Filed: 1991-10-25
Abstract: PURPOSE:To easily provide high purity and high quality by heat-treating vermiculite at high temperature to foam it and thereafter removing impurities by elutriation. CONSTITUTION:Vermiculite of 1-10mm particle diameter is introduced into a furnace at about 700 deg.C and foamed to obtain foamed vermiculite 1. Then this foamed vermiculite 1 is introduced into a vessel A which is filled with water 4 and opened in the upper part. A foamed vermiculite layer B is obtained by floating the foamed vermiculite 1 so that thickness thereof is regulated to 1-50mm. Then, after water is violently agitated for 1-2 minutes so that the vermiculite 1 is sunk underwater, it is allowed to stand for 1-2 minutes to sink impurities 3 such as pyroxene and feldspar and unfoamed vermiculite in the bottom part. Such states (C), are obtained that only purified and foamed vermiculite 2 of high purity remains on the water surface 5. Then only the purified vermiculite 2 floated on the water surface is recovered by using elutriation. The obtained vermiculite is dried at 400-800 deg.C to produce the purified vermiculite.
