英国比利顿公司与智利国家铜公司商定建一合资企业工业应用比利顿取得专利的生物浸出技术( Bio COP)。 Bio COP法基本上是采用原生铜矿浮选精矿进行生物浸出使铜溶解 ,分离出的富硫酸铜矿浆进行溶剂萃取 -电积生产阴极铜。它与 Gencor公司 80年代开发的、现已成熟的金生物 -氧 BELITON, the British company, and the National Copper Company of Chile have agreed to build a joint-venture company, Bentlyton’s patented Bio-Leaching Technology (Bio COP). Bio COP method is basically the use of primary copper ore flotation concentrate bioleaching copper dissolution, the separation of the copper sulfate-rich pulp solvent extraction - electrowinning production of copper cathode. It was developed with Gencor in the 1980s and is now mature gold bio-oxygen
