Ore enrichment | KGHM Corporate Website

Aug 26, 2014· A mechanical process of copper ore enrichment is essential for effective smelting. The concentration level obtained at the enrichment stage makes the copper material fit for further processing at the smelter. This processing is required due to the fact that the copper ore deposits mined by KGHM in Poland contain, on average, only 1.52% of copper.

Enrichment of Ore or Concentration of Ore

The process of removal of gangue particles from an ore to increase the percentage of metal in ore is called enrichment of ore. The processes used for removing the impurities from ores depend on the difference between physical or chemical properties of the ore and of the impurities.

Uranium enrichment - Energy Education

Uranium enrichment is a process that is necessary to create an effective nuclear fuel out of mined uranium by increasing the percentage of uranium-235 which undergoes fission with thermal neutrons.Although many reactors require enriched uranium fuel, the Canadian-designed CANDU, the British Magnox reactor and the proposed Molten salt reactor can use natural uranium as their fuel.

Uranium processing - Leaching | Britannica

Uranium processing - Uranium processing - Leaching: Roasted uranium ores are leached of their uranium values by both acidic and alkaline aqueous solutions. For the successful operation of all leaching systems, uranium must either be initially present in the more stable hexavalent state or be oxidized to that state in the leaching process. Acid leaching is commonly performed by agitating an ore ...

Enriched uranium - Wikipedia

Uranium as it is taken directly from the Earth is not suitable as fuel for most nuclear reactors and requires additional processes to make it usable. Uranium is mined either underground or in an open pit depending on the depth at which it is found. After the uranium ore is mined, it must go through a milling process to extract the uranium from the ore. This is accomplished by a combination of chemical processes with the end product being concentrated …
