What is it?

Humic acid is a group of organic compounds

formed by the association of high-molecular mass

substances from microbiological, vegetative and

animal origin.

They are organic macromolecules with multiple

properties and high structural complexity.

They exist abundantly in soil, natural water,

lignite and aquatic environments.

How it is made?

Coal is ground and filtered through 60 mesh sieve.

It is treated with oxidizing agent by adding portions in small doses at specific intervals not allowing the temperature to rise above 40OC, external cooling as the oxidation stage is exothermic.

The residue is filtered and treated with a mild alkali.

The water soluble salt of humic acid thus formed goes into solution, with is filtered to separate it frominsoluble inorganic residue.

It can be dried in trays or the humic acid can be precipitated back by acid treatment.

Applications

Humic acid utilization can be very economical

for agricultural crops, due to availability of very

cheap indigenous raw material in the form of

lignitic coal and indigenous production

technology

Imports into India

Recently in 2014 India imported humic acid worth USD 3,404,733 with total quantity of 4,929,168. China is the largest supplier of humic acid accounting for imports worth USD 3,134,406 followed by United States and Canada which exported humic acid worth USD 133,216 and USD 67,057 respectively.

Chennai Sea accounted for 49.3% of imports followed by Nhava Sheva Sea and Kolkata Sea which account for 35.4% and 7.8% of imports respectively.

Average price of humic acid per unit is USD 0.69 and average value per shipment is 9,700
