secondary sulfide mineralization. Also, there are ores that contain significant gold and silver values, these ores are processed through the beneficiation plant with a rate of 8,500 tonnes per day using a flotation concentrator. Gold and silver values not recovered in the copper flotation concentrate report to the tailing storage facilities (TSF).

In order to overcome the difficulty of extracting gold from gold-bearing sulfide ore by cyanide process, flotation was adopted based on mineralogical analysis. Mineralogy shows that gold particles are of superfine structure and mainly enclosed by sulfide ores. Primary gold-bearing sulfide ore is fine-grained pyrite and arsenopyrite. The paper describes the effects of ratios …

Typically, freemilling ores are defined as those where over 90% of gold can be recovered by conventional cyanide leaching or some combination of flotation and cyanidation, while refractory ores ...

For silver-containing gold ores, silver gets leached along with gold in cyanide or thiosulfate. After stripping, the enriched strip solution goes through electrolysis to recover gold and silver. The cathode-containing gold and silver is sent to the refineries to be cast as doré bars. Silver is separated from the gold-silver doré bars by ...

Globally, copper, silver, and gold orebody grades have been dropping, and the mineralogy surrounding them has become more diversified and complex. The cyanidation process for gold production has remained dominant for over 130 years because of its selectivity and feasibility in the mining industry. For this reason, the industry has been adjusting its methods …

Copper is most commonly present in the earth's crust as copper-iron-sulphide and copper sulphide minerals, for example, chalcopyrite (CuFeS2), bornite (Cu5FeS4) and chalcocite (Cu2S).

ucts, namely, flotation and gravity concentrates. The main valuable component of an ore sample of any deposit is gold. The gold content should be in the range of 11.11–12.87 g/ton. The main rock-forming minerals of the original ore are quartz (60.1%), quartz–chlorite–micaceous aggregates (3.8%), and car-bonates (7.1%).

Froth flotation is a physicochemical process that is used to separate fine mineral particles from aqueous suspensions by selective attachment of some types of minerals to air bubbles. Froth flotation is the most important mineral processing technology for the production of valuable mineral concentrates from which metals and minerals are obtained. Practically all metals in …

Since many free gold containing ores have a silver content, this collector may be applicable at other sites. Liberated native gold ores Klimpel and Isherwood (1993) showed the sensitivity of the collectors S-701 and F-)00 as a function of pH on free gold recovery. The results of gold recovery can be seen in Figure 4.

Gold flotation is used for refractory gold-bearing ores and products containing 1-3 g/t of gold. During flotation processing of polymetallic ores, gold is simultaneously recovered in appropriate concentrates (copper, zinc, etc.). The extraction of gold into copper and zinc concentrates is from 30 to 35 %, the remaining gold goes into
