Salt occurs in nature as the mineral halite and is mined by three primary methods: underground mining, which produces rock salt, solar evaporation, and vacuum evaporation. The Salt Institute's web site explains each process as follows: Rock salt: Rock salt is mined from underground deposits by drilling and blasting. Deposits are reached ...

Halite primarily forms from the evaporation of seawater. Roughly 90% of the original volume of seawater must be evaporated before the concentration of the remaining brine is high enough to precipitate halite. So, significant halite production is usually restricted to arid environments in which the influx of seawater is relatively low compared ...

Potash Refining. The Sylvinite ores mined in conventional mines contain Sylvite (20 to 30% K2O), Halite, sometimes Carnallite and 1 to 5% insol. Liberation, in some cases, is substantial at 1 cm (3/8 inch), and virtually complete in all cases at 14 mesh. The separation processes include dissolution of the Carnallite, and removal of the insols ...

During normal summer conditions, 90% of the halite present in the brine is precipitated with little contamination by other salts. The salt crust (97–99% NaCl) was pre- cipitated by the solar evaporation on the lake basin during May and September. The annual halite sur- face reserve of the Salt Lake is approximately 211.2×10 6 ton.

In the dry steam-driven evaporation stage in the processing plant, moisture is removed, and the recovered brine is brought to saturation point. But halite and sylvite have different temperature responses. Halite is crystallised first by evaporating the recovered brine, and then potash is recovered by cooling the remaining hot, saturated solution.

How is halite mined? Geology. Underground Halite deposits are often mined by drilling wells into the salt layer, and bringing in hot water which quickly dissolves the salt into a brine. The brine is saturated with dissolved salt and is then pumped out. The brine evaporates and the remainder salt crystallizes and is harvested.
