J. Cent. South Univ. (2018) 25: 1904-1913 DOI: https://doi.org/10.1007/s11771-018-3880-y Recovery of antimony from antimony-bearing dusts through reduction roasting process under CO–CO2 mixture gas... and Springer-Verlag GmbH Germany, part of Springer Nature 2018 Abstract: This paper mainly investigated the antimony recovery from antimony-bearing dusts through reduction roasting process after the dust......
acid solution under normal atmosphere. Using the stone coal obtained from Kaili of Guizhou Province, China, as raw material, the process parameters, such as roasting time, roasting temperature, sulfuric acid addition volume and the leaching with water for the calcine, were investigated. The results show that when the stone coal is firstly treated by low temperature sulphating roasting......

Kinetics study of leaching arsenic from Ni-Mo ore roasting in dust mixture of hydrochloric and sulfuric acidsHOU Xiao-chuan(侯晓川)1, 2, YANG Yun-de(杨润德)1, LI He(李贺)1, ZENG-li(曾理)2, XIAO Lian-sheng(肖连生... of leaching arsenic from Ni-Mo ore roasting dust was investigated. The effects including leaching temperature, particle size of the smelter dust, stirring speed, the coef？cient β (the molar ratio of sodium......
J. Cent. South Univ. (2012) 19: 1808-1812 DOI: 10.1007/s11771-012-1212-1 Extraction of metals from a zinc smelting slag using two-step procedure combining acid and ethylene diaminetetraacetic acid... University Press and Springer-Verlag Berlin Heidelberg 2012 Abstract: A two-step leaching method in combination of acid and ethylene diaminetetraacetic acid disodium (EDTA-Na2) was applied to extract metals......
to now, there are no reports on the leaching kinetics of roasting ore from Dechang bastnaesite [13-19]. Sulfuric acid solution was chosen as the lixiviant in the present work and the leaching kinetics... of the overall reaction was calculated as 9.977 kJ/mol. The value of the activation energy clearly indicates that the leaching of RE from the roasting ore in sulfuric acid liquid system is most likely......
