  • Copper extraction - Wikipedia

    The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock. A key objective in the metallurgical treatment of any ore is the separation of ore minerals from gangue minerals within the rock.

  • Mineral processing - Wikipedia

    Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.

  • Copper Lead Concentrate Separation

    When copper-bearing minerals are to be separated from galena, the first step generally consists of the “bulk flotation” of both classes of mineral in one copper-lead concentrate by the use of reagents very similar to those employed in the lead flotation section of a lead-zinc plant.

    Recycling of electrical cable waste requires a separation between the metal and the insulating material. The objective of this work was to separate the copper from the plastic in electrical cable waste previously ground below 2 mm, using jigging, shaking table and froth flotation techniques. The effect of particle size was also analysed.

  • Introduction to Mineral Processing

    The ability to selectively float the separate minerals depends on the ore, the chemicals, and other factors. Conclusion. Gold, silver, copper, lead, zinc, molybdenum, iron, potash, phosphate, and even sand for glass are often processed by froth flotation. Without froth flotation, many of the metals and minerals used every day in our modern ...

    Single mineral flotation tests using chalcopyrite and molybdenite only showed a marginal effect of chitosan as a potential selective depressant in copper–molybdenum sulfide separation. However, since the single mineral flotation tests could not demonstrate the competitive adsorption of chitosan on the two minerals, testwork was carried out on ...

    Flotation separation of copper sulphides from arsenic minerals at Rosebery copper concentrator. ... (1995) also used pre-oxidation to separate copper sulphide minerals from arsenic minerals, but they found that arsenic minerals were more oxidised resulting in depression in the flotation of copper sulphide minerals.

    The mineralogical characteristics of enargite-bearing copper ores from the Tampakan deposit have been investigated as the means to understanding the separation of enargite from other copper sulphides (chalcopyrite and bornite). It was found that a separation of these minerals was possible after grinding the ore samples to a P80 of 90 microns; enargite tends to be ground more readily than the ...
