About 80 of copper from ore is generated using flotation smelting and refining oxide ores are generally just crushed prior to further processing since leaching does not require the same small particle size as floatationChat Online
Properties of copper ores the problem minerals from which copper can be extracted to make money are called copper ores there are several copper ores but they all fall into two main categories oxide ores and sulfide ores oxide ores contain oxygen sulfide ores contain sulfur azurite malachite and chrysocolla are a few examples of oxides oresChat Online
Samples of copper ore such as malachite could be shown if available for the second question work out the concentration of copper in say testtube 3 concentration cu as cu 2 410 x 1 m 04 m work out the concentration of copper ions when 5 g of copper carbonate is dissolved and made up to 100 cm 3 of solution formula mass ofChat Online
Principal forms in which copper ores are found include native copper porphyry copper massive deposits and mixed ores native copper is simply the metal found unadulterated in nature occasionally copper is still found in its native form but more frequently it is mixed with other minerals some of which may have value themselves the amount of copper in an ore can vary from 04 percent to more than 12 percentChat Online
The mixed ore contains oxide supergene oxide and hypogene sulphide copper species respectively with the greater part of the deposit being made up of sulphide and mixed ores the oxide ore has a much higher grade than the mixed and sulphide ores but contributes less toChat Online
