boron is a volatile element, readily transported by hydrous fluids, which are prevalent in and on the continents. As a consequence, important con-centrations of boron and boron minerals are common in many types of hydrothermal ore deposits and in evaporitic borates, the latter being the most important commercial source of boron.

The most important boron ore that is extracted is ulexite, associated with tincal . In Peru, there is only one company that extracts natural borates from the Laguna Salinas deposit, where reserves are estimated at 10 Mt. of ore with 25–27% of B 2 O 3. The open-pit mine is about 80 km away from Arequipa at an altitude of 4100 m.a.s.l.

Boron combines with oxygen and other elements to form boric acid or inorganic salts called borates. Boron compounds, chiefly borates, are commercially important; therefore, boron products are priced and sold based on their boric oxide (B 2 O 3) content, varying by ore and compound and by the absence or presence of calcium and sodium.

10.3.4 Boron Isotopes in Magmatic-Hydrothermal Ore Deposits. Boron is an element readily mobilized by aqueous fluids, and many hydrothermal ore deposits are associated in one way or another with boron metasomatism, which is expressed most commonly in the form of tourmaline (e.g., Slack 1996; Slack and Trumbull 2011).

Ludwigite ore is a typical low-grade boron ore accounting for 58.5% boron resource of China, which is mainly composed of magnetite, lizardite and szaibelyite. During soda-ash roasting of ludwigite ore, the presence of lizardite hinders the selective activation of boron. In this work, lizardite and szaibelyite were prepared and their soda …

The ore is crushed and blended to a concentration of 8.6% boron oxide. The datolite is not soluble and the ore is washed to remove gangue after crushing. Decahydrate borax is also produced by the reaction of boric acid with sodium carbonate (soda ash) as follows: 4H3BO3 + Na2CO3 + 4H2O ⇒ Na2B4O7·10H2O + CO2
