This method is called underground mining whose types are explained below Room and Pillar Mining In this method mining is carried out in an ore deposit leaving behind some of the ore in the form of columns to support the roof and prevent it from collapsing Thus it results in the formation of spaces called rooms where the ore is excavated with pillars of ore distributed

This type of gold mining is characterized by its low cost as each rock is moved only once It also has low environmental impact as no stripping of vegetation or overburden is necessary and all process water is fully recycled Such operations are typical on New Zealand s South Island and in the Klondike region of Canada Rocker box The rocker box also called a cradle uses a riffles located

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
