copper ore not concentrated by hydraulic wash
Why copper ore is not concentrated by hydraulic washing? copper ore is usually in the form of malachite, needs to be refined through chemical method What ore is copper found in?copper is light heavy metal we used to concentrate by hydraulic washing the copper particle are noy settle downOre of copper is not concentrated by hydraulic
Why ore of copper is not concentrated by hydraulic washingCopper ore, usually in the form of malachite, needs to be refined through a chemical reaction, rather than a mechanical separation as with washingHydraulic Washing It is based on the difference in gravity of the particles of the gangue and the ore So, it is considered as a type of gravity separation During this process, an upward stream of running water is used to wash the powdered ore The lighter gangue particles are washed leaving the heavier oreConcentration of Ores | eMedicalPrep
Hydrometallurgical methods alone or in combination with flotation have mainly been applied to large tonnage operations to recover copper from low grade native copper, oxidized, or mixed oxide and sulfide ores that are not readily concentrated by flotation alone or by other means, either due to treatment costs orGravity Separation or Hydraulic Wash In this method, the ore having high specific gravity is separated from the gangue that has low specific gravity by simply washing with running water Ore is crushed to a finely powdered form and treated with rapidly flowing current of waterConcentration Of Ores
A new study, published in Communications Earth & Environment and led by BUFI PhD student Lawrence Carter, has provided important new insights into a ‘missing link’ of how porphyry copper deposits (PCDs) form It proposes how naturally occurring, copperrich fluids are transported from their magmatic source deep underground towards the Earth’s surfaceGravity Separation or Hydraulic Wash In this method, the ore having high specific gravity is separated from the gangue that has low specific gravity by simply washing with running water Ore is crushed to a finely powdered form and treated with rapidly flowing current of waterConcentration Of Ores
Some of the common methods of ore concentration are discussed below 1 Gravity separation or Hydraulic wash In this method, the ore having high specific gravity is separated from the gangue that has low specific gravity by simply washing with running water Ore is crushed to a finely powdered form and treated with rapidly flowing current ofIt is used when ore is soluble in some solvent It is explained based on following exampleLeaching of alumina from bauxite Bauxite is an ore of aluminum It contains silicon dioxide, iron oxides and titanium oxide Concentrated solution of sodium hydroxide at a pressure of 473 – 523 K and 35 – 36 bar is used for concentrating the oreConcentration of Ores | eMedicalPrep

Porphyrytype ore deposits are major resources of copper and gold, precipitated from fluids expelled by crustal magma chambers The metals are typically concentrated in confined ore shells within vertically extensive vein networks, formed through hydraulic41 If Total Copper has been determined and Residual Copper analysis is not required, proceed to Step 50 to calculate the residual copper concentration; otherwise, proceed to step 42 42 Wash the filter residue from the cyanide soluble procedureProcedure Residual Copper Soluble Analysis Assay

The ore is then ground finely before the copperbearing sulfide minerals are concentrated by a flotation process which separates the grains of ore mineral from the waste material, or gangue Depending on the type of copper bearing minerals in the ore and the treatment processes used, the concentrate typically contains between 25 and 30% copperGravity Separation or Hydraulic Wash In this method, the ore having high specific gravity is separated from the gangue that has low specific gravity by simply washing with running water Ore is crushed to a finely powdered form and treated with rapidly flowing current of waterConcentration Of Ores
The name hydraulic means “operated by the pressure created by forcing water (or) another liquid” Washing ore with water is known as hydraulic washing Gold mines make use of the hydraulic washing technique An upward stream of running water is used to wash powdered oreTABLE 1 Water use in the copper industry in Arizona and Texas, 1951 188 2 Unit use of water in the mining of copper ore, 1955 190 3 Previously published data showing unit use of water in the con centration of copper ores principally by watergravity sepaWater Requirements of the Copper Industry USGS
