GCSE CHEMISTRY - Extraction of Copper - Thermal ...

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.

Nickel: An introduction - Explain that Stuff

Nov 03, 2019· Physical properties. Nickel is a typical metal: solid at everyday temperatures, reasonably strong and tough, malleable (easy-to-work), and ductile (capable of being pulled into wires). It's fairly easy to polish, a reasonably good conductor of heat and electricity, and quite magnetic as well. In its strength and toughness, it's similar to iron (though less magnetic), though it's much more ...
