Research Progress of Acid Mine Drainage Treatment Technology in China

Abstract

Acid mine drainages treatment technology is a hot issue in the mining industry. It summarizes the causes, the reaction mechanism and impact on the environment of acid mine drainage, and introduces the monitoring indicators of acid mine drainage. Further it focuses on the acid mine drainages terminal treatment technologies that including neutralization, sulfide precipitation, microbiological method, constructed wetlands, membrane method and the iron-carbon micro electrolysis, with the analysis of its theories, advantages, disadvantages and practical application. Meanwhile it introduces the major source control technologies, and further proposes the development tendency that is from terminal treatment technology to the combination of source control and terminal treatment technology. And its a focus and hotspot in the research of the acid mine drainage in China's future.

“…AMD is severe in closed and abandoned mines when pumps are shut off, causing water tables to recover [5]. In Asia [6,7], Europe [8], South America [9], North America [10], Africa [11], and Oceania [12], AMD studies have shown that it has detrimental consequences.…”

“…Biological methods include constructed wetland method and microbial method [11]. In the actual treatment process, the cost of physical and chemical treatment of AMD is high, and it is extremely easy to cause secondary pollution [12]. Constructed wetland method covers an large area, and is vulnerable to seasonal climate [8].…”

“…Constructed wetland method covers an large area, and is vulnerable to seasonal climate [8]. As a result of its harmless and economic characteristics, microbial method is currently the most promising and concerned treatment method for AMD treatment [12]. Microbial method uses organic matter as carbon source and energy through sulfate-reducing bacteria (SRB) in anaerobic conditions to reduce SO 4 2-to S 2-.…”
