  • Extractive metallurgy Wikipedia

    Extractive metallurgy is a branch of metallurgical engineering wherein process and methods of extraction of metals from their natural mineral deposits are studied The field is a materials science, covering all aspects of the types of ore, washing, concentration, separation, chemical processes and extraction of pure metal and their alloying to suit various applications,An oil refinery or petroleum refinery is an industrial process plant where petroleum (crude oil) is transformed and refined into useful products such as gasoline (petrol), diesel fuel, asphalt base, fuel oils, heating oil, kerosene, liquefied petroleum gas and petroleum naphtha Petrochemicals feedstock like ethylene and propylene can also be produced directly by cracking crude oilOil refinery Wikipedia1 The Uses of Chromium in the Metallurgical Industry Chromium is hard, often mixed into steel to make a hard and corrosionresistant alloy, mainly used for refining stainless steel, heatresistant steel, and various electric heating element materials When stainless steel encounters corrosive substances, a fine and solid chromium oxide film will be formed on the surface to5 Uses of Chromium | Uses of Chromium in Industry
