Abstract
Pure copper is dissolved in sulphuric acid or oleum in the presence of a soluble compound of a metal electro-negative to copper such as silver or mercury, or selenium. The electro-negative element may be added to the acid and then a solvent for it, such as nitric acid for silver or mercury. When blister copper is employed as raw material, one of its impurities may be used as catalyst, the necessary solvent say nitric acid for silver or hydrochloric acid for selenium being added. If an excess of copper is employed, the electro-negative metal used and any gold or silver in the copper are deposited on the excess copper and may be recovered. The process may be employed for refining copper.
