The provided technique demonstrates a step-by-step recovery of constituent metals in black mass using specific reagents and extraction methods. Variables such as the choice of reagents, recovery techniques, the order of recovery, and the state in which the metals are recovered (sulfates, hydroxides, or carbonates) can vary. Specific procedures

The move is no doubt driven by the growing demand for energy transition metals and minerals. A report by the World Bank estimates more than three billion tons of minerals and metals will be needed to deploy wind, solar
In response to the issues arising from the disordered charging and discharging behavior of electric vehicle energy storage Charging piles, as well as the dynamic characteristics of electric vehicles, we have developed an ordered charging and discharging optimization scheduling strategy for energy storage Charging piles considering time-of-use electricity
2 天之前· Under the optimized extraction conditions, the single-stage extraction efficiency of HDES [TOP][Lid] for Co 2+ and Ni 2+ were 98.5% and 83.9%, and HDES [TBP][Lid] for Co 2+ and Ni 2+ were 96.0% and 82.9%, and Li + was enriched in the extract. FT-IR, 1 H NMR, and ESP analysis confirmed the hydrogen bond between HBD and HBA. The metal ion
While reducing EV battery waste, bioleaching facilities mean manufacturers can recover these precious metals locally, and rely less on the few producer countries.
At the same time, waste electronics filled with precious metals are piling up in landfills and in some of the world''s poorest regions — with 2.5 million tonnes added to the total each year.
Australia-based MTM Critical Metals and its US affiliate, Flash Metals USA, are scaling up a technology that extracts metals in a flash. Developed in Rice University chemist James Tour''s laboratory, the method,
Electronic waste (e-waste) presents a significant opportunity for recovering valuable precious metals (PMs) while mitigating environmental impacts. This study introduces a novel approach to e-waste recycling by utilizing electrochemical exfoliation (ECE) to produce graphene oxide (GO) from discarded dry cells, composed of graphite
As the world transitions towards more sustainable energy sources, electric vehicles (EVs) have become increasingly popular. However, the ability to store and efficiently transfer energy remains one of the main

This review systematically summarizes the current technologies (pyrometallurgy, hydrometallurgy, and direct recovery) of recovering metal resources from spent batteries and
This Special Issue "Conventional and Novel Processes for the Extraction of Precious Metals from Spent Catalyst and Electronic Equipment" will examine all these aspects. In particular, works about the most-used methods such as pyrometallurgy and hydrometallurgy for the separation of precious metals from other non-precious components will be
A new method safely extracts valuable metals locked up in discarded electronics and low-grade ore using dramatically less energy and fewer chemical materials than current methods, report University of Illinois Urbana
Researchers then extract valuable metals from black mass by dissolving it in a combination of orange peel that has been oven-dried and ground into powder, and citric acid, an acid found in citrus fruits, before letting the metals precipitate.
Our modern world is dependent upon natural resources extracted from the ground, but there could be another source of rare and valuable metals by giving our houses a spring clean.
Therefore, finding novel, green and environmentally-benign techniques for the sustainable recovery of precious metals (PMs) from e-waste has been an interesting topic of research in many industries.
A new technique offers a less energy-intensive way to recover lithium, cobalt, nickel and manganese from end-of-life lithium-ion batteries, and uses carbon dioxide for the process rather than the high temperatures or

Australia-based MTM Critical Metals and its US affiliate, Flash Metals USA, are scaling up a technology that extracts metals in a flash. Developed in Rice University chemist James Tour''s laboratory, the method, called flash joule heating, involves applying an intense subsecond pulse of electric current to chopped-up e-waste
A new technique offers a less energy-intensive way to recover lithium, cobalt, nickel and manganese from end-of-life lithium-ion batteries, and uses carbon dioxide for the process rather than the high temperatures or corrosive and hazardous chemicals traditionally associated with this activity
This review systematically summarizes the current technologies (pyrometallurgy, hydrometallurgy, and direct recovery) of recovering metal resources from spent batteries and the strategies of transforming recovered metal resources into electrode materials for various energy storage devices (lithium-ion batteries, supercapacitors, lead-acid
Considering the energy storage cost of energy storage Charging piles, this study chooses a solution with limited total energy storage capacity. Therefore, only a certain amount of electricity can be stored during off-peak periods for use during peak periods. After the energy storage capacity is depleted, the Charging piles still need to use grid electricity to meet the
To address the rapidly growing demand for energy storage and power sources, large quantities of lithium-ion batteries (LIBs) have been manufactured, leading to severe shortages of lithium and cobalt resources. Retired lithium-ion batteries are rich in metal, which easily causes environmental hazards and resource scarcity problems. The appropriate

Another promising technique for the recovery of noble/PMs from E-wastes is hydrometallurgy. This process mainly consists of two important steps including a) the leaching process of metals and b) PMs extraction from the pregnant leaching solution (PLS).
The recovery process of noble/precious metals includes 3 prominent steps including leaching, extraction and stripping. The main utilization of ILs is in the leaching or extraction steps. Some ILs (usually functionalized ILs) can be applied as both extractant and diluent.
Recovery of PMs is the driving force of sustainable development. In the past, hydrometallurgical and pyrometallurgical processes were introduced as the most prevalent techniques for the recovery of PMs from e-waste.
Disparate scientists have investigated the recovery feasibility of PMs/noble metals via hydrometallurgy and bio metallurgy, chemical leaching, incineration, smelting, grinding and pulverizing techniques , , , , .
Precious metals (i.e., gold, silver, platinum, ) can be described as chemically-inert and scarce elements with high economic value, which are being prevalently applied in jewelry, industrial processes, currency and also as investment vehicles. Table 1 enlists the physicochemical properties and industrial applications of different PMs. Table 1.
General speaking, PCBs consist of only 3–6 % of overall weight of e-waste, while they are the result of around 40 % of the obtained incomes from the recovery of PMs from e-waste , , .
