Study on Neutralization Treatment of Tantalum-niobium Hydrometallurgical Extraction Waste water
A new technology was used to treat mineral extraction wastewater,which turned the wastewater into products,and reducd the pressure of wastewater treatment.The process flow of neutralization treatment of mine extraction wastewater was introduced.Calcium hydroxide was used as raw material,and calcium salts such as calcium sulfate were added into mine extraction wastewater and stirred to produce calcium salts.The influence of various factors on the shape and pH of calcium salt was analyzed,so as to determine the more optimized process conditions.
