Separation of indium and iron by solvent extraction
Indium is associated in trace amounts in several kinds of zinc and aluminum ores and has therefore been recovery as a byproduct in these industries Together with this metal iron is found in high concentration The present work investigates the separation of indium and iron by solvent extraction using a Replicate Two-Factor Factorial Design

Extracting a metal from its ore
Metals with low chemical activity such a gold and silver are normally found in their pure state Copper tin lead and iron are more reactive and must be heated with carbon to extract the metals Aluminum calcium sodium and other active metals are extracted using electrolysis Copper can be extracted from its ores by reduction

The Extraction of Iron
The common ores of iron are both iron oxides and these can be reduced to iron by heating them with carbon in the form of coke Coke is produced by heating coal in the absence of air Coke is cheap and provides both the reducing agent for the reaction and also the heat source

Extracting copper Extracting copper
Many metals are impure when they are extracted from their ores Impurities have to be removed Copper is purified by electrolysis In this process copper is transferred from an impure anode to the cathode of an electrolytic cell The insoluble impurities fall to the bottom The copper produced by this process is 99 99% pure copper

Extracting Minerals from Seawater: An Energy Analysis
Noble metals and refractory metals exist in seawater at the opposite side of the concentration spectrum in many cases in such minute concentrations that are impossible to determine with certainty The concentration of ions in seawater depends mainly by two factors: their crustal abundance and the existence of water-soluble species

Extraction of Zinc from Zinc Blende
c Roasting: The concentrated ore is roasted in the excess of air at a temperature of 900 degree celsius in the reverbatory furnace So the ore reacts with oxygen to form Zinc Sulphide (ZnS) and Sulphur dioxide (SO 2) which is given by the reaction below $$ce{2ZnS + 3O2-[{heat}] 2ZnO + SO2}$$
