Minerals must be concentrated into deposits to make their collection economically feasible. A mineral deposit containing one or more minerals that can be extracted profitably is called an ore. Many minerals are commonly found together (e.g. quartz and gold; molybdenum, tin and tungsten; copper, lead and zinc; platinum and palladium).

Placer deposits are natural occurring concentrations of minerals and metals that are found in sedimentary rock formations. These deposits are formed through a series of geological processes that involve the movement, deposition, and alteration of minerals. They are an important source of economic minerals such as gold, silver, copper, lead, …

Guyana - Resources, Power, Mining: Guyana's most important mineral resources are the extensive bauxite deposits between the Demerara and Berbice rivers that contribute to making the country one of the world's largest producers of bauxite. There are also significant deposits of manganese at Matthews Ridge in the northwest, about …

element minerals like sulphur, copper, silver, gold, graphite etc. are found. Though the number of elements making up the lithosphere are limited they are combined in many different ways to make up many varieties of minerals. There are at least 2,000 minerals that have been named and identified in the earth crust; but almost all the

For example, Metal Ores, Coal, Oil, Sand, etc. For the purpose of definition, Minerals are specifically defined as naturally occurring Inorganic Substances which are found in solid-state. Minerals have a well-defined chemical structure, formula and crystal structures. Different Minerals vary in their physical properties such as color, density ...
