Due to the naturally high level of salt purity of the Qattara salt, it is an ideal salt for de-icing. Sigma Mining produces de-icing salt in small grain sizes which produce more effective results when spread on the roads and pavements. Sigma De-Ice Salt is available as free-salt, in jumbo packs, or in 25 kg an 50 kg bags upon request
