What ores are considered to be non-renewable resources?

ChosenEvery ore deposit is a non-renewable resource. Having said that it is the job of technology to make the price of a metal competitive, affordable. Initially when not much in demand the technology of mining it, extraction needs to pick up bringing its price down. Later demand may push up its price and the extra expenditure for adding to its supply may become unaffordable, making it appear non-renewable. A stage will come when a particular metal or more metals may have to be recycled as the quantum of it is fixed in nature.
Water as consumable is no exception. So far as Sun is renewing it by sucking it from oceans, forming clouds and precipitating it in the form of rains, man

West Virginia, Kentucky, and Pennsylvania are the largest producers of bituminous coal.
Subbituminous coal has a lower heating value than bituminous coal. Subbituminous coal typically contains 35-45% carbon. Most subbituminous coal in the United States is at least 100 million years old. About 46% of the coal produced in the United States is subbituminous.
Wyoming is the leading source of subbituminous coal.
Lignite is the lowest rank of coal with the lowest energy content. Lignite coal deposits tend to be relatively young coal deposits that were not subjected to extreme heat or pressure, containing 25%-35% carbon. Lignite is crumbly and has high moisture content. There are 19 lignite mines in the United States, producing about 7% of U.S. coal.
Most lignite is mined in Texas and North Dakota. Lignite is mainly burned at power plants to generate electricity. back to top

Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. Many U.S. coal beds are very near the ground's surface, and about two-thirds of coal production comes from
