The process of quicklime slaking involves converting calcium oxide into calcium hydroxide (Ca(OH)2) or slaked lime by adding water to create a lime slurry. It can also be purchased as powdered slaked lime. Hydrated or slaked lime is commonly used in mining and processing industries. Uses include: Water treatment Temperature control pH control
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 ...
