A Multi-step Process for the Cleaner Utilization of Vanadium-Bearing Converter Slagrinding, sieving and magnetic separation steps was firstly utilized to recover metallic iron from the vanadium-bearing converter slag. Then a calcification roasting–acid leaching process was developed to recover vanadium from the vanadium slag, forming vanadium-bearing solution and vanadium tailings

A Novel Approach for Pre-concentrating Vanadium from Stone Coaloped techniques to extract vanadium from stone coal are all confronted with environmental problems. In order to solve those problems, an innovative process for pre-concentrating vanadium from stone coal was designed. Firstly, the environment-friendly Fe.O. is selected as a capturer of vanadium.

Recovery of Scandium by Leaching Process from Brazilian Red Mudgestion with to obtain an aluminate solution and then remove impurities by the precipitation. For each 1 ton of alumina produced, 1–1.25 tons of red mud is generated in the Bayer Process. Red mud is mainly composed of iron, silicon and titanium oxides, but rare earth elements (REEs) can also be foun

Selective Precipitation of Th and Rare-Earth Elements from HCl Leach Liquoripitation process was realized by using oxalic acid and selectivity of process was provided with the addition of oxalic acid at different volumes. The concentration of oxalic acid and settling duration were selected as parameters. The pH change of leach liquor was controlled during the experiments.

Experimental Study on the Treatment of Zinc-Containing Rotary Hearth Furnace Dusthe processes of water leaching and addition of NaOH to the filtrate produced by the water leaching process. Water leaching experiment showed that almost all K and Na contents entered the filtrate, while the Zn content in the filtrate was reduced by 7%, and the Cl was reduced by 16%. The experimental
