Definition and Usage Areas:
Boric acid, also boracic acid, orthoboric acid or acidium borium; A white crystalline, water-soluble inorganic acid often used in antiseptics, pesticides, and deodorizers. And also, It first discovered by Wilhelm Homberg and emerged as a by-product of sulfuric acid.
Production of boric acid from colemanite
Boric acid mainly produced from colemanite in Turkey. It is production by Etibank. Furthermore, The production process basically consists of the reaction of colemanite with sulfuric acid. As shown below, gypsum and boric acid both formed as a result of the reaction. Gypsum formed during production causes environmental pollution.
Ca2B6O11.5H2O + 2H2SO4 + 6H2O → 2CaSO4. 2H2O + 6H3BO3
Firstly, in production colemanite is ground in mills with a size of <0.2 mm. Meanwhile, Ground colemanite is taken into solution by reacting with sulfuric acid. This reaction takes place at 80-100 oC.
Crystallization of Boric Acid
The colemanite solution obtained after filtration which fed to the crystallizer at a constant flow rate. The solution coming to the crystallizer is sprayable with special sprays and spread to the crystallizer. In this way, the size of the formed crystals increases and the process continues more efficiently. The factors affecting the crystal size are the density of the fed solution and the solids in the solution.
Filtration of Boric Acid
After colemanite is taken into solution with acid, gypsum mud is formed due to chemical reaction. In order to remove this gypsum from the environment, it is necessary to filter the solution with pressure filters. For this purpose, two-stage filtration should take into consideration when performed. Thus, In the first stage, the entire solution will soak for 15-20 minutes. filtered throughout. The filtrate, which has passed the first stage, should filter in another pressure filter for about 3 hours in the second stage. Eventually, The gypsum mud obtained as a result of these stages should send to the residual pool.

Boric Acid Applicable Area
- Boric acid is one of the most widely produced borates and is widely used in the pharmaceutical and cosmetic industry, in the manufacture of glass and fiberglass, as a nutritional additive, flame retardant, and in the manufacture of wood preservatives to control pests.
- It is non-toxic with antibacterial properties and often used as an antiseptic agent, acne treatment, preservative, insecticide, pH buffer, swimming pool chemicals, flame retardant and precursor to many other beneficial chemicals.
- Industrially, fiberglass is usable to manufacture glass used in household glassware and LCD displays.
