Why is rock salt not used for cooking and de-icing alternatives

Industrial rock salt, despite being chemically similar to table salt, is generally not used for cooking due to significant impurity risks. While both are primarily sodium chloride (NaCl), unprocessed rock salt, or halite, contains trace minerals, dirt, and potentially harmful substances that are removed during the refining process for food-grade salt. This makes the industrial version unsuitable and unsafe for human consumption, contrasting sharply with its use for de-icing roads.
