Flotation Chemistry（《浮选化学》）是全英文教材，主要内容包含矿物加工工程专业学生必须掌握的浮选英文基本知识，以及英语写作与表达的基本技能。
浮选体系中，酸、碱等化学药剂的添加及矿物溶解等，使矿浆溶液中发生大量的化学反应，而这些化学反应在浮选过程中对浮选起到至关重要的作用。因此，本书在介绍浮选基本理论的基础上，详细介绍浮选化学基础，之后分别介绍天然可浮性矿物、硫化物矿物、不能溶解的氧化物和硅酸盐矿物、微溶盐和可溶解盐矿物的浮选化学。前言下方附二维码，供学生下载专业词汇，方便学习。
本书的主要特点是理论与实践相结合，包含从基础理论到实际应用的内容，可供矿物加工工程相关专业本科生及研究生，以及从事相关专业的工程技术人员参考使用。
