摘要
“富矿精开”是贵州省委、省政府贯彻落实党中央、国务院支持贵州在新时代西部大开发上闯新路的重要战略部署,富集的矿产资源是贵州突出的比较优势,贵州要紧密围绕“富矿精开”,大力推进矿产资源的开发利用。矿物加工及化学选矿是“精深用矿”的重要技术依托,物理化学知识体系中基础核心部分—热力学基础理论和研究方法对矿物加工过程有着非常重要的作用。在矿物加工工程专业物理化学课程教学中,需要紧密围绕热力学的基础理论、方法和工具,结合“富矿精开”大背景和地区矿产资源优势,将热力学中的ΔG^(θ)-T图和E-pH值图等原理及使用方法传授给学生,同时也要求学生要扎实掌握;并以高硫铝土矿、锰矿、煤矸石、富钾页岩、硫化矿、金矿石和稀土矿(渣)等为例,阐述ΔG^(θ)-T图和E-pH值图在焙烧和浸出等实际化学选矿过程中的应用,能提升学生进行理论联系实际的能力和“富矿精开”的专业素养。
“Fine Development of Rich Mineral Resources”is an important strategic deployment of the Provincial Party Com-mittee and Government of the Guizhou Province to implement the support of the Party Central Committee and the State Council for Guizhou’s innovative path of the Western Development in the new era.Guizhou should closely promote the development and utili-zation of mineral resources around the"rich ore and refined development"and the comparative advantages of enriched mineral re-sources.Mineral processing and chemical beneficiation are important technical support for“deep mining”,and the thermodynamic basic theories and research methods,which is the fundamental core part of the knowledge system of physical chemistry and plays a very important role in mineral processing processes.In the physical chemistry teaching of mineral processing engineering,it is nec-essary to closely focus on the basic theories,methods,and tools of thermodynamics,combined with the background of“Fine Devel-opment of Rich Mineral Resources”and the advantages of regional mineral resources,and integrate the principles and usage meth-ods ofΔG^(θ)-Tand E-pH diagram of thermodynamics,while also requiring them to have a firmly grasp them.Taking high sulfur bauxite,manganese ore,coal gangue,potassium rich shale,sulfide ore,gold ore,and rare earth ore(slag)as examples,this article elaborates on the application ofΔG^(θ)-T and E-pH diagram in practical chemical beneficiation processes such as roasting and leaching in order to enhance students’ability to connect theory with practice and their professionalism and competence in“Fine Development of Rich Mineral Resources”.
