    In-situ Copper Recovery in Arizona - Florence Copper

    In-situ copper recovery is an environmentally responsible way of extracting copper from the ground. A low-pH solution similar in strength to vinegar slowly dissolves copper in the bedrock. At the same time this solution is being introduced into the copper ore body, it is also being drawn through the ore and extracted.

    Prior to the development of the solvent extraction-electrowinning (SX/EW) process in 1959 (see Copper the Green Metal), the only way to recover copper from an acid solution was by a process called cementation. In this process, copper was in effect "traded" for iron by contacting the copper-bearing solution with scrap iron.

    In comparison, solvent extraction with hexane (the primary solvent used worldwide) will remove all but about ½% of residual oil, uses less horse power, and requires less maintenance. It is relatively efficient and reliable, and this is one reason why solvent extraction is the primary means of separating large tonnages of oil from protein meal.
