· The conventional lithium extraction method involves the calcination of a-spodumene at 1050 °C so that it can be converted to the more-reactive b-spodumene and then a sulfuric acid roasting step at 250 °C. Lithium is finally extracted via leaching with water. This method is energy-intensive, leading to high capital and operational costs. In

Our direct lithium extraction (DLE) process recovers lithium from brine through selective absorption, before reinjecting the brine into the ground. It’s an efficient, validated new method based on proprietary technology. See how IBAT’s DLE method works. But perhaps the most revolutionary aspect of IBAT DLE is how green it is.

· Spodumene is the main source of lithium among the lithium-containing minerals. A number of studies have been done on the extraction of lithium from naturally occurring α-spodumene as well as pre-treated β-spodumene and the effect of key factors that influence extraction and optimum processing conditions have been discussed.

· 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
