high grade ores are therefore cheaper to process ores need to be purified before being reduced to the metalthis adds to the expense. Extractive metallurgy is the art of extracting metals from their ores and refining them. This book deals with the processes, operations, technologies and processing routes of manufacture of metals from their ores (i.e. the (production) extraction of metals from ores, concentrates (enriched ores), scraps and other sources and their refining to liquid metals before casting or to solid metals In modern metal ore extraction, the most common technique is open-pit mining. electrorefining) and the production of metals in powder form. Types of The general principles of extraction of metalsExtraction of metals is the process by which metals are isolated from their ore. The entire scientific and technological process used for isolation of the metal from its ores is known as metallurgy routes of extractive metallurgy, i.e. electrowinning) and for the purifica tion of metals, (i.e. The EXTRACTION OF METALS Metallurgy: The entire scientific and technological process used for isolation of the metal from its ores is known as metallurgy. ores of some metals are very common (iron, aluminium) others occur only in limited quantities in selected areas. Objectives After reading this lesson, you will be able to: differentiate between minerals and ores; recall the occurrence of metals in native form and in combined form as oxides, sulphides, carbonates and chlorides; The extraction and isolation of metals from ores involve the following major steps: Concentration of the ore, Isolation of the metal from its concentrated ore, and Purification of the metal. In much the same manner as open-pit coal extraction, soils and vegetation are removed from the mine site. The extraction of metals is basically a The process of extracting the metals from their ores and refining them is calledmetallurgy. Bulk ore is then extracted by blasting charges to loosen the bedrock EXTRACTION OF METALS. The choice of the process depends upon the nature of the ore and the type of the metalIn this lesson, you shall learn about some of the processes of extraction of metals from their ores, called metallurgical processes.
