摘要
The invention relates to a method for the extraction of metals from copper sulphide and/or copper iron sulphide ores with microbiological- and chemical-type leaching steps for dissolution of the metals, which comprises the following steps: 1) In a conversion step, prior to the leaching steps, the ores are converted to covellite, pyrites and admixed sulphides by the addition of sulphur, and 2) copper and other metals, noble metals and rare earths contained in the reaction product are extracted.
