Abstract. Excessive exploitation of rare earth mines produced a great deal of mine tailings which needs proper treatment. High concentration of the total rare earth elements REEs 685.8 - 48.7 mgkg still existed in the mine tailings, which was more than 3 times as much as the average background concentration of China.

Brine mining is by far the most common method of lithium recovery used today. But what is it, and how is brine mining used for lithium recovery. In this article, well look at how and why brine mining relates to lithium production and explore how the principles of brine mining are leveraged to develop new lithium extraction technologies capable of isolating the metal from alternative sources.

From the 1960s to the 1980s, the United States was the leader in global rare earth production. Since then, China has become the world leader in rare earth mining and processing, in part due to lower labor costs, and less burdensome environmental and safety standards. Beginning in 1990 and beyond, supplies of rare earth elements became an issue as the Chinese government tightened its control ...
