Extraction of sulphidic copper ores - by leaching and application of an electrical potential at the ore-electrolyte interface

摘要

In the extraction, sulphidic Cu ores, or concentrates are treated by leaching and the interface reaction which det. the dissoln. in the leaching medium, is activated by the formation of an electric field between ore surface and electrolyte. Pref. electrodes are dipped into the ore-electrolyte. Pref. electrodes are fed with a current.
