What salt is Dingyuan Salt Mine?

Dingyuan Salt Mine is the only salt-making enterprise in Anhui Province, which was founded in 1987. Since 1990 was put into production, it has developed rapidly. It ranks 8th among 100 largest salt mining enterprises in China, 55th among the top 100 enterprises in Anhui Province, 14 among the top 100 enterprises in light industry in Anhui Province, and first among the non-metallic mining and dressing industries in Anhui Province. It is a national designated production enterprise of iodized salt.

At present, it has formed a design capacity of 330,000 tons, and the actual capacity can reach 400,000-500,000 tons. There are nearly 2400 employees and 240 engineers and technicians.

It mainly produces nearly 30 varieties of refined salt, nutrition and health care salt, daily salt, industrial salt, animal husbandry salt and breeding salt. Ore body area 14.4 square kilometers, ore body thickness14.18-198.4 meters, salt reserves1750 million tons, including sodium chloride reserves1240 million tons, which was rated as "rich in resources" by experts.
