Can you explain the potassium humate production process?

The production of potassium humate involves the extraction of humic acid from natural organic materials like leonardite or lignite. The process includes:
Extraction: Leonardite is treated with a strong alkaline solution, such as potassium hydroxide (KOH), to dissolve the humic substances.
Filtration: The humic acid-rich solution is filtered to remove impurities and unreacted materials.
Neutralization: The solution is neutralized to stabilize the potassium humate product.
Drying: The liquid potassium humate can be dried to produce powder or granules, or it can be left in a liquid form.
Packaging: The final product is packaged as liquid, powder, or granules for agricultural use.
The entire process is designed to maximize the concentration of active humic substances in the final product, ensuring effectiveness in farming applications.
