摘要
热力学是物理化学课程的重要组成部分,可用于计算体系能量的变化和判断给定条件下反应能否发生等.矿物加工工程专业的物理化学课程的教与学需紧密围绕热力学的基础理论、方法和工具开展,结合地区矿产资源优势,熟练掌握热力学中的ΔGθ-T图的原理及使用方法.结合铁矿石、铝土矿、煤矸石和富钾页岩等的资源加工利用实例,介绍了ΔGθ-T图在解决焙烧作业工程实际问题中的应用.
Abstract
Thermodynamics is an important component of physical chemistry courses,which can be used to calculate changes in system energy and determine whether a reaction can occur under given conditions.The teaching and learning of physical chemistry courses in mineral processing engineering should closely revolve around the basic theories,methods,and tools of thermodynamics,combined with the advantages of regional mineral resources,and proficiently master the principles and usage methods of thermodynamic ΔGθ-T diagram.Combined with examples of resource processing and utilization such as iron ore,bauxite,coal gangue,and potassium rich shale,the applications of ΔGθ-T diagram in solving practical engineering problems on roasting operation.
