Copper is a good conductor of electricity and heat therefore is a useful metal. It is easily bent into another shape yet is rigid enough to make water pipes and tanks. It doesn't react with water.
Copper can be extracted from copper-rich ores by heating these ores in a furnace. This is known as smelting next the copper is purified by electroysis. Copper can also be gotten from solutions of copper salts by electrolysis or by displacement from scaro iron.
During the process of electrolysis the positive copper ions move towards the negative electrode and form pure copper metal.
However the mining of so much copper means that we are running out of copper-rcih ores. So, new methods have been found to extract less copper-rich ores.
Copper can be extrcated from:
- Low grade ores (ores that contain small amounts of copper)
- Contaminated land by phytoming or by bleaching.
