Learn MoreIn most cases, the thin-layer process was used where crushed ores (80% − in) were stacked in heaps of 3–8 m height after agglomeration and sprayed at flow rates of 6–40 L·hour −1 ·m −2 with 15–90 days duration for copper oxides and 10–18 months for sulfides. Of note, 80%–85% copper extraction was commonly achieved.
Learn More· The sulphide of calcium is easily obtained and manufactured on the ground where the mill is situated. The articles required for this purpose are brimstone (worth about four cents per pound) and burned lime. The sulphide is formed only from caustic lime, consequently more is obtained from fresh burned lime. Of this a certain quantity is charged into an iron kettle, water …
Learn MoreCopper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper-in-concentrate (usually 27–29% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite, sphalerite or galena. Chalcocite …

Coarse crushed ore is ground in a two-stage grinding circuit that comprises of an open loop semi-autogenous (SAG) mill and an overflow ball mill in closed circuit with hydrocyclones. The ore is reduced to an 80% passing size of 75 μm. The
Learn MoreIn the treatment of copper sulphide ores, recoveries in the mid 90 `s into a saleable copper concentrate grade can be achieved through crush- grind-and froth flotation processes as the flotation collectors available are very selective to the copper mineral and over a wide particle size range. Such an approach is not possible in the case of hard rock tin ores where the main …
