Phase transformation involved in the reduction process of magnesium oxide in calcined dolomite by ferrosilicon with additive of aluminum

Autor: Ma Hongzhou, Wang Zhixian, Wang Yaoning, Wang Dingding

Publikováno v: Green Processing and Synthesis, Vol 9, Iss 1, Pp 164-170 (2020)

Metal magnesium is mainly produced from the calcined dolomite by the silicothermic production. However, in this process, the reduction temperature is higher while the reaction speed is slow, which results in higher energy consumption and serious envi

Zinc and lead recovery from jarosite residues produced in zinc hydrometallurgy by vacuum reduction and distillation

Autor: Li Jin, Ma Hongzhou

Publikováno v: Green Processing and Synthesis, Vol 7, Iss 6, Pp 552-557 (2018)

Jarosite residues in zinc hydrometallurgy are considered as hazardous waste as they contain heavy metals such as Zn and Pb. A novel vacuum reduction and distillation process has been put forward to recover Zn and Pb from jarosite residues. Four main

Optimization of the treatment process of zinc leaching residue by using the response surface method

Autor: Ma Hongzhou, Xie Hongwei, Wang Yaoning, Yan Chao

Publikováno v: Green Processing and Synthesis, Vol 7, Iss 5, Pp 460-463 (2018)

The decrease in the zinc volatilization rate is usually due to the liquid phase, which is typically generated in the rotary kiln. The response surface model was built to analyze and explore the effects of carbon content, basicity, and holding time on

Statistical analysis and optimization of recovering indium from jarosite residue with vacuum carbothermic reduction by response surface methodology (RSM)

Autor: Ma Hongzhou, Yan Chao, Wang Yaoning, Xie Hongwei

Publikováno v: Green Processing and Synthesis, Vol 6, Iss 2, Pp 211-216 (2017)

Vast jarosite residue was produced from traditional zinc hydrometallurgy process in China. It is necessary to recover valuable metals from the jarosite residue. Indium is the one of them. Recovering indium from jarosite residues with carbon reduction

Pretreatment of arsenic-bearing gold ore with microwave-assisted alkaline leaching

Autor: Ma Hongzhou, Yan Chao, Wang Yaoning

Publikováno v: Green Processing and Synthesis, Vol 5, Iss 3, Pp 269-273 (2016)

In this paper, the removal of arsenic from arsenic-bearing gold ore through air oxidation and sodium hydroxide leaching with microwave irradiation was studied. Firstly, single-factor experiments were carried out. The results indicated that the remova
