How much metal does the ore contain? ? World

Copper ore does not contain pure copper, but either a copper-sulphur-iron compound (chalcopyrite) or a copper-sulphur compound (chalcocite). The metal must first be separated from such minerals by means of multi-step metallurgic processes. In many cases these processes are so complicated that they account for up to 30 per cent of the metal price.

Some observations on copper yields and ore grades

The average copper content of ore deposits is usually below the average yield of the ore accessed in the early years of production. The initial grades of new mines have not declined over the past forty years, and there has been no perceptible tendency for the average grade of porphyry deposits brought into production to decline over time.

background about determination of copper

The average grade of copper ores in the 21st century is below 0.6 percent copper, with the proportion of ore minerals being less than 2 percent of the total volume of the ore rock. Copper-containing rock, or copper ore, holds only a small percentage of copper. Most of the rock is unwanted material, typically referred to as gangue.
