About 80 of primary copper production comes from lowgrade or poor sulfide ores after enrichment steps the copper concentrates are usually treated by pyrometallurgical methods generally copper extraction follows the sequence see figure below 1 beneficiation by froth flotation of ore to give copper concentrate.

According to the notions of scott 1912 and rickard 1932 the initial idea about copper smelting technology was that smelting the first copper happened accidentally in a campfire rickard based this on observation from katanga where he had found copper prills adhering to chunks of ore in a campfire made by the local population.

hopefully recent developments will also allow the use hl to process primary sulfide ores this would result in a dramatic expansion of the technology as.
