Most Common Metal Ores. Aluminum is one of the most common elements in the Earth's crust and is found in a variety of silicate ores, which are often a type of clay. As the minerals become weathered they are broken down into hydrated aluminum oxide, which is known as bauxite. Bauxitetoaluminum refinement is a rather expensive process and,...

Origin of Mineral Resources. Stratabound ore deposits in lake or oceanic sediments. When hot groundwater containing valuable metals scavenged along their flow paths enters unconsolidated sediments on the bottom of a lake or ocean, it may precipitate ore minerals in the pore spaces between grains in the sediment.

Extraction of Metals. What is a Metal Ore?. A solid element or compound which occurs naturally in the Earth's crust is called 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.

ore, metalbearing mineral mass that can be profitably mined. Nearly all rock deposits contain some metallic minerals, but in many cases the concentration of metal is too low to justify mining the ore. Ores are usually found concentrated in deposits with a definite gradation of metal concentration from the ore to the surrounding rock.
