The results of XRD analysis and whole pattern fitting quantitative calculation indicate that the sample for this study from Linze,Gansu is composed of palygorskite 70.1%,ankerite 15.7%,quartz 6.6% and a small amount of muscovite,albite and chlorite.Various methods were deployed to extract iodine from the ore.Heating-sublimation method extracted no iodine,illuminating that the occurrence of iodine in palygorskite is ionic rather than molecular.Hot water soaking can only extract an extraordinarily small quantity of iodine,about 0.76 to 2.05 μ g/g of the ore,indicating that the binding strength between iodine and palygorskite is exceedingly high,and the iodine is rather difficult to be activated by hot water.Iodine extracted from palygorskite by hydrochloric acid soaking were in the range of 190.4 to 320.5 μ g/g,positively related with the dipping time,but hardly affected by temperature.In the acid soaking period of 40 h,the correlated curve between extracted amount of iodine and time is in S-shape,i.e.,with a gentle initial and terminal,but a steep middle.The S-shape releasing curve indicates that iodine is predominantly from palygorskite,contribution of another major mineral phase dolomite is negligible,for that the later is dissolved in HCl solution very soon.The releasing curve also indicates that most of the absorbed iodine in palygorskite occurred in its intracrystal tunnel space,instead of on the external surface of the mineral.The high extracted ratio achieved by hydrochloric acid is related with the low acid stability of palygorskite.Releasing of iodine from the carrier took place simultaneously with the dissolution of the mineral.

XRD分析和全谱拟合定量计算结果表明,甘肃临泽含碘坡缕石矿的物相由坡缕石(70.1%)、白云石(15.7%)、石英(6.6%)以及少量白云母、钠长石和绿泥石组成。尝试采用了不同方法提取矿石中的碘。加热升华法未能使碘从坡缕石矿石中析出,表明碘在矿石中的赋存形式是吸附的离子态,而非分子态。热水浸取法从矿石中提取出的碘十分有限,仅为0.76~2.05μg/g,显示碘与坡缕石结合十分牢固,难以被热水活化。盐酸浸取法从矿石中提取出的碘为190.4~320.5μg/g,提取量与盐酸浸泡的时间成正比,与温度关系不大。在40h的酸浸泡时间内,碘提取量与盐酸浸泡时间的关系曲线呈S型,即初期和末期平缓,而中段较陡。碘释放的时间曲线说明,碘主要来自坡缕石,而非另一主要矿物白云石,因为后者很快被盐酸溶解;此外,盐酸提取碘的时间曲线还表明,甘肃坡缕石中的碘最有可能赋存在载体矿物的晶内隧道孔中,而非矿物表面。盐酸浸取法提取效果好与坡缕石的酸稳定性较差有关,碘的活化与载体矿物被盐酸溶蚀基本同步。
