Borax slime is formed during the production of borax from tincal, whic
h is an important berate ore. It is a liquid containing the suspanded
solid particles at high levels and is formed under the rich-in-borax s
olution in the reactor. This waste is discharged into the Marmara Sea
and so causes environmental problems in Bandirma Golf. In this work, B
orax production is aimed from the slime containing B2O3 at important l
evels. As a result it was found that B2O3 can be recovered and therefo
re the B2O3 pollution can be prevented by removing it from the waste.
