Bornite (Cu 5 FeS 4) – according to quantity, bornite is the second ore mineral in the motherlode after chalcocite. It can be found in all lithological types of ore. In sandstones, the average percentage share of this mineral varies from % of volume, in slates – %, whereas in dolomites one can

process mineralogy in mineral processing [6−19]. In recent years, mineral detection technology has been used to reduce the risk of designing new circuits and to detect and correct the low efficiency of flotation and leaching circuits; in practice, it is used to optimize processing operations in mines with different deposits [5,9−10].
The objectives of this test work are to demonstrate that the Bornite mineralized materials are amenable to the production of highgrade copper concentrates using traditional mineral processing techniques and to determine the hardness and grindability of the mineralization.

The Ag + released from silverbearing bornite was enriched on the surface of the mineral, owing to the formation of Ag 2 S. During the bioleaching process, Ag + can be regenerated by the oxidation of Ag 2 S with Fe 3+ ; thus, chalcopyrite can be continuously leached when it is silvercatalyzed.
(pyrite, chalcopyrite, chalcocite and bornite) and iron oxide phases (magnetite, hematite and goethite). A study was initiated on various ore deposits and also on samples representing various processing streams of pilot plant batches such as flotation circuits (concentrate and tailings) and leaching circuits (POX/CIL residue and CIL residue).
