A review of lithium extraction from natural resources
The lime roasting method is the earliest method used to extract lithium from spodumene [27]. Spodumene is mixed with lime or limestone for roasting. Sufficient amount of CaO destroys the mineral structure at high temperatures over 1100°C [28–29]. The roasting reaction is shown in reaction (1). The calcine is leached to obtain the LiOH solution.

A lot of the solids produced by an ocean capture plant could ...
23.2: Principles of Extractive Metallurgy
— The process isolates the impurities that concentrate in the molten zones, leaving the portions behind them somewhat more pure. This process is repeated until impurities are moved to the end of the rod and cut off, resulting in an almost completely pure metal rod. Figure (PageIndex{4}): The Zone refining method. from Binod Shrestha.
Extraction of Iron: Meaning, Purification, & Extraction Methods
— Most of the molten iron from a Blast Furnace is used to make different types of steel. Calcination is the process of converting ore into an oxide by heating it strongly. The most important iron ore is hematite. The iron extraction process is a long process that begins with calcination and is then followed by a few major steps.
