本文介绍了BHP Billiton公司的BioCOP（TM）工艺在智利Chuquicamata铜矿从中试规模到全规模工业示范的工程开发情况，该工艺设计年产铜2万t。BioCOP（TM）工艺是专门为处理精矿而开发的，精矿由于含有有害元素，如对环境有害的砷，不适合商业冶炼。该工艺利用在高达80摄氏度的温度下操作的嗜热微生物来浸提硫化铜精矿。铜随后通过传统的溶剂萃取和电解回收，生产高价值的铜金属产品。本文介绍了分阶段开发的重要性，以确保商业工厂设计的放大标准的正确定义。该商业示范工厂的设计和运行也被描述为“世界上第一个”利用嗜热微生物进行生物浸出以商业化处理初级硫化铜精矿。(C)2006 Elsevier B.V.保留所有权利。
The paper describes the engineering development of the BioCOP(TM) process, from pilot-scale to full-scale commercial demonstration at the Chuquicamata Mine in Chile, with a design production rate of 20000 t copper per annum.BioCOP(TM) Process is owned by BHP Billiton. The BioCOP(TM) Process has been specifically developed for treatment of concentrates not suitable for commercial smelting due to the content of deleterious elements, such as arsenic, which is harmful to the environment. The process utilises thermophilic microorganisms operating at temperatures up to 80 degrees C to leach copper sulphide mineral concentrates. The copper is subsequently recovered by conventional solvent extraction and electrowinning, producing a high value copper metal product.The paper describes the importance of staged development to ensure correct definition of scale-up criteria for commercial plant design. The design and operation of the Commercial Demonstration Plant is also described a "World First" for bioleaching using thermophilic microorganisms for commercial treatment of primary copper sulphide concentrates.
