Diatomite is a kind of siliceous rock, mainly distributed in China, USA, Japan, Denmark, France, Romania and other countries. is a kind of biological genesis of siliceous sedimentary rocks, which consist mainly of the remains of ancient diatoms. Its chemical constituents are mainly SiO2, which can be SIO2·NH2O indicated that the mineral composition is egg white stone and its variants. [1] China's diatomite reserves of 320 million tons, the long-term reserves of more than 2 billion tons, mainly concentrated in east China and the northeast region, of which large scale, more reserves of Jilin (54.8%), of which Jilin Province Linjiang proven reserves accounted for the first in Asia. ), Zhejiang, Yunnan, Shandong, Sichuan and other provinces, although the distribution is wide, but the quality of soil concentrated in Jilin Changbai Mountain area, the majority of other deposits are $number-grade soil, due to high impurity content, can not be directly deep processing and utilization.
