Leaching of a pyrite-based ore containing copper

2020-6-24  This manuscript reports the mechanistic and thermochemical aspects of the oxidative dissolution of an ore based on pyrite, which hosts sulfides of copper and silver. As mentioned previously, pyrite is one of the most stable sulfides, so it is important to design a route involving strong oxidants able to dissolve the minerals present in the ore (i.e., a solution with a high ORP).

ROLE OF STARCH AND METABISUPHITE ON PURE PYRITE

2011-8-19  approximately 53 μm ore sample in 2.5 liter cell for pyritic copper ore study. An agate mortar and pestle was used for grinding the pure pyrite sample while ore sample was ground with a ball mill prior to each test. In these experiments the effects of depressant type and dosages at two different pHs for flotation behavior of pyrite were investigated. The flotation flow-sheet with copper ore is given in Figure 2.

Clay and pyrite in copper concentrate VS frother

2021-6-30  It is common practice that during flotation of porphyry copper ores containing clay minerals,the copper froth becomes highly flocculated after xanthate collector additions,resulting in dry froth that is difficult to remove. To prevent froth dryness,a collector with frothing properties in combination with two or more frothers is used.
