    Depending on the type of copper-bearing minerals in the ore and the treatment processes used, the concentrate contains copper from around 25% for chalcopyrite (CuFeS 2) ores, increasing to over 50% for bornite (Cu 5 FeS 4) and chalcocite (Cu 2 S) ores. The concentrate is then smelted to float off as slag the iron oxides and iron sulphides.

  • Effect of HPGR Breakage on Metallurgy – Minerals Engineering

    2016-05-17  Micro-cracking is also known as micro-fracturing. It is the phenomenon internal fracturing of particles due to the extreme pressure exerted by the rolls in the compression zone of higher pressure grinding rolls. It has also been noted that particle size reduction by compression only, as practised in the HPGR, generates residual micro-cracks in the crushed product. See Figure 4 and

  • Hydraulic fracturing in mining - CSIROpedia

    BackgroundResearch HistoryIndustry ApplicationThe CSIRO TeamNational and International ProfileHonours and AwardsHydraulic fracturing involves producing and extending fractures in rock by injecting a fluid under pressure into a section of a borehole. The fluid pressure produces tensile stress in the rock at the borehole wall, causing a fracture to start. The fluid then enters the fracture and opens and extends it deep into the rock. Hydraulic fracturing provides a way of growing fractures from a single initiation point and extending them to 50 metres and moSee more on csiropedia.csiro.au

    At some Australian mines, the copper is leached from the ore to produce a copper-rich solution which is later treated to recover the copper metal. The ore is first broken and set out on leach pads where it is dissolved by a sulfuric acid solution to leach out the copper. The copper-rich solution is then pumped to the solvent extraction plant to separate the copper as a copper complex. This is ...
