The most common halite is known as common salt (NaCl). It is found as a solid in the subsurface and as dissolved material in water (lakes and oceans). A subsurface deposit of the salt is exploited by drilling and water injection to make an underground brine solution. Later the brine solution is pumped out and stored for crystallization. An important aspect of subsurface halite deposits is that the geological forces push them upward to form an arched structure known as a ‘salt dome’. Salt domes are significant both for mining and underground petroleum systems. A major portion of reservoir formation water contains halite minerals. The composition of reservoir water depends on reservoir environment.
Simple Salts and Metal Oxides/Hydroxides/Oxyhydroxides

Our iconic examples of spectator ions in aqueous solution are Na+ and Cl−. NaCl(s) (halite) is then an iconic example of a simple mineral salt. Ks0 values for some other materials that can dissolve as simple salts (under some conditions) are given in Table 11.2. In problems involving dissolution of NaCl(s) in water, the ions in the solid are simply transferred to the dissolved phase, hydrated (i.e., solvated) by water molecules, then henceforth behave as spectator ions. For saturation equilibrium with halite, the total amount of sodium in solution is governed only by Eq.(11.3), which tells the whole story for the dissolution of NaCl(s).

About half of all halite is used to deice roads to make winter driving safer. Chemical manufacturers also use a lot of halite to make thousands of products, including plastic, paper, glass, polyester, rubber, household bleach, soaps, detergents, and dyes. Additionally, the pharmaceutical industry uses halite to make infusions, medicines, and salines. And a few percent of mined halite is used directly by the food production industry, because halite is an important spice and a preservative. Halite also helps people absorb and transport nutrients, maintain blood pressure, maintain the right balance of fluid, transmit nerve signals, and contract and relax muscles.

Sodium chloride, or salt, is an ionic compound with the chemical formula NaCl, which represents the combination of sodium and chloride ions [8]. The basic structure is known as the halite or rock-salt crystal structure, and it can be present in a variety of other compounds. It can be interpreted as two interpenetrating face-centred cubic (fcc) lattices or as a face-centred cubic (fcc) lattice with a two-atom basis. It has wide bandgap energy that is about 8.5 eV [9]. NaCl is naturally crystallized from lakes, seawater mines as solid rock and also as saline groundwater. While impurities can affect the color spectrum of halite, defects within the crystal lattice are caused by the deep blue and violet colors, and bacteria from various algae cause the pink and peach colors of many dry lake halite specimens [10].

The saline mineral halite consists essentially of sodium chloride (NaCl). It is the most commonly mineral found in the composition of sedimentary evaporite rocks (Silva, Schreiber, and Santos 2000). This type of rock, formed from the evaporation of brines, has an important economic significance in sedimentary basins, since they are almost perfect seals for the accumulation of hydrocarbons, strongly conditioning the migration and accumulation of fluids (Schreiber and Tabakh 2000; Warren 2006; Falcão 2009).
