Industrial Grade Crude Salt Raw Material for Water Treatment and Chemical Production

Crude Salt is natural granular salt mainly sourced from sea salt field solar crystallization or underground rock salt primary mining without deep refining, dominated by sodium chloride as core component with natural trace impurities of magnesium chloride, calcium chloride, calcium sulfate and minor sedimentary insoluble substances. The product appears as irregular off-white to yellowish coarse crystal granule with partial fine powder mixed, featuring easy deliquescence in humid air and excellent water solubility. Our crude salt adopts mature natural sun-craft or open-pit mining process, stable sodium chloride content and controllable impurity range, without extra chemical additive during production. As low-cost basic bulk inorganic raw material, it is widely applied in chlor-alkali chemical industry, industrial water softening, road snow melting, aquaculture breeding and leather processing fields.

Applications
**Chlor-Alkali Chemical Raw Material (Largest Consumption Field)**: Fundamental feedstock for electrolytic production of caustic soda, soda ash, liquid chlorine and hydrochloric acid. After dissolving into saturated brine and simple pre-treatment removal of heavy impurities, crude salt enters electrolysis workshop to realize core basic chemical raw material manufacturing, occupying the biggest demand of crude salt consumption in chemical industry.
**Industrial Water Treatment & Water Softening**: Economical regenerant for ion exchange resin in boiler and circulating water softening system. Salt brine from crude salt soaking can restore saturated exchange capacity of sodium-type resin, effectively remove calcium and magnesium hard ions in raw water to prevent pipeline and heat exchanger scaling, greatly cutting operating cost compared with refined salt for large-scale water softening station.
**Road Deicing & Snow Melting Agent for Cold Regions**: Core raw material of environment-friendly road snowmelt product. Crude salt dissolves quickly after spreading on icy pavement to lower water freezing point, accelerate ice and snow melting in highway, urban road and parking lot in winter, widely used in northern low-temperature areas for traffic anti-freeze maintenance.
**Aquaculture & Seawater Hatchery Preparation**: Used for artificial seawater blending in marine fish, shrimp and crab breeding ponds and seedling hatching pools. It adjusts water salinity to simulate natural seawater growing environment for aquatic products, stabilize pond osmotic pressure and improve survival rate of seafood seedlings, commonly used in coastal freshwater transformation breeding projects.
**Leather Tanning & Food Pickling Auxiliary**: Applied as pickling and preservative auxiliary in raw hide soaking and leather tanning processing, restrain harmful microbial reproduction on animal skin surface and improve leather texture stability; small portion of qualified crude salt can be used for preliminary crude pickling of preserved vegetables before fine processing.

Product Advantages
✅ Low cost with high sodium chloride effective content, obvious economic advantage instead of refined salt for industrial bulk usage to reduce customer raw material expenditure.
✅ Natural multi-size coarse crystal form, good permeability and dissolution uniformity, not easy to block feeding pipeline during automatic brine preparation.
✅ Multiple grade options available according to impurity content to match different industry requirements for chemical electrolysis, water softening and aquaculture separately.
✅ Sufficient long-term stock from salt field direct supply, no intermediate markup, flexible delivery for small pallet order and full-container bulk shipment.
✅ Relevant factory inspection certificate provided for domestic trade and export customs clearance.

Packaging & Storage
Standard 50kg inner PE film lined woven bag; bulk loose loading available for large tonnage truck and vessel shipment. Store crude salt in dry, ventilated open shed or indoor warehouse, keep packages intact to avoid long-term rain soaking leading to severe deliquescence and agglomeration. Stack away from strong acid chemical goods to prevent chemical reaction and product deterioration. Shelf life: 18 months under dry storage condition.

Safety Information
Ordinary natural inorganic salt product, non-toxic, non-flammable and non-dangerous goods for all land and sea transportation. Long-time skin contact with high-concentration brine may cause slight skin dryness; wear simple dustproof gloves during loading and unpacking. Flush skin with clean water timely if large amount of crude salt powder stays on body surface.
