Winsford Mine

Winsford Mine (also known as Meadow Bank Mine) is a halite (rock salt) mine in the town of Winsford, Cheshire, England. The mine produces an average of 1,500,000 tonnes (1,700,000 short tons) of rock salt a year, which is used to grit public roads in the United Kingdom during the winter months. Two other mines also produce rock salt within the United Kingdom, but Winsford has the biggest output of all three and has the largest market share. It is also Britain's oldest working mine.
