Copper extraction refers to the methods used to obtain copper from its ores The conversion of copper consists of a series of physical and electrochemical processes Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors

Mineral resources are classified as metallic such as iron and tin ores or nonmetallic such as fossil fuels, sand, and salt Ore is part of a metal yielding material that can be economically extracted from a mineral typically containing two parts: the ore mineral, which contains the desired metal, and waste mineral material gangue

All ores are minerals but all minerals are not ores? It is so because metals cannot be extracted from minerals in a convenient way E g : Aluminum metal is found in both minerals: clay and bauxite
