Jan 01, 2016 Flotation of Copper–Gold Ores. For the bulk flotation of copper minerals and gold from supergene copper ores, it is normal practice to add a xanthate as the primary collector and dithiophosphate as a secondary collector (Bulatovic, 1997). This combination gives satisfactory results in respect of copper concentrate grade and copper and gold

About this site
Jan 01, 2016 Today, flotation is commonly used in the processing of primary copper–gold ores to produce a copper concentrate containing gold as a co-product, where the gold is recovered as a byproduct of copper smelting and refining (La Brooy, 1992). The gold is usually discrete and either free, associated with copper sulfides or associated with iron

17.7 Flotation of Gold-Containing Copper Ores. The floatability of gold from gold-containing copper gold ores depends on the nature and occurrence of gold in these ores, and its association with iron sulphides. Gold in the porphyry copper ore may appear as native gold, electrum, cuproaurid and sulphosalts associated with silver. During the
Copper Sulfide Flotation Mineral Processing & Metallurgy
Apr 13, 2016 Flowsheet for treatment of Copper Sulfide ores rich inminerals such as chalcopyrite with gold and silver as well as arsenopyrite. The above flowsheet is designed for the treatment by flotation of copper as chalcopyrite with gold and silver values. The ore, ranging from 60-65% silica, with pyrite, arsenopyrite, and calcite with 3 to 4% copper.
Estimated Water Requirements for the Conventional
Figure 1 is a generalized diagram of a conventional copper flotation plant from the point where ore first enters the circuit to the production of concentrate and tailings. To prepare ore for the flotation process, run-of-mine ore, which may contain from about 2 to 5 percent water, by weight, when mined, is

Eliminating Copper from Gold Ore

Jan 01, 2016 Flotation. Certain gold ores, mainly those containing sulfides, arsenides, or tellurides, are best treated by producing a flotation concentrate (Anderson, 1980, Jones and Woodcock, 1984, King, 1982). This is almost always the case in treating refractory gold ores, where the refractory nature of the ore is due to sulfide mineral species.
