The presence of REE tetrad effects in apatites and whole rocks of S-type granites has been reported by Sha and Chappell (1999) and Zhao et al.(1999), respectively. The REE tetrad effect in minerals, such as apatite, spessartite, beryl, alkali feldspar and spodumene, from all zones of Altay No. 3 pegmatite has been found remarkable, and the fractionations among isovalent incompatible elements in these minerals are also significant. This paper puts forward that the REE tetrad effect is one of the basic features of peraluminous melts and the origin of REE tetrad effect might be probably related to some processes prior to the formation of pegmatite magma. The immiscibile liquid separation between silicate melt and hydrosaline melt may be responsible for it.

由于阿尔泰3号伟晶岩脉各带磷灰石以及与其共生的石榴石、绿柱石、碱性长石、锂辉石矿物均存在明显的稀土"四重效应"以及相同电价、相似离子半径的不相容元素间存在显著的分异，并结合最近赵振华等(1999)和Sha and Chappell(1999)报道S型花岗岩全岩和单矿物(磷灰石、独居石、长石、黄玉等)均存在稀土"四重效应"这一现象，本文研究提出，稀土"四重效应"是富挥发分过铝质岩浆体系的一个基本特征，其机制既不可能由含稀土的副矿物早期结晶引起残余熔体相中REE含量变化的结果，也不能定性地归因于流体相与熔体相相互作用过程中稀土元素在流体/熔体之间分异的结果，而很可能与伟晶岩岩浆形成之前某些过程密切相关，S型花岗岩岩浆在液相线以上存在硅酸盐熔体与高盐熔体的不混溶液相分离有可能是过铝质岩浆体系产生稀土"四重效应"的主要原因。

The results show that quartz cannot react with oleic irons at pH=8-10, because it is difficult to combine with metallic irons. On the contrary, clinochlore can adsorb with oleic ions because there are enough active metallic positive ions between the minerals layers which can combine with clinochlore. The clinochlore can be hydrophobic, and so the separation can be realized finally. At pH=9, the clinochlore removal rate is the maximum, the purity of SiO2 is 99.86%, and the recovery of SiO2 is 35%.

结果表明：在pH为8~10的碱性溶液中，粉石英难与金属阳离子缔合，所以，不与油酸根离子结合；而斜绿泥石解离后层间存在活性金属阳离子，可与油酸根离子发生化学吸附产生疏水作用，因而使用反浮选的方法能有效地实现二者的分离：当pH为9时，斜绿泥石的去除率最高，粉石英的纯度达99.86%，回收率为35%。
