Recovery of copper from Waste PCB boards using

Jan 01, 2021 The E-Waste contains several materials like Gold, Silver, Copper, Ironetc. Extraction of all these metals from the scrapped electrical and Electronic Products in an environment friendly manner is of utmost importance. Electro chemical, Pyrometallurgical, Hydrometallurgical and Bioleaching are the most efficient methods to extract metals.

Extraction of Copper and Zinc from Waste Printed Circuit

The recovery of valuable metals from waste printed circuit boards (WPCBs) is crucial in order to harness their economic resources, and prevents potential environmental contamination. However, selective extraction of Cu and Zn, and the co-extraction of other metals as impurities at ambient temperature using selected lixiviants such as HCl, H2SO4, HNO3, trifluoromethanesulfonic acid (TFMS), NaOH

Bioleaching of copper from waste printed circuit boards by

Feb 22, 2018 The toxicity of waste printed circuit boards (PCBs) to bacteria was considered as the major limitation in bioleaching of copper from PCBs. To reduce the toxicity of PCBs, copper extraction from PCBs was investigated using bacteria-free cultural supernatant from some metallurgical microbial consortium, whose predominant organisms were Leptospirillum ferriphilum and Sulfobacillus

Extraction Of Copper Mining, Concentration, Smelting

Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate (CaCO 3) and air in a furnace. The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper sulphide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag.
