The ores from which silver and gold are recoverable by flotation divide themselves naturally into two general processing classes: ores in which the valuable minerals are those of the base metals, the precious metals being incidental constituents, and ores in which the gold and silver are of primary importance, the base metal minerals, if present, being of little or no value. The first class
In the gold flotation recovery process, foaming chemicalsmust be added to the slurry. Commonly gold recovery foaming chemicals usedcalyptus oil, camphor oil, cresylic acid, higher alcohols and No. 2 flotation oil 2# oil.
In the early stages of the operation the overall gold recovery achieved averaged 61 and copper recovery was 74 . The plant was experiencing problems in the leach, adsorption, elution and electrowinning sections mainly as a result of the presence of copper in the ore.

This flotation is not favorable for gold, as both cyanide and high lime have negative effects on gold recovery, and gold recovery ispromised for production of a marketable grade coppergold ore. Recent research work carried out withanic acids has indicated that in the presence of high lime, gold recovery can be enhanced by adding small quantitiesanic
Gold recovery from massive sulRde copper}gold ores is usually much lower than that of porphyry copper}gold ores, because very often a large portion of the gold is associated with pyrite. Normally, gold recovery from these ores does not exceed 60 . During the treatment of copper}gold ores containing pyrrhotite and marcasite, the use of Na 2
Froth flotation is a widely used separating technique for the recovery of Cu and Au in porphyry copper gold ores. In these ores, chalcopyrite and gold are the main valuable mineral/metal phases, with pyrite being the key sulphide gangue mineral. However, in these ores gold is mostly associated with pyrite rather than the copper minerals.
The flotation method is a technique widely used for the recovery of gold from gold containing copper ores, base metal ores, copper nickel ores, platinum group ores and many other ores where other processes are not applicable. Flotation is also used for the removal of interfering impurities before hydrometallurgical treatment i.e. carbon prefloat, for upgrading of low sulphide and refractory
Recovery of gold as by product from the base metals industries. gold is often associated with chalcopyrite in ore deposits, and efforts are therefore obviously made at the mine to maximize the recovery of both gold and copper, either usingbination of gravity and flotation techniques, or flotation alone. inquiry

GOLD RECOVERY BY FLOTATION. A test on a sample, crushed to pass a screen of 120 holes per linear inch, containing $37 gold and 4.8 copper, gave a recovery by flotation alone of 90 of the gold and 98.5 of the copper, but left $8 gold in the tailing. The concentrate carried 44 insoluble matter, which could be reduced by re treatment.
25/06/2020· Flotation of a pyrite concentrate frombined zinc tailings streams of the Main Lensposite was reground to approximately 25 microns K80. Cyanide leaching of the Main lens material yielded an additional 8.0 of copper recovery, 32.9 of gold recovery and 20.7 silver recovery. Similar treatment of the zinc tailings streams of the
Copper sulphides are selectively floated from pyrite ores at high pH's in excess of 11. It is less clear how the free gold behaves under these conditions. In addition, for extra gold recovery, further collectors are added, such as the monothiophosphates, which are known to be selective gold collectors.
Both quicklime and hydrated lime are widely used in the flotation or recovery of non ferrous metals, including copper, zinc, nickel and lead bearing ores. Lime is used extensively in the recovery of gold and silver. Ores, either run of mine, milled, autoclaved or roasted,
An increase of gold and copper recovery was found in the <20 µm fraction to a high level of statistical significance. For the 20 <38 µm size range the copper recovery increased to a high level of significance, whereas the increase in gold recovery in this fraction was to a lower statistical significance.
