How do we extract minerals? - USGS

The primary methods used to extract minerals from the ground are: Underground mining; Surface (open pit) mining; Placer mining The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.

In-situ mining, which is primarily used in mining uranium, involves dissolving the mineral resource in place then processing it at the surface without moving rock from the ground. The method used depends on the type of mineral resource that is mined, its location at or beneath the surface, and whether the resource is worth enough money to justify extracting it.

The Four Main Methods of Mining - OreFlow

04/12/2019  Surface mining is a method of mining that involves removing the soil and the overlying rock on top of the mineral deposit. This method of mining gained popularity since the start of the 20th century, especially in North America where the majority of surface mining occurs. Most forms of surface mining use heavy equipment such as earthmovers to remove the overburden before bucket wheel ...

A Brief Introduction to the Types of Surface Mining Methods

Open-pit mining is a method in which an ore is removed by digging a pit in the ground, and is used to remove copper, gold, iron, as well as non-metallic minerals. It is normally used when the rock layer above the ore is too weak to allow underground tunnels. In this technique, circular steps, or ‘benches’, are dug around the circumference of the pit to remove ore from the sides. When ore ...

08/10/2019  The type of mining method used depends on the kind of resource that is being targeted for extraction, the deposit's location below or on the Earth's surface and the capacity of each method to profitably extract the resource. Each mining method also has varying degrees of safety and impacts on the surrounding environment, both of which are concerns for legitimate mining operations.

Mining - Prospecting and exploration Britannica

This method of constructing an ore body is widely used where the boundaries between ore and waste are sharp and where medium to small deposits are mined by underground techniques, but, in the case of large deposits mined by open-pit methods, it has largely been replaced by the use of block models. These will be discussed in more detail below see Surface mining). Mineral deposits have different ...
