摘要
绢云母中含铁量多少是影响产品品质,特别是白度的重要因素,对滁州产出的绢云母的显微结构、化学组成、谱学特征、Fe含量分配等一系列特征进行了分析研究,结果表明,矿物中大部分Fe存在于二八面体中,并且得出其含量分配系数。研究结果对绢云母的具体加工和生产有指导作用。
The contents of Fe in sericite would influence the quality ofsericite products significantly, especially their whiteness. In this paper, microscopic observation, chemical composition, XRD, EPR spectraand contents of Fe for sericite from the Chuzhou Mica Mine were carried out. It is concluded that the main fraction ofFe inthe ores and minerals occurs atthe dioctahedral siteof sericite. The representativepercentages of Fe distributed in rock-forming minerals werealso measured. The results are helpful toguide industrialproductionandprocess in this area.
