STUDIES OF PURIFYING OF CLAYEY DIATOMITE郑水林摘 要:<正>This article discusses the purifying method of the clayeydiatomite or cler-bearing diatomite minerals found in China.And theprocesses of acidizing,beneficiation and gravitational fluidized dry sepa-ration are reviewed.关键词:......
production using diatomite as a raw material were presented in the following article. A mixture of diatomite and 40% NaOH solution was subjected to heating at a constant temperature of 775 ℃. Samples of foam glass-ceramic from diatomite with an average density of 290-580 kg/m3, compressive strength of 1.7-7.8 MPa and thermal conductivity of 0.08-0.14 W/(m·K) were obtained. The investigations have shown......
