01-01-2012  According to incomplete statistics, for example, China discharges more than 0.5 billion tons tailings every year, and the rate of comprehensive utilization of tailings is less than 7% at present. The output of tailings in a mine depends on the grade of ore beneficiated in mineral processing plant. Generally, high grade of ore generated less tailings.

What is Lithium Extraction and How Does It Work?

Mineral ore deposits are often richer in lithium content than are salar brines, however, they are costly to access since they must be mined from hard rock formations. Due to the added energy consumption, chemicals, and materials involved in extracting lithium from mineral ore, the process can run twice the cost of brine recovery, a factor that has contributed to its smaller market share.

Nickel Ore - an overview ScienceDirect Topics

This and the high cost of working underground explain why underground orebodies must contain higher grades of nickel ore than open-pit orebodies. Ore grade has a direct effect on mine investment costs expressed in US$ per annual tonne of nickel. Consider two identical ore bodies, one containing 1.25% Ni ore and the other containing 2.5% Ni ore.
