Extraction of Metals. Extraction of Copper.. Copper is sometimes found as native metal.. Copper ores include copper(II) oxide and copper(II) sulfide. Copper(II) oxide can be reduced by reaction with carbon.. Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable.

Block of Copper – Official Minecraft Wiki

Oxidation []. Copper blocks have four stages of weathering (including the initial unweathered state). They can oxidize over time, while lightning bolts and axes can remove the oxidation layer on copper blocks.. Oxidation of copper blocks relies only on random ticks.Rain or water does not accelerate oxidation, and covering copper blocks with other blocks does not prevent oxidation.
