Analysis of Heavy Metal Content and Hydrochemical Characteristics in Tungsten Mining Area
Taking a tungsten mining area as the research object,the chemical characteristics of heavy metal content,pore water,and discharged water in the tailings of the mining area were monitored and analyzed.The results showed that the heavy metal element iron(Fe)had the high content and lead(Pb)had the low content in the mining area.Among them,each heavy metal element content is highest at No.1 tailings,the zinc(Zn)element content is high at No.2 tailings,the iron(Fe)element content is high at No.3 tailings.In terms of water quality,the pH value of the accumulated water in the first tailings pit is 7.08,the pH value of the accumulated water in the second tailings pit is 6.73,the pH value of the accumulated water in the third tailings pit is 6.26,and the pH value of the accumulated water in the fourth tailings pit is 4.6.
