白土坡膨润土产于第四系下更新统中,矿层稳定、厚度较大,为钙基膨润土,主要矿物成分为蒙脱石,含量35.7%～46.8%,其他矿物有石英、高岭石等。矿石中Fe2O3含量为5.72%～6.51%,白度为26.5%～34%。原矿工艺技术性能达到铸造用膨润土工业指标要求。初步提纯后蒙脱石含量达55.2%～69.3%,钠化处理后湿压强度为0.18kgf/cm2～0.27kgf/cm2,热湿拉强度为17.8gf/cm2～22.4gf/cm2,活化后脱色力110～113,活性度为188mmol～191mmolH/kg,游离酸含量0.1%。白土坡膨润土可用作铸造用砂粘结剂、钻井泥浆材料、纺织印染材料、矿物饲料添加剂、建筑涂料、球团粘结剂等。
The bentonite is produced in the Quaternary Lower Pleistocene. The ore bed is stable and thick with calcium bentonite. The main mineral composition is montmorillonite with the content of 35.7% ~ 46.8%. The other minerals include quartz and kaolinite. Fe2O3 ore content of 5.72% ~ 6.51%, whiteness of 26.5% to 34%. Raw ore technology performance reached the casting bentonite industrial indicators. After initial purification, the content of montmorillonite reaches 55.2% ~ 69.3%, the wet compressive strength after sodium treatment is 0.18kgf / cm2 ~ 0.27kgf / cm2, the thermal wet tensile strength is 17.8gf / cm2 ~ 22.4gf / cm2, Power 110 ~ 113, activity of 188mmol ~ 191mmolH / kg, free acid content of 0.1%. White soil slope bentonite can be used as foundry sand binder, drilling mud material, textile printing and dyeing materials, mineral feed additives, architectural coatings, pellet binder.
