文摘

Serpentine is partially dehydrated and converted to olivine by intensive dry grinding. Minor water formed by serpentine dehydration changes the dry grinding into kneading. Serpentine reduces the effect of mechanical activation in disorder olivine's structure. 3600 kWh/t energy input can improve the carbonation conversion from 8.7% to 31.7%.
