| titleOfInvention | How to make white coal |
| abstract | The present invention relates to a process for producing a kind of white coal (non-pure silicon dioxide comprising at least 93% SiO 2 ). According to this method, an appropriate amount of seawater is added to sodium silicate and sufficiently wetted at room temperature and normal pressure. As such, the sodium silicate separates silicon dioxide to be treated with powdered white coal, while sodium oxide is dissolved in seawater. The present invention has the following advantages. It is possible to produce large quantities of white coal in an economical way. Its discharged waste also does not pollute the surroundings.n n n And the white coal produced by this method is alkaline, and the quality of its byproducts is improved. |
