How and where is it mined? In smaller bodies of salt water, evaporation will make a vapor that rises. Then the salt in the water will form crystals and fall back into the water. When this happens over and over, a bed of salt is made. Salt is mined in different ways depending on where it is found or even made. For the salt that is found where seas used to be, underground mining can be used. The miners will use normal mining methods like the ones in hard rock mining to do this. Room-and-pillar mining is done. This is where the tunnels are divided into rooms by man-made pillars of salt [like the pillars of coal in a coal mine]. Tunnels are dug, holes drilled, and big blocks of rock salt are taken out just like they do with coal. A good thing about mining rock salt is that there isn't any water or gas in the mines. Electric shovels put the salt into trailers to take it to a crushing machine. In some mines, the crushing and screening are done before it is brought out of the mine. Since salt will dissolve in water, sometimes solution mining is done. Solution mining is where a shaft is dug down into the rock salt. Hot water is forced down into the shaft where it dissolves the salt walls around it. This forms a brine. [To see what a brine looks like, mix about 1/8 cup of salt in 1 cup of warm water. Stir until it is dissolved. You won't be able to see through it. This is a brine.] The brine is pumped to the surface and then the water evaporates from it, leaving the salt. In other places where salt is found, miners will just scrape salt layers off of the bottom of lakes [salt lakes]. A third of the salt in the U.S. comes from hard rock mining, one half from solution mining, and the rest from separating the salt from sea water and dried up lakes. Once it is taken out of the ground, it is separated according to what it will be used for and then crushed and sorted by size. The best salt becomes table salt and is mixed with other minerals to keep it from clumping up. Salt is mined in the United States, China, Germany, India, and Canada. Most of the United States' salt comes from Louisiana, Texas, and New York.

Bauxite is aluminum (Al) ore: Al2O3
Aluminum cannot be extracted from it. Only chemical electrolysis leads to aluminum metal.
Halite is more commonly known as rock salt. This is the solid mineral form of sodium chloride, and thus can be used to extract sodium.
Halite, more commonly known as rock salt, can be made to yield sodium metal by electrolysis.
'Ore' refers specifically to a mineral or group of minerals utilized for the purpose of extracting metals. Halite is a mineral with the composition NaCl, and is non-metallic.
No. Magma is not an ore.
Ore is a rock that contains minerals , an example of an ore can be almost anything!
Ore is rock from which a metal or valuable mineral can be extracted. Iron ore, copper ore are two examples.
Yes! It is rock that is not ore, but surrounds the ore.
Copper ore is called CHALCOPYRITE.
Halite is usually white, but can come in many colors.
Yes Halite is a compound witch means salt.
The ratio of halites to all other compounds in the universe is 0.
Piercement structures. Like salt domes and anticlines.
Uranium ore is not...uranium ore !
This is a product otherwise known as rock salt. The Greek word is 'Hals'. The Latin word is 'Halites'
iron ore iron ore
The name for tin ore is "Tin Ore." There is no other name for tin ore..... Also, you can combine a tin ore to a copper ore to make a bronze bar. :)
It means a mineral deposit that has some metal, precious or no. I.E. gold ore, iron ore, copper ore, zinc ore ETC.
Ore is gold or silver as an example, but lode is a vein of an ore that gives a lot of the ore.
the mining of ore is when you get ore from a rock you mine anywhere in runescape.
