Processing of boric acid from borax by a wet chemical method

Production of crystalline boric acid and sodium citrate from borax decahydrate

“…It is widely used in industrial applications, such as glass, ceramics, textiles, detergents, and nuclear power, as well as in the agricultural, medical, pharmaceutical and electronicsrelated sectors. Moreover, it is used as a raw material in the preparation of many boron chemicals, such as zinc borate, boron esters, boron carbide, boron nitrite, boron phosphate, boron trihalides, organic boron salts, and fluoroborates) (Valdez et al, 2014;Cavus and Kuslu, 2005;Mergen et al, 2003).…”

“…The production cost is very high because strong acids shorten the life of the equipment. In addition, the use of high concentration of acid results in the use of high concentrations of sulfuric and hydrochloric acid results in the presence of high concentrations of sulfate and chloride ions which compromise the quality of boric acid crystals (Ciftci, 2012;Mergen et al, 2003). Therefore, organic acids may be an alternative to inorganic acids for use in the production of boric acid.…”

Dissolution kinetics of ulexite in acetic acid solutions

“…The preferred commercial method of preparing boric acid is by way of digestion of alkali and alkaline earth metal borates with concentrated mineral acids followed by crystallization of boric acid (Shiloff, 1968;Taylan et al, 2007). In Turkey, boric acid is obtained from the reaction of colemanite and sulfuric acid in accordance with heterogeneous solid-liquid reaction (Mergen et al, 2003). In this process, gypsum forms as a by-product and precipitates in the reactor while boric acid remains in the liquid phase throughout the reaction.…”

Effects of sodium roasting on the leaching rate of boron-bearing tailings and its mechanism analysis

“…As an important ore resource, boron deposit is the basic raw material for the production of borax [1,2], boric acid [3,4] and a series of other boron and boride products [5,6], which are widely used in fields such as chemicals, metallurgy, building materials, electrical appliances, machinery, agriculture, nuclear industry and medicine [7–10]. The global boron ore resources are relatively concentrated, and there are few countries with boron resources.…”
