separation of copper from ore

copper extraction and purification - chemguide

2015-7-26 · Extracting copper from other ores. Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution.

Separation of copper from chalcopyrite using hydrochloric ...

1998-2-24 · In the separation of copper from a high grade copper ore such as chalcocite CuS 2, covellite CuS or bornite Cu 5 FeS 4, a dry method is generally adopted. Because of a high energy cost, the dry method is not employed for the separation of copper from a low grade copper ore such as chalcopyrite (CuFeS 2). It is well known in the art that copper ...

The separation of arsenic from copper in a Northparkes ...

2007-10-19 · In order for the high-arsenic regions of the Northparkes copper–gold orebody to be beneficiated economically, tennantite ((Cu,Fe) 12 As 4 S 13) present in the ore needs to be rejected to enable copper concentrates to meet the typical smelter penalty level of 2000 ppm As. Using a composite sample of high-arsenic drill cores from Northparkes it was possible to
