In ancient times mining and mineral processing were very primitive and the main method used to extract ores was digging by hand. Mining is largely divided into surface and underground mining. Minerals are often found in river beds, beach sands and other sandy areas. These are known as alluvial deposits.

 — Mining on the Moon is a complex task that will require the use of high-tech methods and equipment. NASA relies on private companies, which the agency believes are better able to cope with mineral mining challenges than cumbersome government agencies. Below are some techniques and concepts that can be used to mine lunar minerals. …

 — Tin minerals are transported by rivers and streams and are deposited in alluvial or eluvial settings, where tin ore can be easily extracted through simple mining methods, such as panning or sluicing. Placer tin deposits are found in many parts of the world, including Southeast Asia, South America, and Central Africa.

quarrying which aim at extracting the mineral from the earth. Solid mineral exploration involves a vast number of activities which include geophysical exploration using gravity methods for dense/heavy metals like Ba, Cu, Pb, Au, Pt; magnetic methods for magnetic minerals like magnetite (Fe 3 O 4) and pyrite (FeS 2

Africa is the world's most mineral-rich continent endowed with abundant metallic and non-metallic minerals and gemstones. Africa's mineral wealth is attributable to its "favorable" geology and multiple tectonic events that affected the Precambrian rocks known worldwide to contain the bulk of many of the world's valuable mineral deposits.

Minerals can be classified into three main types based on their formation processes: igneous, sedimentary, and metamorphic minerals. Igneous Minerals: Igneous minerals form from the solidification of molten material called magma or lava.When magma cools and solidifies within the Earth's crust, it forms intrusive igneous rocks, and the minerals that …

 — The gold particles are often very small and finely disseminated throughout the conglomerate rock, and mining methods such as underground mining are used to extract the gold. Carlin-Type Deposits: Carlin-type deposits are a unique type of gold occurrence that is found in Nevada, USA, and some other parts of the world.

The mining process is used to separate rock or ore from surrounding rock. There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. The method used depends on the type of mineral resource that is mined, its location beneath the surface, and whether the resource is worth enough money to justify extracting it.
