Star Trace Copper leaching agent may be dissolved copper minerals are many kinds of leaching agent, but actually only water, sulfuric acid, ferric sulfate solution, ammonia solution and chloride solutions in industrial applications are used. The most commonly used copper leaching agent is sulfuric acid. Containing quartz and more acidic copper oxide, generally preferable to sulfuric acid leaching, not only because sulfuric acid inexpensive, but also because of the acid sulfuric acid leach ore consumes less. Containing alkaline gangue higher copper oxide, liquid ammonia leaching is generally used. Mixed copper sulfate andferric sulfate is appropriate mixture of extraction, sulfuric acid is mainly dissolved copper oxide minerals, iron sulfide minerals are dissolved copper. When dealing with some metallic copper-containing materials, can also be used ammonia leaching with sulfuric acid. The method has been applied to industrial production or reach semi-industrial pilot phase methods are mainly sulfuric acid leaching, ammonia and chloride leaching medium leaching.
