· Elevated temperature and pressure are very necessary in the leaching process because many lattice elements are enriched around crystal interfaces. The processing technique of quartz sand using hot phosphoric acid has been focused on in recent years due to its low cost, high efficiency, and "green" property [87,88,89].
acidic leaching stage and oxalic acid as a reducing agent in the quartz purifiion process as they are more economical than the other chemicals, while also being effective in removing Fe 2 O 3 .
A process is disclosed for the hydrothermal production of potassium silie solutions with high SiO 2 :K 2 O molar ratios, by the hydrothermal reaction of quartz sand with aqueous potassium hydroxide solutions at temperatures in the range of 150° to 300° C. at the pressures of saturated water vapor corresponding to these temperatures in a pressure reactor, which is characterized in that the ...
