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.,interpretation of flotation data for the design of …,chief metallurgist, western metals, burnie, tasmania, australia . and . jose dioses . separation may be a simple bulk float (i.e.pyritic gold ores, some copper ore with negligible pyrite) or as is the case for polymetallic ores, a complex three stage sequential separation (ie copper, lead, zinc).
as in all mining operations, the ore must usually be beneficiated. the processing techniques depend on the nature of the ore. if the ore is primarily sulfide copper minerals, the ore is crushed and ground to liberate the valuable minerals from the waste minerals. it is then concentrated using mineral flotation. the concentrate is typically then sold to distant smelters, although some large mines have smelters,extraction of copper from copper pyrite | grade 12 science,the principal ore of copper is copper pyrite and copper is extracted from this ore. the different steps in extraction of copper are: crushing and concentration: the ore obtained from mines are broken down into small piece by jaw crusher and then pulverized. the ore being sulphide ore is concentrated by froth floatation process.
how copper is mined. copper is found alongside many other types of ore. it can be found near gold, silver, zinc, lead, and other types of metal deposits. when mixed in with other ores, copper is not usually found in great abundance. until the development of the modern copper mining process, it was typically a byproduct of mining for other metals.,which one of the following is the chief ore of copper?,the principle ore of copper is copper pyrite (c u f e s 2 ) and copper is extracted from this ore.
the extraction of metals from ores involve three major steps: 1. concentration of the ore, 2. isolation of the metal from its concentrated ore, and. 3. purification of the metal. for sulphide ores, froth floatation method is used to concentrate the ore by removing gangue particles from it.,name the chief ores of aluminium and zinc? - brainly.in,a) a gas turns into a liquid as it releases energy. b) a liquid becomes a gas as it absor. bs energy. c) two white solids are added to a colorless liquid, and a colorless liquid remains. d) two colorless liquids are added together, and a colorless liquid and a green solid remain.

copper ores. the main copper sulphide minerals are chalcopyrite (cufes2) chalcocite (cu2s), covellite (cus), bornite (cu5fes4), tetrahedrite ( (cu,fe)12sb4s13) and enargite (cu3ass4). the largest source of copper is from porphyry ore deposits in which one or a combination of,native copper - wikipedia,native copper is an uncombined form of copper that occurs as a natural mineral. copper is one of the few metallic elements to occur in native form, although it most commonly occurs in oxidized states and mixed with other elements. native copper was an important ore of copper in historic times and was used by pre-historic peoples.
