Zusammenfassung: | The invention provides a method for refining copper from copper concentrate. The method comprises the following steps: culturing a base solution, namely adding an extracting solution, copper concentrate and sulfuric acid into a production device, stirring at a first preset speed, and then adding a raffinate to obtain the base solution; performing ultrahigh-temperature bacterium inoculation: adding an ultrahigh-temperature bacterium mother strain into the base solution, stirring at a second preset speed, and completing inoculation when the pH value reaches a preset value, so as to obtain an industrial strain; ultra-high-temperature bacteria leaching: adding copper concentrate and sulfuric acid into the industrial strains, and carrying out ultra-high-temperature bacteria leaching according to a preset solid-to-liquid ratio, so as to obtain a leachate; extracting the leaching solution, namely extracting the leaching solution to obtain an extracting solution and a raffinate; and the extraction liquid is electroly |
