flotation in mining copper and gold oxide ore

  • Copper Mining and Extraction: Oxide Ores

    The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.

    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 in mining copper and gold oxide ore 」

    Copper ore divides into ore sulfide,ore oxide and mixing ore according to its oxide rate. The main process for copper ore is flotation, for refractory mixed copper ore and refractory oxide ore, normally use hydrometallurgy process.,It is a high technological enterprise

Copper ore bodies are divided into three separate groups which are native copper ores, sulphide copper ores, and oxide copper ores. Most important copper beneficiation techniques are froth flotation, gravity

  • Flotation of Gold and Gold-Bearing Ores ScienceDirect

    1/1/2016· 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 recoveries.

  • (PDF) A Review of the Flotation of Copper Minerals

    The recovery of these copper minerals by flotation or hydrometallurgy from ores, typically containing 0.5%TCu (open pit mines) and 1-2%TCu (underground mines) is of great commercial importance....

  • Froth flotation Wikipedia

    Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores". The development of froth flotation

    The oxide ore plant utilizes a standard flotation method producing a copper and gold concentrate for smelting. Tailings from the oxide ore flotation plant report to an atmospheric leach plant.

  • Iron oxide copper gold ore deposits Wikipedia

    Iron oxide copper gold ore deposits (IOCG) are important and highly valuable concentrations of copper, gold and uranium ores hosted within iron oxide dominant gangue assemblages which share a common genetic origin. These ore bodies range from around 10 million to >4,000 million tonnes of contained ore, and have a grade of between 0.2% and 5% copper, with gold contents ranging from

  • Copper ores Danafloat

    Because an ore typically has more than one copper sulphide mineral type, often a combination of sulphide flotation collectors is used to maximize metallurgical performance. These are added separately or, as is becoming common, are supplied as blended products to optimize flotation. Frothers are an important flotation reagent suite consideration.

  • Gold-Pyrite ores Danafloat

    Gold has varying modes of occurrence in sulphide ores ranging from being disseminated and interstitial in minerals such as lead and copper, in oxide ores particularly as disseminated particles, and as free milling gold or association with tellurides.
