On the mechanism of boron accumulation in oceanic metalliferous sediments

Experiments were carried out to study boron co-precipitation with iron hydr oxide from seawater. The high efficiency of boron removal from the solution s is ascertained. It is shown that the B/Fe ratio in the precipitated iron hydroxide is higher by an order than that in the exhalation component of me talliferous sediments. It is supposed that the removal of the sorbed boron takes place in the course of the aging of iron hydroxide at the stage of di agenesis.
