Individual prospectors typically dig small mines or pan for gold, or use small scale sluice boxes. Companies might do that as well, but they also engage in larger operations like strip mining.

The cars in a common mine train are usually called "hoppers".

No, the m50 mask is not the most effective in confined spaces where there is not enough oxygen in the air to breathe to support life.

Mining can significantly impact local communities, both positively and negatively. On one hand, it can create jobs and stimulate economic growth, providing vital income for families. However, it often leads to environmental degradation, including pollution and habitat destruction, which can harm the health and livelihoods of nearby residents. Additionally, mining activities can disrupt social structures and lead to conflicts over land and resources.

The Carajás mines in Brazil, primarily known for iron ore extraction, employ thousands of workers. As of recent reports, around 10,000 people work directly in the mining operations, with additional indirect jobs related to logistics, maintenance, and support services. The exact number can fluctuate due to operational changes and economic conditions.

Depends on what is being quarried. If the product is aggregate (gravel), you would use a rock drill, bulk explosives loading trucks, bulldozers, front end loaders, transport trucks, a jaw (primary) crusher, cone mill (secondary) crusher, magnetic separators (to pull out iron and steel scrap) sizing machinery (such as a trommel) and conveyor belts.

Basically, anything that is not grown has to be dug out of the earth. That includes all metals, all minerals, oil and gas deposits. Odds are the power you are using in your computer right now came from mining- coal, oil, gas or uranium. Your computer contains 37 different elements that were obtained by mining. The wires that bring electrical power to your home are metals- from mining. It would be hard to find a room in your home that does not contain something that came from mining.
