    Apr 11, 2017 · Ores in which the copper occurs in the form of fine sulfide mineral particles disseminated throughout the gangue and which are treated by fine grinding and flotation. These ores are represented notably by the socalled porphyrycopper ores. Oxidized ores in which malachite, azurite, and chrysocolla are the predominant copper minerals that do ...

    Some copper sulfide ores can be partially oxidized, also influencing the selection of a reagent scheme, with the exception being a hypogene sulfide copper ore. Copper sulfide ores are normally finer grained than porphyry copper ores and require finer grinding ( 70–80% <200 mesh).

    Oct 15, 2014 · The main aim of laboratory tests was to find a relation between lithology of tested samples of ore and grinding media wear. Wear tests were performed in a laboratory mill filled with ball grinding media. Wet grinding was performed, which is typical for copper ore milling. Details of equipment used and tests data are presented Table 3.

    Lumpy ore after semiautogenous milling in Copper–Nickel ore processing at the Talnakh factory is studied. The lumpy ore is mainly presented by sizes −80+40 and −40+20 mm. The Xray radiometric separation tests of the lumpy ore prove their efficiency in production of concentrate and tailings. The strength characteristics and the Bond work index of the concentrate are determined.
