The cold weather in Britain will see the gritters out on the road, but rather than making use of the traditional grit, gritters now spread rock salt. Rock salt itself is now mined in huge amounts, and such mines are located all around the world. Brown in colour, rock salt bears more resemblance to grit than it does to table salt. In Roman times table salt itself was mined, and although modernisation now means machines do the work of manual miners, this just means that more salt is being mined than ever. In Britain the majority of rock salt comes from County Antrimâs Irish Salt Mining and Exploration Company, Teessideâs Cleveland Potash, and Cheshireâs Winsford Rock Salt Mine. These mines go deep underground, and bore into salt deposits formed many millions of years ago.
