湿法冶金提纯废弃焦粉的热力学研究

湿法冶金反应过程中的热力学研究可以揭示反应过程中反应热变化规律、反应进行的可能性以及反应自动进行的条件。选用云南某地产出的废弃焦粉作为研究对象,对其采用湿法冶金两段浸出过程进行了热力学分析。研究结果为采用湿法冶金方法降低废弃焦粉灰分含量的实验研究提供理论依据。所获得优质焦粉经造球成型后,作为冶金、化工(主要指电石)等行业替代还原剂使用具有较好的应用前景。 The thermodynamics study of the leaching process can reveal the changing regularity of reaction heat,the feasibility and the necessary condition of reacting automatically.Analyze the abandoned coke powder from Yunnan Province.It was studied with high pressure in acid leaching and alkaline leaching,and the two thermodynamic analysis of the reaction.The results show this study can provide theoretical base for lowering ash content in abandoned coke powder.The coke is molded after removing the ash,which can be used as reducing agent in matallurgy and chemistry(mainly calcium carbide) industry
