Types of Copper Deposits in the World

23-5-2019Copper deposit grades are usually expressed as a weight percentage of the total rock For example 1 000 kilograms of copper ore containing 300 kilograms of copper metal has a grade of 30 percent When metal is at a much lower concentration it may be described in terms of parts per million However with copper grade is the common convention
