Occurrence of Metals: Metal Ores, Methods of Extraction

extraction of metalsintroduction

THE EXTRACTION OF METALSAN INTRODUCTION This page looks at the various factors which influence the choice of method for extracting metals from their ores, including reduction by carbon, reduction by a reactive metal like sodium or magnesium, and by electrolysis. Details for the extraction of aluminium, copper,

Extracting iron and copperExtracting and using metals

An ore is a rock that contains enough of a metal or a metal compound to make extracting the metal worthwhile. Most metals are extracted from ores found in the Earth's crust. Ores are often metal

extraction of metals from ores presentation

Metal extraction slides 1 Extraction of metals a describe the ease of obtaining metals from their ores by relating the elements to their positions in the reactivity series Recycling of metals a describe metal ores as a finite resource and hence the need to recycle metals, eg the recycling of iron b discuss the social, economic and

Ways to Separate Metal From OreSciencing

The process of separating a metal from its ore is known as smelting. Smelting is widely practiced today and has a long history dating back to the Bronze Age,

Extractive metallurgyWikipedia

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

Extraction of MetalsMethods of Extraction of Metals

The metal ores are found in the earths crust in varying abundance. The extraction of metals from ores is what allows us to use the minerals in the ground! The ores are very different from the finished metals that we see in buildings and bridges. Ores consist of the desired metal compound and the impurities and earthly substances called Gangue. The extraction of metals and its isolation occurs over a few major

Overview of the different methods of extraction of metals

Extraction of Metals. The separation of metals in a pure or relatively pure state from the minerals in which they occur naturally. Metals are found in the Earth either as compounds or, in the case of very unreactive metals, as the crust of the uncombined element. The rock that contains the metal is called an ore.
