Document Type and Number:
Japanese Patent JP7292002
Kind Code:
B2
Abstract:
To reduce the discrepancy between an estimated amount of exudation of copper and an actual amount of exudation thereof.SOLUTION: A copper ore evaluating method includes: a first step in which copper is exuded from copper ore with sulfuric acid solution, to measure an amount of exudation of copper A; and a second step B in which copper is exuded from copper ore with solution containing iron (III) ions, to measure an amount of exudation of copper B. The first to second steps may be conducted in an arbitrary order.SELECTED DRAWING: None
