3. Soak the pieces in water and mix them well.

4. Spin the mix to separate humic acid from other stuff.

5. Filter the liquid to clean it.

6. Remove water to make the humic acid stronger.

7. Dry it and put it in packages.

Most companies use the alkaline extraction method. They add special solutions to Leonardite. This helps get humic substances out. This way works best for Leonardite with lots of humic acid. You get a pure product that helps your soil.

Grinding

Grinding is very important in mining. It breaks Leonardite into tiny bits. This makes it easier to get humic acid out. Fine grinding helps the solution reach more Leonardite. You get more humic acid and better quality.

Well-ground Leonardite gives you a steady product. It helps the process work better. You can trust each batch to help your fields.

Tip: Ask your supplier how they grind Leonardite. Good grinding means you get the same results every time.

Humic Acid Extraction

Techniques

Catalytic Hydrogenation

You can use special steps to get better results from Leonardite. High-pressure catalytic hydrogenation is a top method. In this step, Leonardite goes into a high-pressure reactor. The reactor uses a catalyst and hydrogen gas. This changes the structure of Leonardite. The humic acid turns into graphene oxide-like nanosheets. These nanosheets have lots of carbon and less oxygen. You get a stronger product with better soil properties. This method helps you get more value from each batch. It also helps plants grow strong.

Note: Catalytic hydrogenation makes a better product. It can help your crops do well.

Solvent Use

You need to pick the right solvent to get humic acid from Leonardite. Alkaline extraction works best for this job. Here are some common solvents you might see:

• Sodium hydroxide (NaOH)

• Potassium hydroxide (KOH)

These solvents help take humic acid out of Leonardite. They work well and give a good yield. Most producers use these because they are reliable.

Some new methods use special membranes. For example, a permeation cell with a polymer inclusion membrane can clean fulvic acid from Leonardite. This method lets only the right molecules go through. It blocks unwanted ions and impurities. You get a cleaner product with less waste and lower costs.

Yield and Purity

You want to know how much humic acid you get and how pure it is. Industry leaders use systems that give high yields and purity. Here is a table that shows what you can expect from top commercial processes:

You can see the best systems give up to 90% yield and over 92% purity. These numbers show why you should choose trusted producers.

Industry leaders use standardized methods. They do not use old ways that give mixed results. They start with alkaline extraction. Then, they add acid to separate humic acid from fulvic acid. This gives accurate and repeatable results every time.

Tip: When you pick a supplier, ask about their extraction process. A good process means you get more humic acid and better results in your fields.

Purification

Centrifugation

Impurity Removal

You want your humic acid to be very pure. Centrifugation helps you do this. When you spin humic acid at 30,000 rpm, minerals separate from the organic part. This step keeps humic acid clean and strong. You do not want fake organo-mineral mixes in your product. Centrifugation helps you avoid these unwanted mixes.

You can trust this process to keep humic acid good. Minerals settle at the bottom, and organic matter stays in the liquid. You get a product that works better for your soil. Your crops grow better with cleaner humic acid. Soil microbes also do well because you remove bad minerals.

Here is a simple way to do centrifugation:

1. Put humic acid extract in the centrifuge.

2. Spin it very fast (30,000 rpm).

3. Minerals and heavy bits go to the bottom.

4. Take the clear liquid from the top.

5. Use the clean humic acid for the next step.

Tip: Ask your supplier if they use fast centrifugation. This step helps make the product very pure.

Filtration

Consistency

Filtration gives you humic acid that works the same every time. You want each batch to help your soil and crops well. Filtration removes tiny bits and leftover dirt. This step makes sure humic acid is clear and steady.

"Research shows humic acid can clog filters. This happens most in capillary pressure filtration. It slows down the process and lowers the quality of purified humic acid."

Sometimes humic acid blocks filters. Big pieces stick to the membrane and slow things down. This clogging can make the product less steady. You want to stop this problem.

"Studies found prefiltration helps a lot. It removes big clumps before main filtration. This makes the process work better and gives purer humic acid."

You can use prefiltration to fix this. By taking out big clumps first, you keep the system working well. Your humic acid stays clean and helps your fields.

"At first, clogging happens because big humic acid pieces stick to the membrane. This makes more clogging later and hurts the steady quality of the purified product."

You want a product that works the same every time. Filtration helps you reach this goal. You get humic acid that helps soil and crops stay strong. Steady results matter for your fields.

Here is a quick list for filtration:

• Use prefiltration to take out big pieces.

• Pick the right filter for humic acid.

• Check for clogging and clean filters often.

• Test each batch for clearness and purity.

You can trust these steps to get good humic acid. Your soil and crops will do better with a pure and steady product.
