Zinc carbonate: Overview

Zinc carbonate is a chemical compound with the formula ZnCO3. It is often referred to as smithsonite, calamine, or zinc spar. Carbonate zinc is alkaline in nature and readily soluble in acidic solutions. The zinc carbonate basic solution gives off carbon dioxide when treated with dilute acids. The general properties of zinc carbonate are listed below.

Zinc carbonate is also referred to as smithsonite; an ore from which the zinc metal is extracted; the name comes after the English chemist and mineralogist, James Smithson, who created the Smithsonian museum in Washington, D.C. Earlier in those days, miners faced difficulty in extracting zinc from the ore calamine. They found out that certain variety of calamine produced zinc, while the others din’t. Later it was found out that the calamine ore consisted of two substances namely zinc carbonate (smithsonite) and zinc silicate (hemimorphite). Zinc carbonate is a good source of zinc, while zinc silicate is a poor source. This discovery marks an important milestone in the history of mineralogy and combined chemistry with mineralogy, which were two separate discipline of science until 19th century.

Uses of zinc carbonate

  • The most important use of zinc carbonate is zinc metal. Zinc carbonate is the ore from which zinc metal is extracted.
  • It has an ornamental use; when polished with gemstone, it gives a bluish-green color and displays a beautiful luster.
  • Zinc is obtained from zinc chloride, which is used in food and nutrients to support the vital functioning of important enzymes.
  • Zinc carbonate is used on materials, pigments for painting, and agricultural equipment, to protect them from dilapidation.
  • It is dusted over inflamed surfaces as an astringent and absorbent.
  • It is used in ointments and is often referred to as calamine.
  • Zinc carbonate is used in the zinc anodes of the batteries.

Zinc carbonate toxicity

Zinc carbonate is toxic and affect your breath, skin, eyes, and throat; elevated exposure is found to affect the liver too. Zinc intoxication occurs mainly by inhaling the zinc fumes or particles, and ingestion.

Potential health risks

Eye: The contact of zinc chloride fumes, solution, or powder with the eyes causes irritation.

Skin: Skin irritation occurs when zinc chloride comes in contact with the skin.

Ingestion: Ingestion of zinc chloride causes the irritation of the gastrointestinal tract, followed by nausea, vomiting, and diarrhea.

Inhalation: Inhalation of the zinc chloride fumes or particles leads to the irritation of the respiratory tract.

Chronic effect: No information on the chronic effect of zinc chloride has been recorded yet.

First aid measures

When you come in contact with zinc chloride and notice the symptoms of irritation in the affected area, nausea, vomiting, or diarrhea, these first aid measures should be carried out immediately and given medical help.

Eyes: In case of the contact of zinc chloride with eyes, flush the eyes with plenty of cold water at least for 15 minutes with occasional lifting of the upper and lower eyelids. Get medical help immediately.

Skin: When zinc chloride comes in contact with the skin, cut of the cloth in the affected area, flush with it with plenty of cold water, and wash it with soap. If irritation still persists, get medical help without any delay.

Ingestion: In the event of ingestion of zinc chloride, wash the mouth with water using clean hands. Give the person two to four cups of milk or water to dilute the chemical and reduce its effect. Milk/water should be given only to an alert and conscious person; if the person is unconscious, do not offer him anything by mouth and take him/her for medical assistance without wasting any further time.

Inhalation: In case you inhale the fumes of zinc chloride, immediately expose yourselves to fresh air. If the person is unable to breath, give artificial respiration. In case breathing gets difficult, give oxygen, and get medical assistance immediately.

Zinc carbonate: Handling and storage

Zinc carbonate is a toxic chemical compound which can show up affects such as irritation, nausea, vomiting, and diarrhea. Hence, it is important to handle the chemical with care. After handling it each time, make sure to wash your hands thoroughly to avoid any further contamination. Remove contaminated clothes and wash them before reuse. When dealing with the chemical, make sure to check the place for adequate ventilation. Also, try to avoid ingestion, inhalation, or any kind of contact with eyes and skin.

Personal Protective Equipment you should use while handling zinc carbonate.

Eyes: Always wear appropriate protective eyeglasses or chemical safety goggles.

Skin: Make sure to wear appropriate protective gloves to prevent any skin exposure.

Clothing: Wear a lab apron and appropriate protective clothing to prevent skin exposure.

When you are storing zinc carbonate, make sure to store it in tightly closed containers, in a cool, dry place away from sunlight.

Zinc Carbonate: Global Market

The increasing use of zinc carbonate in the cosmetic, chemical fertilizer, and rubber industry had led to steady growth of the chemical from 2017 and the trend will continue to 2024 and beyond. The global cosmetic industry alone valued at about $330 billion in 2016. Furthermore, the growing market of chemical fertilizers in the Asia Pacific region has been a major activator for the growing demand for zinc carbonate in this region.
