Lithium deposits exist all over the world and are mainly found in sedimentary rocks, volcanic rocks and groundwater. Some of the countries with lithium mineral resources include Australia, Chile, Argentina, Zimbabwe, Puerto Rico, Canada and China.
The extraction of lithium from mines depends on the type of mine and the extraction method. Extraction methods include direct extraction from the mine, extraction through the hydrometallurgical process, extraction through the pyrometallurgical process, and extraction through the leaching process.
Due to its special chemical properties, lithium is used in many industries. One of the important uses of lithium is in the production of rechargeable batteries. Lithium batteries are one of the most popular types of rechargeable batteries used in today’s electronic devices such as cell phones, laptops, and digital devices.
In addition, lithium has various applications in the glass industry, metal industry, pharmaceutical industry, nuclear industry and petrochemical industry. For example, lithium compounds are used in the production of transparent and hard glass, and lithium carbonate is used in the production of aluminum alloys and in electrolysis processes.
Also, lithium is used as a medicine and is effective in the treatment of some mental disorders such as depression and bipolar disorder (bipolar affective disorder).
Lithium is used as an important element in the battery industry. Lithium batteries are a type of rechargeable battery that comes in different types, including lithium-ion batteries and lithium-polymer batteries.
Lithium-ion batteries usually consist of three main parts: the positive electrode (cathode), the negative electrode (anode), and the electrolyte material that is placed between these two electrodes. In lithium-ion batteries, lithium is present as a positive ion (Li+) in the electrolyte. When the battery is charged, the lithium ions move to the negative electrode and are stored there.
When the battery is discharged, lithium ions move from the negative electrode to the positive electrode, and this flow of ions creates an electric current that can be used as a power source for a variety of things, including cell phones, laptops, portable electronic devices, and other devices. .
Lithium-polymer batteries are also based on lithium technology. In this type of battery, the liquid electrolyte is replaced by polymer solids, which are more flexible and malleable. Lithium-polymer batteries are made thin and light and are used for some thin and flexible electronic devices such as smart watches and wearable devices.
Lithium batteries are used in many electronic devices with features such as high capacity, light weight, long service life and no need for continuous maintenance.
The world’s largest lithium mine is currently the Salar de Nora mine in Australia. This mine, located in the Western state of Australia, has one of the largest lithium deposits in the world. The Salar de Nora mine is operated by Pilbara Minerals and supplies a significant amount of global lithium production.
Cellar de Nora mine has high quality lithium deposits in spodumene rocks. The lithium extracted from this mine is used as a raw material for the production of rechargeable batteries that are used in various industries, including automotive and renewable energy.
Lithium ore, as one of the most important sources of lithium extraction, is mostly extracted as spodumene or lepidolite. Spodumene is one of the main lithium ores in which lithium is present in metallic form. . Sephardite usually appears in the form of large crystals and in the form of columns or plates. This rock is usually found in areas with faults and strong thermal changes.
Lepidolite is another rock that can contain significant amounts of lithium. This stone is usually purple or pink in color and can be found in large masses and small masses. In addition to lithium, lipidolite may contain other elements such as aluminum, potassium and light metals.
Extraction of lithium from ores is often done through processes such as crushing, grinding, and chemical processing.
Lithium extraction from mines is mainly done in the following ways:
In this method, lithium mine is first extracted as mineral soil and then a chemical process is performed to separate lithium from other elements. Various methods are used to separate lithium, but the more advanced and common process for extracting lithium from mines is the hydrometallurgical process. In this process, lithium ore is first transformed into lithium chemical compounds using chemical synthesis and pre-processing processes. Then, by means of hydrometallurgical processes, lithium is separated from other compounds and produced as pure chemical compounds of lithium.
Lithium is also extracted from natural sources of salt water. In this method, salt water is collected from seas, lakes and other sources of salt water. Then, using evaporation and condensation processes, salt water is purified in the form of lithium enrichment and concentration under certain pressure and temperatures.
Finally, lithium is separated from salt water and produced as chemical compounds or pure compounds. Extraction of lithium from mines or salt water may involve complex and costly processes. For this reason, lithium extraction is usually carried out in areas where there are rich resources of lithium and according to the economic conditions and available technology.
