Salt is a very important mineral in humans every day life. Humans use it as a preservative for food, deicing roads and even for seasoning their foods.
Around 300 BC salt was difficult to acquire, which made it very valuable(“Salt Works,” 2014). In some places, this highly valued trade item was a form of currency. Salary is derived from the Latin word “Salarium”. Salarium was a word used to describe payments to Roman soldiers in salt (“Salt in History,” 2010).
Salami is derived from the Italian word “sale”. The original meaning of sale meant all kinds of salted meats(“Salt in History,” 2010). Salad is derived from the Latin word “salata”. Salata meant salted vegetables, as the Romans would season their greens with salt (“Salad,” 2014). Hallstatt derives from the Celtic word “hall” which means salt. The town of Hallstatt, Austria is well known for its production of Salt dating all the way back to 5000 BC. Hallstatt is also home to the oldest known salt mine (“Hallstatt Salt Worlds, 2014).
How we Obtain Salt
Mining for salts is very similar to mining other rocks and minerals. Salt can be buried deep underground. The salt is buried there do to changes of the earth’s tectonic plates over long periods of time. Shafts are made to drill deep into the deposit of the mine where the salt is crushed. Conveyor belts are then used to bring the crushed salt to the surface. The end result of mining for salt is rock salt. Rock salt has many uses but one of the main uses is road salt to de ice roads (“How Salt Works,” 2014). Mechanical evaporation for salts begins by adding water to underground salt deposits. As the water evaporates, you are left with large salt crystals. The crystals are the...
