Trans. Nonferrous Met. Soc. China 22(2012) 2261-2267 Element distribution of high iron-bearing zinc calcine in high gradient magnetic field LI Mi1, PENG Bing1, 2, CHAI Li-yuan1, 2, WANG Ji-ming1... and recover metals have been reported. A high gradient magnetic separation was proposed to remove zinc ferrite from zinc calcine according to the weak magnetic properties of zinc ferrite, which will reduce......
for soft magnetic ferrite material was developed. Using reduction lixivium from high-acid reductive leaching of zinc oxide calcine as raw solution, copper and indium were firstly recovered by iron powder... in Fig.1. Reduction lixivium from high-acid reductive leaching of zinc oxide calcine bearing high In-Fe was used as raw solution. After copper cementation and indium neutralization, some harmful......
="ChDivSummary" name="ChDivSummary">Sulfuric acid leaching of high iron-bearing zinc calcine was investigated to assess the effects of sulfuric acid concentration, liquid-to-solid ratio, leaching time, leaching... minerals such as zinc ferrite in zinc calcine dissolving at high temperatures and high sulfuric acid concentrations but not at low temperatures and low sulfuric acid concentrations.关键词:......
acid concentration, pressure, reaction time and temperature on the extraction of zinc and the dissolution of silica. Under the optimum conditions employed, up to 99.25% of zinc extraction and 0.20% silica dissolution are obtained. The main minerals in leaching residue are quartz and small amounts of undissolved oxide minerals of iron, lead and aluminum are associated with quartz. Key words: zinc......
