Because its dissolving power incease a bit with an increase in temperature.
Rock salt is separated industrially through a process called solution mining or cavern mining. This involves injecting water into underground salt deposits to dissolve the salt and then pumping the saltwater solution to the surface. The solution is then evaporated to recover the rock salt.

In several ways. They can pump seawater into evaporation troughs. They can drill holes in salt deposits and pump in water, let the water dissolve the salt then pump the brine into evaporation troughs. They can also mine the salt like any other mineral would be.
Here are two of the main categories of mining:Underground Mining - Underground modes of access include drift, slope, and shaft mining, and actual mining methods include longwall and room and pillar mining. Drift mines enter horizontally into the side of a hill and mine the coal within the hill. Slope mines usually begin in a valley bottom, and a tunnel slopes down to the coal to be mined. Shaft mines are the deepest mines; a vertical shaft with an elevator is made from the surface down to the coal.Surface Mining - Surface-mining methods include area, contour, mountaintop removal, and auger mining. Area mines are surface mines that remove shallow coal over a broad area where the land is fairly flat. Huge dragline shovels commonly remove rocks overlying the coal (called overburden).
Open cast mines, coal mines, silver mines, land mines.

The mines where you get gold are usually called "gold mines".
Mines was doing the same thing and the solution was to replace the front U-joint. Its fine now.
There are various types of mines in the world, including open-pit mines, underground mines, placer mines, and drift mines. Each type of mine is designed for different geological conditions and extraction methods.
There are several types of mines near Hemet, CA, including sand and gravel mines, aggregate mines, and clay mines. Additionally, there are historical gold and silver mines in the surrounding area.
There are various types of mines in action today besides gold mines, such as coal mines, copper mines, iron ore mines, and diamond mines. Each type of mine is dedicated to extracting different minerals or resources from the earth.
Mines in which the coal was mined.
