摘要： This invention relates to highly purified biogenic silica product obtained from diatomite and methods for preparing same. More particularly, this invention pertains to highly purified non-calcined, calcined, and flux-calcined diatomite products which bear the distinguishing porous and intricate structure of silica unique to diatomite and which have an extraordinarily high silica (i.e., silicon dioxide, SiO.sub.2) content and low density, resulting in high silica specific volume. These products often also exhibit exceptionally low soluble metals content and/or extreme brightness.
摘要翻译：本发明涉及由硅藻土获得的高纯度生物二氧化硅产品及其制备方法。更具体地说，本发明涉及高纯度的非煅烧，煅烧和助熔煅烧硅藻土产品，它们具有硅藻土独特的二氧化硅的多孔和复杂结构，并具有非常高的二氧化硅（即二氧化硅，二氧化硅）含量低密度，二氧化硅比体积高。这些产品通常也表现出非常低的可溶性金属含量和/或极度亮度。

摘要： Disclosed herein is a method for processing diatomaceous earth ore comprising roasting a diatomite feed at a temperature ranging from about 850 to about 1600° F. Also disclosed herein is a method for processing a diatomite feed comprising at least one impurity to produce a diatomite product having at least one of reduced loss-on-ignition, reduced impurity content, reduced beer soluble iron content, and improved brightness as compared to the feed composition. Further disclosed herein is a system for processing a diatomite feed comprising a first heating zone for roasting the diatomite at a temperature ranging from about 850 to about 1600° F., a second zone for calcining the diatomite at a temperature of at least about 1600° F., and a counter-current flow of gas from the second heating zone to the first heating zone.
摘要翻译：本文公开了一种处理硅藻土矿石的方法，其包括在约850至约1600°F的温度范围内焙烧硅藻土原料。本文还公开了一种处理包含至少一种杂质的硅藻土原料的方法，以产生具有与进料组合物相比，降低的点火损失，杂质含量降低，啤酒可溶性铁含量降低和亮度提高中的至少一种。本文进一步公开的是一种用于处理硅藻土原料的系统，其包括用于在约850至约1600°F范围内焙烧硅藻土的第一加热区，用于在至少约1600℃的温度下煅烧硅藻土的第二区以及从第二加热区到第一加热区的逆流电流。
