湿法冶金通过溶解有价值的物种或金属的载体来重新组合提取有价值的物种或金属的技术。 并从所获得的溶液中回收这些有价值的物种。珍贵物种的复苏 通常需要使用技术来选择性地提取有价值的物种，将不需要的物种留在 解决方案。溶剂萃取法是将有价值的物种从废品中分离出来的一种方法。这样做的目的是 该项目是协助Soutex在以下领域使用溶剂提取过程的模拟软件 选矿和湿法冶金。 Soutex是一家为湿法冶金行业提供支持的咨询工程公司。这个 Soutex使用的模拟软件要求用户提供不容易获得的输入变量 敬Soutex。由于拉瓦尔大学在模拟溶剂萃取方面的专业知识 进程中，Soutex曾提议进行一个联合项目，以加速学习过程的模拟 用于溶剂提取的包装。更准确地说，溶剂提取模拟模块要求用户 提供待用溶剂处理的水溶液中金属物种的萃取等温线 拔牙。对于给定的溶剂萃取过程，对萃取等温线的估计需要一个 可通过均衡估计有效减少的大量实验室测试工作 随后可用于产生该过程的溶剂萃取化学反应的常量 等温线。拟议的项目应该有助于开发一种方法来生成提取等温线，通过 从最小数量的溶剂萃取试验中提取的平衡常数。

Hydrometallurgy regroups the techniques used to extract valuable species or metals by dissolving their carrying matrix and to recover these valuable species from the obtained solution. The recovery of the valuable species often requires the use of techniques to selectively extract the valuable species, leaving unwanted ones in the solution. Solvent extraction is one approach to separate valuable species from waste ones. The purpose of this project is to assist SOUTEX in the use of simulation software for solvent extraction processes in the realm of mineral processing and hydrometallurgy. SOUTEX is a consulting engineering firm that provides support to the hydrometallurgical industries. The simulation software used by SOUTEX requires the user to provide input variables that are not readily available to SOUTEX. Owing to the expertise available at Laval University for the simulation of solvent extraction processes, SOUTEX has proposed to conduct a joint project to accelerate the learning process of the simulation package for solvent extraction. More precisely, the solvent extraction simulation modules require the user to provide extraction isotherms for the metal species in the aqueous solution to be processed by solvent extraction. The estimation of the extraction isotherms for a given solvent extraction process requires a significant amount of laboratory test work that can be effectively reduced by the estimation of equilibrium constants of the solvent extraction chemical reactions that can subsequently be used to generate the process isotherms. The proposed project should help developing a method to generate the extraction isotherm by means of equilibrium constants extracted from a minimum number of solvent extraction tests.
