Pa. Galushkov et Ai. Elshin, RECOVERY OF BORON FROM GAS-PURIFICATION SYSTEM SOLID-WASTES, Journal of applied chemistry of the USSR, 65(10), 1992, pp. 1953-1954
A leaching technique is described for recovering boron from the wastes
derived from gas-purification systems used in glass manufacture. Extr
action from the boron-containing wastes reached a level of 90-95%.
