So, if you apply heat, salt melts before sand. You can use the melting point difference to separate a mixture of sand and salt by heating the mixture above 801°C, but below 1710°C. Pour the molten salt off, leaving the sand. While it's possible to separate the components of the mixture using melting point, it's not very practical.

Introduction. Sand and gravel are used extensively in construction. In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b). Thus, the world's use of aggregates for concrete can be estimated at 25.9 billion to 29.6 billion tonnes a year for 2012 alone.

Oil spills are a vicious consequence, not always caused by the process of extraction. In fact, the National Research Council estimates the origin as follows: – 46% naturally seeping into the Ocean. – 37% discharged from operational processes in sea, and land-based sources. – 12% accidental spills from ships, and. – 3% extraction processes.

A harvester comes along to scoop up the salt and transfers it to dump trucks, which then carry the salt to the washing facility. The salt is rinsed first in a brine solution to wash out calcium and other impurities, and then in actual Bay water to dissolve the magnesium chloride. What you're left with is 99.8% pure sodium chloride sea salt.
