A molecular extraction process for vanadium based on tandem

2024.3.23 Conventional hydrometallurgical approaches (e.g.,: solvent extraction, ion-exchange, or adsorption) separate V (V) 21, 22, 23 but suffer from limitations, including low affinity and selectivity,...

Separation of vanadium and chromium by selective adsorption by

2022.12.15 The separation and purification of V (V) can be achieved by selective adsorption from high vanadium low chromium solution (real vanadium leachate).

The extraction of vanadium from titanomagnetites and other sources

2020.1.15 Vanadium is usually extracted from ores, concentrates and slags by roasting with sodium carbonate or another sodium salt to convert vanadium into water

Step-Adsorption of Vanadium (V) and Chromium (VI) in the

2020.4.14 In this paper, separation and recovery of vanadium (V) and chromium (VI) from a leaching solution was investigated by adsorption of vanadium (V) with

2024.6.1 This paper systematically summarizes the current vanadium extraction technology from converter vanadium slag, covering roasting, direct leaching, sub-molten

Vanadium ore resources of the African continent: State of the Art

2023.6.1 The African continent hosts significant and economically attractive V resources, which include all types of natural vanadium ore deposits, from the

Efficient Separation and Recovery of Vanadium (V) from

2022.2.2 The extraction efficiency of vanadium remained more than 75% with the increase of the pH value, which can realize the selective extraction and separation of

Flowsheet of vanadium leaching plant at Kabwe, Zambia

Vanadium occurrences associated with laterite, bauxite, and phosphate ores. The economically most significant vanadium sources in Africa are associated with

Rapid Vanadium Extraction from Roasted Vanadium

A H 2 SO 4 –H 2 O 2 system was developed to enhance the efficacy of vanadium extraction from roasted vanadium steel slag. The optimum parameters and the behavior of vanadium extraction were investigated

High-Efficiency Smelting Separation of Vanadium Titanium
