METHOD OF LEACHING COPPER FROM COPPER SULFIDE ORE AND METHOD OF EVALUATING IODINE LOSS CONTENT OF COLUMN LEACHING TEST OF THE COPPER SULFIDE ORE

摘要

A method of leaching copper from a copper sulfide ore which includes adding a potential adjustment agent for lowering a potential of a leaching solution obtained after leaching copper from the copper sulfide ore by using iodide ion and iron (III) ion, the leaching solution being stored in a tank for storing the leaching solution.
