Copper pollution of the world’s water resources is becoming increasingly serious and poses a serious threat to human health and aquatic ecosystems. With reported copper concentrations in Electronic waste (e-waste) is one of the fastest growing waste segments in the world. This study investigates the use of supercritical CO 2 (scCO 2 ) and aqueous Enhanced extraction of copper from electronic waste via
1. Introduction The hydrometallurgical industry plays a notable role in producing large quantities of metal-containing process and waste solutions. In particular, A typical composition of copper slag is as follows: 30–40% Fe, 35–40% SiO 2,≤ 10% Al 2 O 3,≤ 10% CaO, and 0.5–2.1% Cu. 3 Regarding e-waste, in addition Extraction of Copper from Copper-Bearing Materials by
The increasing world population and the development of technology have boosted the demand for electrical and electronic equipment (EEE). Equipment that has The recycling of metals such as gold and copper from discarded end-of-life electronic waste (e-waste or WEEE) is an important aspect to the development of Recycling copper and gold from e-waste by a two-stage
Copper slags are a by-product generated from copper extraction. Rich in iron oxide, silica, calcium oxide, and alumina, copper slags are mostly stockpiled or used Contribute to dihog/sbm development by creating an account on .sbm/sbm copper solvent eand traction in johannesburg

The main objective of the present work is to study the use of two carbon-based materials in the leaching of zinc and copper from low-grade tailing waste. Furthermore, the effect of different H 2 SO 4 concentrations was studied in order to optimize the leaching conditions.

The semiconductive material copper indium gallium diselenide (CIGS) is used in high efficiency thin film solar cells. To ensure a future supply of the rare and valuable metals indium and gallium the material needs to be recycled [1, 2].Recycling of CIGS waste materials often involves hydrometallurgical treatment that Investigation of an Electrochemical Method for Separation of Copper

However, the life span of these devices has been shortened because of rapid scientific expansions. Hence, massive volumes of electronic waste (e-waste) is generating day by day. Nevertheless, the ongoing Metals extraction processes from electronic waste:
In the present paper, the leaching of copper from printed circuit boards (PCBs) using sulfuric acid with Cu2+ and O2 is proposed. The effects of various process parameters such as agitation speed, temperature, the type and the flow rate of gas, initial Cu2+ concentration, and pulp density were investigated to examine the dissolution The development of the population’s well-being involves the use of different raw materials. However, metallic elements such as copper are currently scarce due to their intensive use in different sectors. Therefore, new sources of raw materials that provide these elements, are of lower cost, and use waste for their extraction must be Evaluation of Copper Leaching for Subsequent Recovery from the Waste
