After a long period of extensive mining, the amount of domestic minerals has gradually decreased. Outdated mining methods lead to a substantial increase in costs, while leaving many mine tailings. The insufficient utilization of tailings has formed many obstacles to the sustainable development of the industry.

Mine tailings (MTs) are pulverized rock and mineral fractions that are abandoned after the targeted and gangue fractions have been separated [4]. The extensive utilization of primary mineral resources has led to the depletion of high-grade deposits and a shift toward lower-grade deposits.

To be shortly saying, tailings are ground up rock minus the gold. The placer or rocks mined from underground which contains gold is called ore. The gold mining process involves crushing the ore into sand and dust to liberate and recover the gold. What's leftover is called tailings. Overall, there is approximately 95% of the …
