Increasing Concentration

Raw copper is enriched by separating the materials from each other and removing unwanted materials, so they go down in order to convert the copper into a more useful shape.

A substance is added to the copper to facilitate its melting process and make it melt faster. Solid lime is melted to a temperature of 1200 ° C. Some impurities are removed to form a mixture of liquid copper and iron sulfide.
