2006-2-1 · In this work, a new in situ leaching process is proposed to recover copper from an Algerian ore. The principles of soil remediation by electrokinetic process have been applied with success. Interesting extraction yields have been obtained without using both pressure and oxidant in the course of an alkaline leaching

Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction

how copper dump leaching works - sciencedirect

If copper recovery depends on (1/d p) and the copper leaching rate depends on (1/d p) 2, leaching of ROM ore in dumps should be impossible, or at least so slow and marginal as to not be profitable. And yet dump leaching of copper secondary sulphides is practiced widely, with good recoveries and at rates rapid enough to be measurable ( Yáñez

bioleaching process - mining fundamentals

Bioleaching, or microbial ore leaching, is a process used to extract metals from their ores using bacterial micro-organisms. The bacteria feed on nutrients in the minerals, causing the metal to separate from its ore. The metals commonly extracted using this process include gold, silver, zinc, copper, lead, arsenic, antimony, nickel, molybdenum
