  • Extraction of Metals (Metallurgy) – Overall Science

      The extraction of the metals from the calcined or roasted ore consists of two steps ie, removal of earthy impurities and reduction of the ore to metal The different methods applied for carrying out the concentration of ores are useful to separate only a part of gangue and the ore   for economic extraction is called a metal ore Economic extraction means that the cost of getting the metal out of the ore is sufficiently less than the amount of money made by selling the metalGCSE CHEMISTRY Extraction of Metals What is a   An ore is any naturallyoccurring source of a metal that you can economically extract the metal from Aluminium, for example, is the most common metal in the Earth's crust, occurring in all sorts of minerals However, it isn't economically worthwhile to extract it from most of these mineralsextraction of metals introduction

  • Extraction of Crude Metal from Concentrated Ore

      Every ore is extracted from the mines with the sole purpose of collecting a particular metal The ore is mined and then sent to the refining chambers There are several processes involved in concentrating the ore of a metal This concentrating part starts with pulverization of the big ore chunks in the jaw crushes or ball millsIt is in the blast furnace that extraction of iron occurs The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such as slag What happens in the Blast Furnace? The purpose of a Blast Furnace is to reduce the concentrated ore chemically to its liquid metal Extraction of Iron Metallurgy Blast Furnace and An ore is a rock containing enough valuable mineral to make it worth extracting In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (02%) Copper minerals are found in over one hundred varieties, although only a Processes extraction, mining, smelting, refining
