Enriched copper ores (copper concentrates) contained an average of 19% and were extractable. Since certain copper ores (malachite, azurite, chrysocolla and to some extent chalcocite and cuprite) are water soluble, the dissolved copper was precipitated with scrap iron to produce copper sediments with a concentration of 55-65%.

Copper recoveries are 97-98% for high grade (40%) and 96% for low grade (28%) concentrates. For a full-scale plant treating 40% concentrates and producing 200,000 t/y copper via solvent extraction and electrowinning the capital cost is estimated to be US$225 million with an operating cost of US$0.09/lb Cu.

Copper ore enrichment involves mechanical processing which enables an effective management of the extracted ore. As a result, the concentrate contains the amount of copper that can be processed further in a smelter. This process is necessary due to an average 1.52% content of copper in the exploited Polish deposits.

Abstract: The copper oxide ore is high oxidation ratio and the high combination ratio with a low grade of Cu 0.71%. Copper concentrate of Cu 15.02% with a recovery of 38.55% was obtained by flotation. The optimum acid leaching conditions were investigated. Effects of lixiviant concentration, solid-to-liquid ratio, leaching time were investigated.
