2001) conducted a grlass house experiment on alfalfa to evaluate the effectiveness of four B fertilizers; Granubor, Hydroboracite
, Ulexite and Colemanite.
Kinetics Modeling of Hydroboracite
Dissolution in Nitric Acid Solutions
But what the miner did not know, and you did, is that one of the specimens is mostly hydroboracite
and not colemanite, and is the finest specimen of that mineral known.
More than 230 different types of boron minerals are known in nature, but the number having commercial importance is limited to the following: tincal, colemanite, kernite, ulexite, pandermite, boracite, szaibelyite and hydroboracite
