Notes:
The effects of carbon dioxide-enriched air on the rate of zinc extraction during the microbiological leaching of a, high-grade zinc sulfide concentrate by Thiobacillns ferrooxidans have been studied. Under normal air-aeration conditions, the leach rate is limited initially by the availability of solid substrate surface area per unit volume of leach liquor, then by availability of carbon dioxide. If carbon dioxide-enriched air is supplied, along with excess substrate, the zinc extraction rate increases as the carbon dioxide content increases until some other, as yet unknown, factor becomes limiting.
