DESCRIPTION


DESCRIPTION


Zinc Carbonate is a colourless or white solid that is found in nature forming the Smithsonite mineral, in which it can be alone or with other elements such as cobalt or copper, which give it violet or green colour respectively. ZnCO3 is almost insoluble in water, but it dissolves easily in dilute acids since the carbonate ion in an acidic medium forms carbonic acid (H2CO3), which is then converted into CO2 gas and water. It is used as an antiseptic in animal wounds and is sometimes supplied in the diet to avoid diseases caused by zinc deficiency.


APPLICATION


APPLICATION


Zinc Carbonate has a lot of applications. The main ones are listed below:


In Veterinary Applications

It serves as an astringent, antiseptic, and topical wound protector in animals.

It also helps prevent diseases caused by zinc deficiency, which is why it is used as a supplement in the diet of some animals, provided that the amounts administered are within the standards established by health organizations.

Zinc carbonate is sometimes administered as a micronutrient to prevent disease in animals.


In Medical Treatments

This compound allows for obtaining some pharmaceutical products. It is applied to inflamed skin in the form of a powder or lotion.


As a Flame Retardant

It is used as a fireproof filler for rubbers and plastics that are exposed to high temperatures.

It protects textile fibres from fire. In the case of cotton textiles, it is applied to the fabric along with some alkali. This directly attacks the primary hydroxyl groups (–CH2OH) of the cellulose and converts them into sodium cellulose (–CH2ONa).

The breakdown of cellulose bonds by the alkali favours a greater penetrability of the chains of the compact cellulosic structure, which is why more ZnCO3 manages to enter the amorphous zone of this, and its dispersion is facilitated.

Some cotton fabrics may contain ZnCO3 in their fibres to make them fire-resistant. As a result, the amount of flammable gas that could be produced by fire is reduced.


To Separate Dangerous Minerals from Arsenic

Methods of separating arsenic minerals from sulfide rocks (such as galena, chalcopyrite, and pyrite) have been tested using ZnCO3. The mineral-rich in arsenic must be separated from the others because this element is a very toxic and poisonous pollutant for living beings.

To achieve this, the mixture of the ground rocks is treated with a solution of zinc sulfate and sodium carbonate at a pH of 7.5-9.0 and a xanthate compound.

The effectiveness of the formula is attributed to the formation of small ZnCO3 particles on the surface of the arsenopyrite, making it hydrophilic (related to water), so it cannot adhere to air bubbles and cannot float, precipitating and separating of the other minerals.


In Dental Treatments

Certain toothpaste based on zinc carbonate and hydroxyapatite nanocrystals are applied regularly to the denture. It reduces hypersensitivity more effectively than those based on fluorine.

ZnCO3 and hydroxyapatite nanocrystals have a size, shape, chemical composition and crystallinity similar to that of dentin so that the dentinal tubules can be closed with the application of these materials.

ZnCO3 -hydroxyapatite nanoparticles have been successfully tested to decrease sensitivity in whitened teeth. This type of toothpaste is useful after teeth whitening processes.


In The Recovery of Zinc from Residual Effluents

Synthetic waters rich in zinc ions discarded by electroplating processes can be treated by fluidized bed technology using sodium carbonate to precipitate ZnCO3.

By precipitating the Zn2+ in the form of the carbonate, its concentration decreases, the solid obtained is filtered, and the waters can be disposed of safely. The precipitated ZnCO3is of high purity.
