Mining
Mining for coal is something that is widely known, but did you know that diamonds, uranium, copper, and other non-renewable natural resources are also mined? There are two types of mining; surface and subsurface. Questions about the methods and types of mining, what ores are mined, and related questions should be asked in this category.

Why is hardness a valuable property of some minerals?
Hardness is valuable because it helps in mineral identification by determining resistance to scratching. Minerals with higher hardness values can scratch minerals with lower hardness values, aiding in their classification. Hardness also indicates the strength and durability of a mineral, making it useful for industrial and practical applications.

What are Colorado's scarce natural resources?
Colorado continues to list oil shale deposits as a potential 1 trillion barrels of oil that remains unproven economically using current technology. As the world's cost of oil increases and science improves, it may still become the oil production center of the world. It has ample coal deposits, gold is still mined, natural gas productiion contiinues and hydroelectric power potential has not been fully exploited. It has geo thermal and wind power potential and is a major corn producer. Water availability continues to be the number one political problem in the state.
What mining skills did Edward Hargraves learn in the California gold fields?
Edward Hargraves learnt to "read" the countryside from his experiences in California. He brought back to Australia knowledge of gold-bearing countryside, being able to recognise prospective gold country, which enabled him to find the first official, payable gold.
Hargraves also brought with him knowledge of "cradling". Cradling involved a wooden box loosely resembling a cradle. The cradle was used for sifting through larger amounts of sediment to find gold, and was popular from the early times of the goldrushes. It required at least two men to work. The cradle had a grate and a sieve. The dirt and sediment to be sifted through was emptied onto the grate in the cradle. The cradle was rocked quickly back and forth (in the action of a cradle) while water was poured over the sediment to help work it through. The grate stopped coarser stones from going through, while the fine material was sifted out the other end. The gold would be left behind for easy collection.
Where is Old Palos mine located?
In western Jefferson County, AL between Porter Road, Flat Top Road, and Union Grove Road. This area has been clear cut and heavily strip mined in the last few years leading to the disappearance of several grave yards and burial sites. The right of way along Porter Road is still posted NoTrespassing, No Hunting,-Palos LLC. and there are numerous high points from which to observe the area thru telescope, or binoculars. I have been told several times that the mine site has a cemetery across from it that the dead from the explosion in the early nineteen hundreds are buried. This area is still sparsely populated and undeveloped, with very few acceptable roads ( Porter Road is in such poor condition it is hard to belive it is a county maintained road ), so plan on going slow, and traveling in a pickup or SUV when searching the area.
