in thiourea solution, except higher consumption of thiourea, insufficient investigation on gold leaching in thiourea solution is also the limitation[10-13]. Since gold leaching in the alkaline thiourea... for mechanism of gold leaching from ores in alkaline thiourea solution. In alkaline thiourea solution, combining the property of thiourea, the process of gold dissolving in alkaline medium may be expressed......

performance; leaching kinetics 1 Introduction Since olivine LiFePO4 (LFP) was discovered by PADHI et al [1], it got very rapid development due to its long cycle life, high safety performance and high... into the spent LFP powder can be further selectively removed by alkaline leaching, since Al can react with alkali but LFP cannot. In general, the high-concentration NaOH solution can dissolve 99% of the Al sheet......
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... conditions, the apparent activation energy is determined to be 11.157 kJ/mol, which is consistent with the values of activation energy fordiffusion model. The kinetics equation of leaching arsenic from......
focused on reductive leaching, specially in acid medium[9-14]. Based on the study of oxidative leaching in alkaline medium, the kinetics of the oxidative leaching is discussed and the effects of gas...
