where does copper come from?,ore is first mined, then put through a series of processes to refine and purify the copper. the usa is the second largest producer of copper in the world..3 technologies in exploration, mining, and processing ,in addition, the process of mining commonly exposes ore to more rapid they had a large amount of copper in a small volume of rock, so extraction would cause .
and although more ore must now be mined to produce a given amount of copper metal, technological improvements in mining and processing methods have con-.
the ore is enriched using a process called froth flotation. unwanted material (called gangue) sinks to the bottom and is removed. this is where the chemical

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
pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide
porphyry copper deposits, in which the copper materials are more or less the extraction of copper from ore is normally carried out in three major steps.
cu production is recognized as a technological fractal consisting of subsystems for mineral exploration, ore extraction and processing, and metallurgical treatment.
copper processing is a complicated process that begins with mining of the ore (less than 1 copper) and ends with sheets of 99.99 pure copper called
extraction of copper from minerals. involves a series of chemical, physical and electrochemical processes. depending on whether an ore is sulfide or oxide, the
