摘要： An object of the present invention is to provide a method of copper leaching without reducing the growth of iron-oxidizing bacterium and the iron-oxidizing capacity when leaching copper from a copper sulfide ore with the use of a sulfuric acid solution to which iron-oxidizing bacteria and silver have been added.The present invention provides a method of leaching copper from a copper sulfide ore, characterized by comprising adding a naturally occurring nitrogen-containing organic component to a leaching solution upon copper leaching from a copper sulfide ore with the use of, as the leaching solution, a sulfuric acid solution to which iron-oxidizing bacteria and silver have been added is provided.
摘要翻译：本发明的目的是提供一种铜浸出方法，而不会减少铁氧化细菌的生长，并且在从硫化铜矿石中浸出铜时使用铁氧化性硫酸溶液添加了细菌和银。本发明提供了一种从硫化铜矿中浸出铜的方法，其特征在于包括使用作为浸出溶液的铜从硫化铜矿中浸出的铜，将浸出溶液中的天然存在的含氮有机成分加入到浸出溶液中提供了添加了铁氧化细菌和银的硫酸溶液。
