Spectrophotometric Determination of Copper

Branicoda Copper Mine is considering opening up a new mining site. The geologists feel that there might be a lot of copper at this new site. Samples of ores taken from the new site were sent to Water Wagon Laboratories to be tested. The ore samples were recently added to a sulfuric acid solution to bring out the Cu2+ (copper(II) ions) into ...

Sulfuric acid injection in copper heap leaching | LEWA

The leaching reagent (dilute sulfuric acid) is sprayed through sprinklers on top of the heap pile and allowed to trickle down through the heap, where it dissolves the copper from the ore. The resulting solution of sulfuric acid and copper sulfate is collected in a small pool. Copper concentration is around 65%. Next step is solvent extraction.

Copper Sulfide - an overview | ScienceDirect Topics

The leaching of copper sulfide and copper oxide ores entails partial dissolution to cupric sulfate with sulfuric acid and iron sulfate. The presence of pyrites in many ore deposits, and its reaction with water and oxygen to form iron sulfate and sulfuric acid, creates an important source of acid.
