A drum hoist (steel wire rope visible) and motor. In underground mining a hoist or winder [1] is used to raise and lower conveyances within the mine shaft.Modern hoists are normally powered using electric motors, historically with direct current drives utilizing Ward Leonard control machines and later solid-state converters (), although modern large hoists use alternating current drives that ...

The hammer and pick, two basic tools traditionally used in mining for breaking rock, together form a main heraldic symbol of mining and miners. It is also used to mark the location of mines on maps. In other locations, the pickaxe and shovel fill the same purpose. The following outline is provided as an overview of and topical guide to mining:
Depressants inhibit the flotation of one mineral or minerals while activators enable the flotation of others. Examples of these include CN −, used to depress all sulfides but galena and this depressant is believed to operate by changing the solubility of chemisorbed and physisorbed collectors on sulfides.

Surface gold mine with haul truck in foreground, in Kalgoorlie, Australia. Mining in the engineering discipline is the extraction of minerals from the ground. Mining engineering is associated with many other disciplines, such as mineral processing, exploration, excavation, geology, metallurgy, geotechnical engineering and surveying.
Artisanal mining can include activities as simple as panning for gold in rivers, to as complex as development of underground workings and small-scale processing plants. . Miners use a variety of methods to locate minerals, including historical knowledge, the observation of other minerals or rocks, or technology such as mineral detectors and audio-based reflection seismology surve
Automated mining involves the removal of human labor from the mining process. [1] The mining industry is in the transition towards automation . It can still require a large amount of human capital , particularly in the developing world where labor costs are low so there is less incentive to increase efficiency.
