fossil salt - Physico-chemical Properties
| Physical and Chemical Properties | Nature rock salt is one of the main minerals of sodium salt ore. Equiaxed crystal system, the crystal is cubic, usually granular or block aggregate. Pure colorless transparent or white, often containing mechanical mixture of rock salt in various colors, such as gray, yellow, red, blue or black Brown. Glass gloss, weathered surface is oil gloss. Hardness 2~2.5, density 2.16g/cm3. Soluble in water, salty taste; Low thermal conductivity; Non-conductive, friction light; Strong hygroscopicity, easy deliquescence. Halite is one of the most widely distributed salt minerals, mainly in the marine carbonate series, clastic series sedimentary deposits and dry salt lake sediments in arid climate inland basin, and gypsum, anhydrite, the symbiosis of polyhalite, carnallite, potassium salt, calcium sulfate, etc. |
fossil salt - Introduction
Mineral salt refers to the soluble salts contained in natural minerals, including edible salt, rock salt, sea salt and so on. The properties of mineral salts are generally as follows:
1. Solubility: mineral salt has good solubility in water and can be quickly dissolved into salt water.
2. Crystallinity: Under appropriate temperature conditions, mineral salts can be crystallized to form crystals.
3. density: mineral salt density is generally higher.
mineral salt has a wide range of uses, mainly including the following aspects:
1. seasoning food: edible salt is a kind of mineral salt, which is an indispensable condiment in human daily life.
2. Food processing: mineral salt plays an important role in food processing, which can improve the taste and freshness of food.
3. chemical industry: mineral salt used in the preparation of chemicals, glass, detergent, etc.
4. metallurgical industry: mineral salt is used as auxiliary agent for smelting ore and metal in metallurgical industry.
5. pharmaceutical industry: mineral salts are used in the pharmaceutical industry to prepare drugs, hemostatic agents, etc.
The preparation method of mineral salt is varied, mainly including the following:
1. vacuum evaporation method: the natural mineral is dissolved in water, and then through heating and vacuum treatment, the solution is gradually evaporated and concentrated, until the mineral salt crystal is obtained.
2. Precipitation method: React a specific salt solution with other chemical reagents to produce precipitation, and then filter and dry to obtain mineral salt.
3. deposit extraction method: the mineral salt in the ore is separated by mining and physical treatment.
Some safety information to be aware of when using and handling mineral salts:
1. avoid direct contact: some mineral salts contain irritating substances, avoid direct contact with skin, eyes and respiratory tract.
2. storage safety: mineral salt should be stored in a dry, well-ventilated place, away from fire and flammable materials.
3. Use the right amount: the intake of mineral salt should be appropriate, excessive intake may have a negative impact on health.
4. chemical reaction: the solution of mineral salt should be used in conjunction with other chemical substances to avoid dangerous chemical reactions.
