| Abstract: | By adopting the method of precipitation and neutralization by limestone and absorption by flyash, better results can be achieved in disposal of the acid wastewater in the mine. The process goes like this: first, use limestone to neutralize the pH value to 4.5;then use lime to make it to neutral state and absorb it with flyash, whose appropriate amount is 10 g/L. ; |
