有色金属生物冶金主要采用生物技术来对矿物中的有色金属进行富集、分离、提取和回收利用，通常由微生物来进行矿石的细菌氧化或生物氧化。生物冶金工艺成本低、污染少、资源利用率高，目前已应用于难处理金矿、铜硫化矿等。生物冶金具有超过常规处理贫矿的技术优势，正发展成为国际上有色冶金研究的热点之一。《有色金属生物冶金(普通高等教育十二五规划教材)》主要内容包括：有色金属生物冶金技术基础、冶金方法、工艺特征和工业应用(提取金、铜、镍、锌)。文中均加以简要注释，以方便自学。书后附相关专业词汇。薛济来主编的《有色金属生物冶金(普通高等教育十二五规划教材)》适用于有色冶金、冶金工程、工业生态、矿物工程、环境工程等专业的高年级本科生和研究生科研和双语教学，也可供研发人员和生产技术人员参考。
