1. Introduction. The mechanical behavior of anhydrite in salt rocks plays an important role due to the high competence (Ramberg, 1955) of anhydrite layers with respect to halite-dominated rock salt, which may result in fractures and open pore space to store and transmit gas and saline solutions.The behavior of anhydrite rocks is particularly …Web

Winsford Mine is stratigraphically located at the base of the Northwich Halite Formation, which contains 92% NaCl, and the extraction is made by room and pillar mining (Norton et al. 2005). Within the salt mine, two different economically workable levels of rock salt have been differentiated on the halite purity, namely Zone B and Zone F. Zone ...Web

Put simply, salt lowers the temperature at which liquid water turns into ice, a concept known as freezing point depression. People have long known that salting roads helps keep them free of ice, but what hasn't been well understood is how the millions of tons of salt spread on U.S roads every year impact the environment.Web

Gardner also explained the different ways of mining the two types of salt.

Economic impacts of halite. Halite has played a significant purpose in the development of societies. Most people in developed countries think that a halite has few uses, but in the real sense, it has many functions (Zambito and Benison 588). The mineral is currently being used in the process of melting ice on roads during winter seasons.Web
