Sep 05, 2013· Some copper ores can be converted into copper(II) sulphate solution by leaving the crushed ore in contact with dilute sulphuric acid for a long time. Copper can then be extracted from the copper(II) sulphate solution. But, in many cases, it is possible to separate the metal compound from unwanted rocky material by physical means.

Metallurgy, art and science of extracting metals from their ores and modifying the metals for use. Metallurgy customarily refers to commercial as opposed to laboratory methods. It also concerns the chemical, physical, and atomic properties and structures of metals and the principles whereby metals are combined to form alloys.
May 04, 2008· The solid was a mixture of Cu and unreacted Fe. The problem was that we couldn't exactly separate the two metals (the iron filings were picking up the copper (tried separating with a magnet), as we ground the clumps with a mortar and pestle. What I'm asking you guys is- is there any way to (fairly quickly) separate the iron and copper? Thanks!

The present work describes an investigation of a chemical process for the recovery of copper and iron from malachite ore. For the dissolution of copper and iron, H 2 SO 4 was employed as well as H 2 O 2 as an oxidizing agent. The effects of reaction temperature and time, acid concentration, liquid-to-solid ratio and agitation rate on the copper and iron percentage were investigated.

Surface mining is used to excavate ores at or close to the earth's surface ; underground and in situ mining both remove minerals from deeper deposits. Metallic minerals: include ores, such as bauxite - from which aluminum is extracted - copper, gold, iron, lead, silver, and zinc.
The ore is first crushed and milled to liberate the tungsten mineral crystals. Scheelite ore can be concentrated by gravimetric methods, often combined with froth flotation, whilst wolframite ore can be concentrated by gravity (spirals, cones, tables), sometimes in combination with magnetic separation.

The measurement of Cu, Fe, and Zn isotopes in natural samples may provide valuable information about biogeochemical processes in the environment. However, the widespread application of stable Cu, Fe, and Zn isotope chemistry to natural water systems remains limited by our ability to efficiently separate these trace elements from the greater concentrations of matrix elements.
