摘要
The present work is designed to simulate the dissolution of sulphate rock under various conditions of different bacterial cell numbers, temperatures and reaction times both in water-rock and water-rock-bacteria systems by laboratory experiment. The results show that chemical dissolution of sulphate rock is dominated in water-rock system, while bacterial sulphate reduction process and the dissolution of sulphate rock driven by bacterial sulphate reduction are dominated in water-rock-bacteria system.
