【摘要】 提出了浸出剂的浸出能力和浸出容量的概念,以及浸出过程的理论浸出率的计算公式;根据化学热力学基本原理,提出了浸出状态图的概念,并提出依据浸出状态图中的浸出溶液相边界线所确定的数据来计算最大理论浸出率和估计浸出剂的浸出能力与容量的思路;在此基础上初步探讨了氧化铜碱性浸出的最佳基本工艺条件。更多还原

【Abstract】 The conception of leaching capability and leaching capacity of leaching agent is introduced.The formula of theoretical leaching rate of leaching process is presented.Based on principles of chemical thermodynamics,a diagram of leaching state is proposed.A method of using the data along the leaching solution phase boundary on the state diagram to calculate the maximum theoretical leaching rate and estimate the leaching capability and capacity is suggested.Based on these conceptions and method, the best processing condition of alkaline leaching process of copper oxide is discussed tentatively.更多还原
