CBSE NCERT Notes Class 12 Chemistry Isolation of Elements

Extraction of Iron from oxide. Oxide ores of iron, after concentration through calcination/roasting (to remove water, to decompose carbonates and to oxidise sulphides) are mixed with limestone and coke and fed into a Blast furnace from its top. In this case, the oxide is reduced to the metal. One of the main reduction steps in this process is:

Copper - Wikipedia

The cuprous oxide is converted to blister copper upon heating: 2 Cu 2 O → 4 Cu + O 2. The Sudbury matte process converted only half the sulfide to oxide and then used this oxide to remove the rest of the sulfur as oxide. It was then electrolytically refined and the anode mud exploited for the platinum and gold it contained. This step exploits ...

Copper Oxide - Properties, Structure, Uses and Preparation

Cupric oxide is a brown colored powder while cuprous oxide is a red coloured. When an atom of the copper band is attached to an oxygen molecule, then it is cupric acid. When an oxygen atom is attached to two copper atoms, it is said to be cuprous oxide. Cuprous oxide is mostly in an active state, while cupric oxide is in the fully oxidised state.
