Tellurium and bismuth were separated and tellurium was enriched from a low content of anode slime raw materials The recovery rate of tellurium and bismuth were % and % respectively The reduced deposition process of bismuth ions on the cathode was characterized by cyclic voltammetry in the nitric acid
Regarding bismuth there are also studies related to the use of this process in the extraction of bismuth from its ore The diamagnetic property of bismuth minerals has made it possible to separate bismuth using the magnetic separation process Krenev et al 2015
At the early stage pyrometallurgy process is commonly applied to separate and recover bismuth from Bi contained minerals or slags However this method suffers from a complicated process high energy consumption and low extraction efficiency Swayn et al 1993 ; thus pyrometallurgy can be used to process low or medium grade Bi contained minerals with
Use our notes to learn what an ore is in IGCSE chemistry Understand how a metal is extracted relative to its position in the reactivity series Learn more Home Start studying; Search In many cases the ore is an oxide of the metal therefore the extraction of these metals is a reduction process since oxygen is being removed
A simple and efficient method was proposed to selectively separate and recover tellurium and bismuth in an acidic leaching solution of tellurium−bismuth ore by Na 2 SO 3 and Fe powder Then the selective reduction mechanism was investigated by SEM−EDS XRD XPS ICP OES etc % Te in leaching solution can be reduced by Na 2 SO 3 with an excess
A comprehensive recovery process for the selective separation and enrichment of copper zinc and iron minerals from a polymetallic ore was developed which consisted of copper flotation zinc flotation and iron magnetic separation and the adsorption mechanism of the copper collector Z 200 O isopropyl N ethyl thionocarbamate was also studied in this work
The dissolution behaviors of various minerals in the tellurium bismuth ore during oxidic acidic leaching were investigated systematically in this work The Te Bi phase in the ore distributes in network shape triangular shape tree shape strip shape bulk shape sparse granule flake shape crescent etc which are closely intercalated with FeS FeS2 and
