For natural gas, this means separating the useful methane called pipeline gas, from ethane, propane, butane, hydrogen sulphide, water vapour, hydrates and pentane. The purpose of a Blast Furnace is to reduce the concentrated ore chemically to its liquid metal state. Thus, isolation of crude metal from concentrated ore involves two major steps: Conversion to oxide. The gases are valuable and are not regarded as waste. Extraction of Crude Metals from Concentrated Ore The concentrated ore is usually converted to oxide before reduction, as oxides are easier to reduce. Isolation of metal from the concentrated Ore involves the refining of metals from the compounds it is found with to its original state. The emphasis is not on specific metal but on key fundamentals which govern the extraction of these metals. Hence the ores are converted to oxides, so it is ideal for reduction. The crude metal obtained by the preceding processes is generally contaminated by arsenic, sulphur, iron, nickel, cobalt and antimony, and sometimes with silver or gold. Crude metals cannot be used by industry at this stage because of inferior physical, chemical, and mechanical properties. 70.9k VIEWS. the removal of impurities from crude metals.
