Lithium extraction process
New Section
The speaker introduces the idea of studying before playing a game and suggests adapting the game to the production of lithium.
Studying Before Playing
- The speaker suggests studying first before playing a game.
- They propose adapting the game to focus on the production of lithium.
New Section
The speaker discusses the process of extracting brine from Salar de Atacama and its use in producing lithium.
Brine Extraction Process
- Brine is extracted from Salar de Atacama through a pumping system.
- The brine comes from over 370 meters deep in the earth.
- Solar evaporation is used to concentrate the minerals in the brine.
New Section
The speaker explains that solar evaporation causes high concentration of salts in Salar de Atacama, which are then processed for lithium production.
Solar Evaporation and Salt Concentration
- Salar de Atacama has one of the highest evaporation rates and lowest precipitation rates.
- Solar energy is used to evaporate the brine and concentrate minerals.
- Salts go through multiple evaporation pumps to obtain a concentrated product rich in potassium sulfate, sodium, and magnesium.
New Section
The speaker highlights that only a small amount of water is required for the process and completes sentences about salar de atacama's unique characteristics.
Water Usage and Unique Characteristics
- Only 4% of total water available is used in this process.
- Salar de Atacama has high evaporation rates and low precipitation rates.
- This allows for efficient use of solar energy for evaporation.
- Salar de Atacama is known for its high concentration of salts and minerals.
New Section
The speaker completes sentences about the evaporation and concentration process in Salar de Atacama.
Evaporation and Concentration Process
- Solar radiation and wind aid in the evaporation and concentration of salts.
- Salts are transferred from one evaporation pump to another using a pumping system.
- The final solution of potassium salts undergoes a precipitation process.
- It takes about one year to obtain high-concentration lithium carbonate.
New Section
The speaker explains the chemical processing of lithium carbonate at the lithium carbonate processing plant.
Chemical Processing of Lithium Carbonate
- Purified and concentrated solution reacts chemically with sodium carbonate.
- This reaction produces high-concentration lithium carbonate.
- The lithium carbonate is then filtered, washed, dried, and packaged for distribution.
New Section
The speaker discusses various uses and applications of lithium carbonate.
Uses and Applications of Lithium Carbonate
- Lithium carbonate is used in rechargeable lithium batteries for laptops, mobile phones, digital cameras, etc.
- It is also used in ceramics, glass, cement, special coatings, cooktop glass, etc.
New Section
The speaker explains the production process of lithium hydroxide using raw materials like leaking carbon cell lithium carbonate and calcium hydroxide.
Production Process of Lithium Hydroxide
- Raw materials such as leaking carbon cell lithium carbonate and calcium hydroxide are mixed to produce lithium hydroxide.
- The same process also yields calcium carbonate.
- Lithium hydroxide is obtained in technical grade and battery grade.
New Section
The speaker explains the difference between technical-grade and battery-grade lithium hydroxide and their respective uses.
Technical Grade vs. Battery Grade Lithium Hydroxide
- Technical-grade lithium hydroxide is used in lubricant production for extreme conditions of load and temperature.
- Battery-grade lithium hydroxide is used in rechargeable lithium batteries, particularly in electric vehicles.
New Section
The speaker mentions FQM as a worldwide leader in the lithium industry and discusses reserves with high concentrations of lithium.
FQM and High-Concentration Reserves
- FQM is a global leader in the lithium industry.
- They have reserves with the highest concentration of leaking (lithium) in the world.
- These reserves allow for continuous production.
