From Ore to Finished Product - Copper

2021-1-21  Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

US5403382A - Method and apparatus for copper

Copper is extracted from ore by crushing copper bearing ore followed by heap leaching with sulfuric acid and then moving the resulting solution to a tank containing scrap iron and agitating the solution to precipitate the copper. The tank possesses at least one gate for retaining the scrap iron, which gate is disposed above the bottom of the tank and has a mesh of at least one square inch.

2018-3-1  Furthermore, in case of the high pyritic feed type (SN.1 and SN.4), copper grade is relatively poor compared with the low pyritic feed especially in the first cells which might originate from the single stage addition of the chemical agents. Floatation of pyrite in the high pyritic ore through these cells causes reduction in copper grade.

Rcovery of gold in pyritic ores - Mine Engineer.Com

2013-1-13  The most difficult particles to gravity concentrate are the fines, and 75 microns to 2 microns are definitely very fine. So, even if the ore were ground to 2 microns, it may not be recoverable using current gravity technology. That appears to leave froth flotation as still the best method of recovering the gold from pyritic ores.
