(a) The as-received, crude distillation column bottom pump consists of halite
[NaCl]; (b) the sludge, which shows the hydrocarbon peak.
In the study area, the main cations are [Na.sup.+], [Ca.sup.2+], and [Mg.sup.2+] and the main anions are HC[O.sup.-.sub.3], S[O.sub.4.sup.2-], and [Cl.sup.-]; thus gypsum, anhydrite, calcite, dolomite, aragonite, and halite
are chosen to be the mineral facies.
Based on the geochemical results using Phreeqc, the water samples from San Jose and Linabo were undersaturated with respect to anhydrite, gypsum, and halite
. Table 3 presents the saturation indices of the minerals phases.
Downstream soils (floodplain and low terrace) contain high amounts of halite
. Feldspars, mainly albite (NaAl[Si.sub.3][O.sub.8]), are identified only in the floodplain and low terrace profiles.
Potential salinization sources are diverse, including natural saline groundwater, halite
dissolution, presence of paleo-brackish water, seawater intrusion, oil and gas-field brine, domestic, agricultural and industrial effluents, and road salts.
Theoretically, if [Na.sup.+] and [C.sup.-] are derived solely from the dissolution of halite
, the ratio of [Na.sup.+] and [Cl.sup.-] in mmol/L should be equal to 1 (Li et al.
(1997) studied the halite
dissolution kinetics considering the model of the mass coefficient according to each ion.
is a dominant source of [Na.sup.+] and [Cl.sup.-] in the groundwater; the molar ratio varies spatially as a result of the cation exchange .
Otherwise known as the mineral halite
, table salt is composed of crystals that are tiny cubes you can see with your eyes or, even better, with a magnifying glass.
-- Deposits of sabkha: Most of these sediments south of Lake Bardawil an area of 229.9 [km.sup.2] and consists of sand, clay and silt and contain different proportions of sand, gypsum and halite
' an average thickness of up to 10 meters.
I also came across Himalayan Pink Salt or halite
in Legaspi Market in Makati being sold by health food advocate, Arthur Tanco, together with his wheat grass, yogurt products and herbs.
Once about 80-90% halite
precipitation has occurred, the enriched potash brine will be transferred from the three large tanks to two smaller tanks for final crystallisation of mixed potash salts (including schoenite).
