Zinc Carbonate is a water insoluble Zinc source that can easily be converted to other Zinc compounds, such as the oxide by heating (calcination). Carbonate compounds also give off carbon dioxide when treated with dilute acids.
Zinc Carbonate Basic (Zinc Hydroxide Carbonate)is a water insoluble Zinc source that can easily be converted to other Zinc compounds, such as the oxide by heating (calcination). Carbonate compounds also give off carbon dioxide when treated with dilute acids. Zinc Carbonate is generally immediately available in most volumes.
synthetic basic zinc carbonates showed that although composition may vary considerably, a particular group of compounds retain the afore- mentioned similarity to the hydrozincite r-ray powder pattern and the group could be crystallographically related to this mineral.

Zinc carbonate (ZnCO3), normally referred to as smithsonite, is an ore that contains the metal zinc. It was named after the English scientist James Smithson (who dedicated his fortune to create the Smithsonian museum in Washington, D.C.). The mineral has a number of uses in health care, metallurgy, electronics, and construction.

Basic zinc carbonate is normally used as an H2S scavenger in water-based systems. If used as pretreatment, in anticipation of H2S gas, no more than 5 lb/bbl (14.27 kg/m3) should be added to the system.
Most of the time the oxidation number of zinc is +2. Charge of Carbonate (CO3) is -2. Then the formula for zinc carbonate is: ZnCO3 Zinc(II)Carbonate
The fine particle-size-distribution of zinc carbonate results in a maximum amount of surface area for fast, efficient sulfide scavenging and is effective in water-base and oil- or synthetic-base fluids.
Zinc is a strong reducing agent with a standard redox potential of −0.76 V. Pure zinc tarnishes rapidly in air, rapidly forming a passive layer. The composition of this layer can be complex, but one constituent is probably basic zinc carbonate, Zn 5 (OH) 6 CO 3. The reaction of zinc with water is slowed by this passive layer.

Smithsonite, or zinc spar, is zinc carbonate (Zn C O 3), a mineral ore of zinc. Historically, smithsonite was identified with hemimorphite before it was realised that they were two distinct minerals. The two minerals are very similar in appearance and the term calamine has been used for both, leading to some confusion.
The basic zinc carbonate is synthesized from zinc sulfate and pure alkali or ammonium carbonate. Its chemical properties determine that it has the functions of accelerating vulcanization, removing hydrogen sulfide and sterilizing in different fields of use.
