TRUE!
Electrolysis is used in the production of copper metal, because the electric current is used to refine the copper and remove any impurities, without melting the ore, which uses a lot more energy.
Through bioleaching, thermal decomposition, displacement, phytomining & electrolysis.
To separate Tin from Tin Ore you have to heat it to combine the compounds together. Also if you combine Tin Ore with copper it makes a bronze bar. :)
By the method of electrolysisCopper is a good conductor of electricity, and is used extensively to make electrical wiring and components. The extraction of copper from copper ore is done by reduction with carbon, but the copper produced is not pure enough for use as a conductor, so it is purefied using electrolysis.
Here is an extremely simplified version of a very complex process -In most copper mines the ore is crushed in 'ball mills' and then roasted . Some dirt is removed here. After this it is poured into large cleaning ponds. The treated ore is then put in water-filled aeration tanks containing surfactant. After this various acids are used to separate the other unwanted material from the copper.
A refinery separates copper from its ore.
Electrolysis
To separate copper from its ore, the process is called smelting. The copper and ore are heated and the copper turns to liquid which is then poured from the smelter.

Primarily by electrolysis of molten bauxite ore.

Copper ores, will be heavier than most of the background rocks, and will generally be brightly coloured green or blue. Gravity separation usually suffices to separate the ore. The metal is separated from the ore by heating in a reducing atmosphere to remove sulphides, etc. The final preparation of the metal is by electrolytic refining.
No, copper is a metal. It is obtained by mining various copper ores from underground, then smelting the ore in a very hot furnace to separate the copper from everything else in the ore.
yes )p
Ancient Egyptians
no, it needs to be purified using electrolysis for it to be pure enough to use as a conductor
