Explain A Suitable Method For The Extraction Of Gold
EXTRACTION OF IRON IN A BLAST FURNACE Iron is also below carbon in the reactivity series, so therefore carbon can be used to reduce it (note: reduction can also mean to remove the oxygen from a compound). This is done in a blast furnace.

Extraction - Solvent Selection
SOLVENT SELECTION. The solvent is the key to a successful separation by liquid-liquid extraction. The several criteria are: 1. Distribution Coefficient. This is the ratio (at equilibrium) of the concentration of solute in the extract and raffinate phases. It gives a measure of the affinity of the solute for the two phases. A distribution coefficient other than unity implies that the solute ...
