New approaches for extracting and recovering metals from mine tailings
When bioleached aerobically at 30 °C, ∼35% of the copper was extracted from CLC tailings during the first two weeks, but after that time copper concentrations decreased alongside those of soluble iron (Fig. 2 a), and the final copper concentration in the leach liquor was equivalent to 32% extraction from the tailings.
The Extraction of Copper
Copper can be extracted from non-sulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to …
How is lithium mined? | MIT Climate Portal
Today, there are two main ways to pull lithium from the ground. Until recently, most lithium mining occurred in Chile, where lithium is extracted from brines: salty liquid found at the Earth's surface or underground. To extract lithium, that liquid is pumped from the earth and then placed in pools where the water can evaporate, leaving behind ...
