Salt seems to be found under lakes. The larger the lake the better your chance. This doubles in deserts; although in a desert you have a chance to find Halite on the surface either in the form of dried lake beds or in salt pillars of any rock surface jutting out of the sand layer. So if you aren't having luck with deserts.
Acid mine drainage (AMD) is produced by the chemical reaction of sulfide ore and associated minerals with air and water. This reaction (as shown below) illustrates how sulfuric acid (H 2 SO 4 ) and iron sulfate (FeSO 4 ) are produced when the iron sulfide mineral pyrite (FeS 2 ) reacts with water: FeS 2 + H 2 O + 3.5O 2 = H 2 SO 4 + FeSO 4.

halite is the most soluble common mineral, 360 g l −1 at 25 °C ( Langer and Offermann, 1982 ), which is two orders of magnitude higher than gypsum, and three orders of magnitude larger than limestone; •. in contrast to carbonates, salt solubility does not depend on dissolved gases or acidity; •.
2.168. Crystal System: Isometric. Member of: Halite Group. Name: From the Greek άλς, sea, for halites, later modified by J.D. Dana to halite. Natural sodium chloride (also named rocksalt; water-soluble). Occurs both as evaporite deposits in saline lakes and watercourses, or as bedded sedimentary deposits, or as salt domes.
Importance of Minerals. Mineral resources are essential to our modern industrial society and they are used everywhere.
