Extraction of Iron: Iron, Fe, is extracted from its metal oxide in the Blast The calcium oxide reacts with the silicon oxide impurities forming a calcium silie, and therefore can not be extracted from their ores using carbon reduction methods.
Calcium carbonate appears as white, odorless powder or colorless crystals. Practically insoluble in water.Occurs extensive in rocks world-wide. Ground calcium carbonate (CAS: 1317-65-3) results directly from the mining of limestone. The extraction process keeps
extraction of sodium from its ore How is sodium extracted from its ore Answers Sodium is not generally "extracted from its ore" to be recovered and used. Most of the sodium we consume is used in the form of sodium compounds, like table salt (NaCl, or sodium

The diagram below shows the extraction of sodium metal using the Downs cell. Study it and answer the questions that follow: Explain why in this process the sodium chloride is mixed with calcium chloride.
Extraction of metals The History of Metals. Metals have been used by people for many thousands of years. Gold and silver, found as native metal, were usedto extract a metal Industrial mineral- either has some direct practical use, or take part in some industrial process Gems and precious stones are an exception to industrial metals as they do have a direct ‘practical’ appliion but
Calcium has a higher melting point than strontium, because1.Correct reference to size of ions/proximity of electrons(For Ca) delocalised electrons closer to ions / positive ions / atoms / nucleusOR ions / positive ions / atoms are smallerOR ion / positive ion / atom or it has fewer (electron) shells / levels2.
