The initial treatment of zinc carbonate is usually 1.5 to 3 lb/bbl (3.75 to 8.0 kg/m3), depending on requirements. Subsequent field treatments should be based on approximately 1 lb/bbl (2.85 kg/m3) of zinc carbonate per 800 mg/L of sulfides detected. One hundred kilograms (kg) of zinc carbonate reacts with approximately 25 kg of hydrogen sulfide.

Zinc carbonate. Zinc carbonate, with the chemical formula ZnCO 3, is a white substance.

Zinc bioavailability correlates with solubility in aqueous solution, with zinc sulfate and acetate being highly soluble and easily absorbed, while zinc carbonate and oxide are practically insoluble and have significantly lower bioavailability (Allen, 1998).

Zinc Carbonate (ZnCo3) is a neutral salt that is used as a sulfide scavenger in water base mud. When compared to zinc basic carbonate, Zinc Carbonate is less soluble and is also slow in reacting with sulfide ions. A Garrett Gas Train is used to analyze soluble sulfides in mud filtrates wherein one lb/bbl per 500 milligram per liter sulfide ion ...

Smithsonite, also known as turkey fat or zinc spar, is the mineral form of zinc carbonate (Zn CO 3).Historically, smithsonite was identified with hemimorphite before it was realized that they were two different minerals. The two minerals are very similar in appearance and the term calamine has been used for both, leading to some confusion. The distinct mineral smithsonite was named in 1832 by ...
