Electrochemical methods for materials recycling RSC

Overall, antimony is one of the most important critical minerals to consider recycling and recovering due to its scarcity. Electrochemistry has been shown as advantageous to the recovery of antimony from spent ry furnace to produce secondary bullion low in antimony content by con trolled addition of reducing agent and a slag high in antimony.

Antimony (III/V) removal from industrial wastewaters: treatment of

However, significant concentrations of antimony ([Sb] ≥ 25–50 mg L −1) remain in effluent from the process, which require removal in compliance with Korean wastewater regulations. Antimony(III/V) removal via co-precipitation with iron has been considered with optimal pH, dose and kinetics being determined.The cross-section of the CP wire scrap was analyzed using electron-probe microanalysis (EPMA, JXA-8230, JEOL, Japan), as shown in Fig. 2, and the results showed that the CP wire scrap was a needle-like material with a cross-sectional length of approximately 500 μm.The innermost area showed a columnar Fe needle, and the Recovery of tin from tin-coated copper-clad steel wire scrap

Antimony Geoscience Australia

Antimony is a silverly, lustrous grey metal that exhibits poor heat and electrical conductivity. It is relatively soft, measuring only 3.25 on Moh's scale of mineral hardness. Known as "stibium" in classical Latin, antimony is represented by the chemical symbol Sb. A member of the arsenic group of elements, antimony is commonly found inCopper scrap is often classified according to its source: (1) direct or “home scrap”, which is the scrap generated at the smelter/refinery and has the highest purity, usually recycled internally at the plant; “new scrap” is generated at downstream metal fabricators, e.g. trimmings, boring and croppings, which also usually is recycled at the Copper Recycling ScienceDirect

Efficiency and mechanisms of antimony removal from wastewater

Treatment of antimony (Sb) mine drainage is generally regarded as a priority issue for regulatory authorities. In the study synergetic removal of Sb(V) from wastewater using cheap scrap iron inoculated with iron-oxidizing bacteria (IOB) and sulfate-reducing bacteria (SRB) was proposed.When the antimony smelting slag contains Pb ~1.2%, Zn ~6.9%, and Sb ~1.4%, the metal recovery of Pb, Zn, and Sb after fuming and volatile process will be 95%, 88%, and 60%, respectively. Meanwhile, the coal consumption is ~0.3 t per ton antimony smelting slag, when the pulverized coal with 59.92% fixed carbon is utilized as The Recovery of Pb and Zn in Antimony Smelting Slag

A Review on Pyrometallurgical Extraction of Antimony from

Antimony is classified as a critical/strategic metal. Its primary production is predominated by China via pyrometallurgical routes such as volatilization roasting—reduction smelting or direct reduction smelting.

Silver Recovery from Scrap and Low-Grade Residue emew

Up to 95% of silver and copper has been recovered from electrolysis of spent solar cells in research studies, and a standard silicon solar cell module of 60 cells contains approximately 6 g of silver. At a 95% recovery, 5.7 g (0.183 ozt) of silver at $15.79 USD/ ozt equates to $2.89 USD/module.Recycling e-waste has been a significant topic for environmental protection and also for resource recovery. Waste tantalum capacitors (WTCs), widely existing in discarded small appliances, are rich in high quality tantalum (Ta) resources. However, recovering Ta from WTCs is difficult due to the tightly covered mold resin. This study Recovery of Tantalum from Waste Tantalum Capacitors by
