前言 硫化铜矿的生物浸出,在工业界已为人们所了解,其技术也被认为是可行的。 用生物浸出技术从硫化铜精矿中提金,已在实验室和中间试验工厂中得到验证,但由于过去10年间铜市场不稳定,导致迄今仍然没有人胆敢去建设一座工业化规模的硫化铜精矿生物浸出提铜厂。然而,这项技术却被人们成功地转用到硫化物金矿提金上。 用生物浸出从难处理金矿中提金,不但具有显著的经济效益,而且有利于环境保护。因此,在不久的将来,我们便可看到有几个工业规模的生物浸出提金厂建立起来,这些工厂是用搅拌槽浸出精矿,用堆浸处理矿石。
Preface The biological leaching of copper sulphide ores is well-known in the industry and its technology is considered viable. The leaching of gold from copper sulfide concentrates using bioleaching techniques has been demonstrated in laboratories and pilot plants, but because of the unstable copper market over the past decade, no one has so far dared to build an industrial-scale copper sulfide concentrate Mine biological leaching of copper plant. However, this technology has been successfully diverted to gold sulfide gold extraction. Biodiesel leaching from refractory gold deposits not only has significant economic benefits, but also benefits the environment. Therefore, in the near future, we will see the establishment of several industrial leaching gold leaching plants that leach concentrate from a stirred tank and treat the ore by heap leaching.
