A solid element or compound which occurs naturally in the Earth's crust is called a mineral.A mineral which contains a high enough percentage of a metal 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 metal. It is a form of extractive metallurgy. In technical terms, it is called pulverization. They wash down while the heavier particles settle down on the grooves of the inclined table. Sometimes the composite was ground by hand before placed in the furnace for melting. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind. The process involves taking alumina (a compound composed of aluminum and oxygen) and placing it in large carbon-lined furnaces.

Continue to strike the rock with your sledgehammer until it’s broken up into small, pebble-sized pieces. The extracting metals low in the activity series will differ from those which are higher in the series. It is also called ore... 3. We all know that the metals exist mostly in the form of salts along with other minerals to form an ore. Grinding and Crushing The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. A crucible (usually made out of graphite or clay) is used to dip into the smelter to extract molten metal and ore. David Ferris started writing professionally in 2006 and has been published in several newspapers. A water jet is used to flow on the ground particles. The method that is used in the extraction of metal from its ore depends on the position of the metal in the reactivity series of metals. On the other hand, carbonated metal ores are heated in a vacuum for easy extraction of metals. Metals such as zinc, iron and copper are present in ores as their oxides.
