硅藻土矿床是由硅藻遗骸沉积形成的矿床。硅藻土的硅藻含量大于80%,SiO2>75%。硅藻壳体含量为70%~80%,SiO265%~75%时,称为含粘土硅藻土;硅藻壳体含量55~65%,SiO260%左右的则称粘土质硅藻土。
云南先锋硅藻土矿是我国的一个特大型硅藻土矿床。
The Xianfeng diatomite deposit in Yunnan is the largest deposit in our country, which is featured of thick layers.
先锋硅藻土矿床,蛋白石含量低,烧失量高,但是,硅藻土矿厚度大,储量大,充分利用先锋硅藻土矿有深远的重要性。
Although the opal content of Xianfeng diatomaceous deposit is low and burning loss is high, its thickness and reserve are big, therefore, fully using this diatomaceous deposit is very imu...
