摘要

对皮切姆斯科油田硅钛精矿湿法脱硅过程中石英的溶解进行了研究。在CaO - SiO2 - na2o - h2o体系中，由于二氧化硅与水合硅酸钙结合，特别是与CaO·SiO2·nH2O结合，发生了精矿脱硅。测定了温度、反应时间、CaO / SiO2比、NaOH含量等影响硅酸钙水合物中硅灰石精矿脱硅结晶程度的主要因素。

Effects of Desilication Conditions on the Formation of Wollastonite during the Autoclave Leaching of Silica–Titanium Concentrates

The dissolution of quartz during the hydrometallurgical desilication of silica–titanium concentrates from Pizhemskoe field (Komi Republic) was studied. The concentrate desilication occurs in the CaO–SiO₂–Na₂O–H₂O system due to the binding of silica into calcium silicate hydrate, in particular, into CaO·SiO₂·nH₂O. The main factors (temperature, duration, CaO : SiO₂ ratio, NaOH content) governing the extent of concentrate desilication and crystallization of wollastonite from calcium silicate hydrates resulting from the reaction were determined.
