In this study, the effect of sodium dodecyl sulfonate (SDS), as a well-known flotation collector, on talc grinding was investigated using a statistical design in terms of solids%, pH, grinding time, and SDS dosage taking the d₈₀ of the ground product as a response. The results indicated that the factors under study significance order were grinding time > solids% > SDS dosage > pH. In addition, the interactions between solids % and the grinding time and between the solids% and SDS dosage significantly affected the product d₈₀. More interestingly, the presence of SDS not only improves the grinding process at short grinding times but also it enhances the grinding at higher pH values. The optimum conditions for talc grinding are similar in the absence or presence of SDS in terms of factors under study, except for solids%. The vital role of SDS, as a grinding aid, is the production of particles with the same fineness or even finer at higher solids % which leads to an increase in the mill throughput. The smallest d₈₀ was obtained at 60% solids, 60 min, pH 4, and 2 kg t⁻¹ of SDS.

十二烷基磺酸钠存在下滑石粉研磨的各个方面

在这项研究中，钠十二烷基磺酸钠（SDS）的效果，作为公知的浮选捕收剂，滑石研磨，使用在固体％，pH值方面具有统计设计，研磨时间的调查，和SDS剂量服用d ₈₀的地面产品作为响应。结果表明，研究显着性顺序的因素是研磨时间>固体％>SDS用量>pH值。此外，固含量百分比与研磨时间之间以及固含量百分比与 SDS 用量之间的相互作用显着影响了产品 d ₈₀. 更有趣的是，SDS 的存在不仅改善了短研磨时间的研磨过程，而且还增强了在较高 pH 值下的研磨。就所研究的因素而言，滑石粉研磨的最佳条件在不存在或存在 SDS 的情况下是相似的，但固体百分比除外。作为助磨剂的 SDS 的重要作用是生产具有相同细度甚至更高固含量的颗粒，从而提高磨机产量。最小的 d ₈₀是在 60% 固体、60 分钟、pH 4 和 2 kg t ^-1 SDS 下获得的。
