR-National Metallurgical Laboratory [CSIR-NML]: This technology involves a process for producing high-purity metals such as copper (Cu), nickel (Ni), cobalt (Co), and manganese (Mn) from purified leach liquors derived from e-waste. It utilizes a hydrometallurgical approach to recover these metals through electro-winning, with optimized conditions based on parameters like current density, pH, and temperature. The process is designed for the efficient recycling of valuable metals from waste PCBs and LIBs, offering an environmentally friendly solution for metal extraction. This innovation supports industrial recycling practices, reducing e-waste and contributing to sustainable resource management.
