Product Description
Sea salt is obtained through the evaporation of seawater, with sodium chloride as its main component. However, it retains a variety of natural minerals from seawater, such as magnesium, calcium, and potassium. The production process of sea salt primarily involves natural solar evaporation, where seawater is evaporated in salt pans to crystallize the salt. Depending on its use, sea salt can be divided into edible sea salt and industrial sea salt.The application areas of sea salt are relatively broad, encompassing both edible and industrial uses. Edible sea salt is mainly used for cooking and food preservation, adding a unique flavor to food. Industrial sea salt, on the other hand, is utilized in chemical production, water treatment, bath salts, and other fields.The advantage of sea salt lies in its natural composition and rich minerals, which give it high value in the food and health product sectors. Additionally, the production process of sea salt is relatively environmentally friendly, relying mainly on natural evaporation, thus having a smaller impact on the environment.
Sea Salt Production Process
(1) Seawater Collection:
Seawater, the raw material for large-grain sea salt, is typically collected from shallow beaches or bays in coastal areas. The collected seawater needs to undergo preliminary filtration to remove larger impurities and suspended solids.
(2) Evaporation in Salt Pans:
The collected seawater is introduced into salt pans, which usually consist of multiple evaporation ponds. Under the influence of sunlight and wind, the water in the seawater gradually evaporates, increasing the concentration of salt. To ensure the quality of the salt, the depth of the water in the evaporation ponds needs to be adjusted according to weather conditions.
(3) Crystallization and Collection:
When the salt concentration reaches saturation, salt begins to crystallize. The crystallization process usually takes several weeks or even months to ensure the size and quality of the salt grains. After crystallization is complete, the salt grains are collected from the salt pans either manually or mechanically.(4) Drying and Packaging:
The collected salt grains need to be dried to remove excess moisture. After drying, the salt grains are screened and graded to remove impurities and fine particles. Finally, the salt grains are packaged into products of different specifications, ready for sale.

Application
Sun-dried crude salt, as a natural industrial raw material, has a wide range of applications in the metallurgical industry. Its main component is sodium chloride (NaCl), and it also contains small amounts of impurities such as calcium, magnesium, and sulfate. These components enable sun-dried crude salt to play multiple important roles in the metallurgical process.
The specific applications are as follows:
I. Chlorination Roasting Agent
In the processing of metal ores, sun-dried crude salt is often used as a chlorination roasting agent. Chlorination roasting is a process that converts metal oxides into metal chlorides through chlorination reactions, thereby increasing the extraction rate and purity of metals. For example, when processing copper ores, adding sun-dried crude salt can promote the chlorination reaction of copper, which can then be extracted through subsequent separation and reduction steps.
II. Quenching Agent
In the heat treatment of metals, quenching is a crucial step that rapidly cools heated metals to achieve high strength and hardness. A solution of sun-dried crude salt can be used as a quenching agent. Its high-concentration salt solution provides a rapid and uniform cooling effect while reducing oxidation and decarburization on the metal surface. This helps improve the surface quality and service life of metal parts.
Applications in Printing and Dyeing Process
(1) pH Adjustment
During the printing and dyeing process, many dyes and auxiliaries need to be within a specific pH range to achieve the best results. Sodium chloride in sun-dried crude salt can be used to adjust the pH of the dyeing solution, ensuring the stability and uniformity of the dyeing process. For example, when using reactive dyes for dyeing, sodium chloride helps maintain the acid-base balance of the dye solution, improving the dye uptake rate.
(2) As a Dyeing Assistant
Sodium chloride is often used as a dyeing assistant in the printing and dyeing process. It can increase the solubility and dispersibility of dyes, making it easier for dyes to be evenly distributed on fibers. Additionally, sodium chloride can enhance the binding force between dyes and fibers, improving dyeing fastness. For example, adding an appropriate amount of sodium chloride in the dyeing of cotton fabrics can significantly improve the dyeing effect.
(3) Promoting Dye Reduction
In some reduction dyeing processes, sodium chloride can act as an auxiliary component of the reducing agent. It helps dyes to better combine with fibers in the reduced state, thereby improving the uniformity and depth of dyeing. For example, when using reduction dyes for dyeing cotton fabrics
Applications in Drilling Fluid
(1) Stabilizer
In the petroleum drilling process, the performance of drilling fluid (mud) is crucial for drilling efficiency and wellbore stability. Sun-dried crude salt can serve as a stabilizer for drilling fluid, helping to maintain the rheological and filtration properties of the mud. Adding an appropriate amount of sun-dried crude salt can:
• Protect the integrity of salt rock cores: During the drilling of salt rock layers, sun-dried crude salt can prevent the dissolution and collapse of salt rock layers, ensuring the smooth progress of drilling.
• Adjust the density of the mud: By increasing the density of the mud, sun-dried crude salt can better balance the formation pressure, preventing blowouts and wellbore leakage.
(2) Weighting Agent
Sun-dried crude salt can also act as a weighting agent for drilling fluid, increasing the density of the mud. High-density mud is particularly important in deep wells and high-pressure wells, as it can effectively prevent the invasion of formation fluids and maintain wellbore stability.
