|
Answer» Solution :The naturallyoccuringchemical substances in formof whichthe metalsoccurin theearthalongwithimpuritiesare called minerals.The MINERAL fromwhichthe metalcan beextractedconveniently andeconomically is calledan ore. Thus, all oresare mineralsbut allmineralsare not ores. FOREXAMPLE, ironis foundin theearth'scrustisoxides, carbonates and sulphides. Out of theseminerals of iron,theoxides ofiron are employed forextractionofthe metal. Therefore, oxides of ironare theores ofiron. Similarly, aluminiumoccurs in earth'scrustin formof twominerals, i.e.,bauxine`(Al_2 O_ 3X H _ 2 O ) `and clay` (Al_2O_3. SiO_2. 2 H _2O )`. Outofthesetwominerals, Al can beconvenientlyand economically extractedfrom bauxile.Therefore,bauxine istheoreofaluminium. |
