How is copper extracted from a low grade ore of it?

Leaching is the process to extract pure copper from a low grade ore. Leaching is the process of extracting substances from a solid by dissolving them in a liquid, in this process the ore is dissolved in liquid but not impurities. Then the copper solution is reacted with iron to get pure copper (reduction process). C u 2 + + H 2 → C u (p u r e ...

Copper Smelting Chemistry Tutorial

Copper can be extracted from sulfide ores (usually higher grade ores) by direct smelting. The earliest evidence of copper smelting occurs in Serbian artefacts dating from around 5000 BC. Copper can be extracted from oxide ores using electrolysis ( electrowinning ) for low grade ores, or by the carbon reduction method of smelting for higher grade ores.

Innovations: Introduction to Copper: Mining & .

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. Bioleaching and phytomining are increasingly used to extract copper from low grade ores (see below). The traditional method of extraction is to heat the copper sulfide.

Copper Mining and Extraction: Oxide Ores

Copper is refined from ores in the ground, either through underground or open-pit mines. Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores.
