摘要： PURPOSE: A recovery method of SiC and/or Si solid particulates is provided to be able to separate and collect solid particulates with relatively large particle size from liquid containing SiC or Si solid particulates, and to collect all solid particulates by efficiently separate super fine solid particulates which have smaller particle size than the solid particulates from liquid. CONSTITUTION: A recovery method of SiC and/or Sic solid particulate comprises the following steps: a step of separating and collecting solid particulates of relatively large particle size among solid particulates from liquid containing SiC and/or Si solid particulates by the centrifuge and/or liquid cyclone, and discharging remaining liquid with solid particulates of relatively small particle size; and a step of collecting aggregates by adding an organic coagulant to the discharged liquid, and centrifuging or filtering the liquid containing aggregates formed by coherence of the solid particulates of relatively small particle size. The organic coagulant is a cationic organic coagulant described in chemical formula 1. In chemical formula 1, R1 is hydrogen or methyl group, R2 is alkyl group of 1-10 carbons, X is one halide selected from Cl, Br and F, a is the number of 0-10, b is the number of 1-10, m is the number of 3 and bigger.
摘要翻译：目的：提供SiC和/或Si固体颗粒的回收方法，以便能够从含有SiC或Si固体颗粒的液体中分离收集具有相对较大粒度的固体颗粒，并通过有效分离超细固体收集所有固体颗粒具有比液体的固体颗粒更小的颗粒的颗粒。构成：SiC和/或Sic固体颗粒的回收方法包括以下步骤：通过离心机和/或分离从含有SiC和/或Si固体颗粒的液体中分离和收集固体颗粒中固体颗粒的固体颗粒的步骤液体旋风分离器，并用相对较小粒度的固体颗粒排出剩余液体; 以及通过向排出的液体中添加有机凝结剂来收集聚集体的步骤，以及对通过相对较小粒径的固体微粒的相干形成的含有聚集体的液体进行离心或过滤。有机凝结剂是化学式1中所述的阳离子有机凝结剂。在化学式1中，R1是氢或甲基，R2是1-10个碳的烷基，X是一个选自Cl，Br和F的卤化物，a是数量为0-10，b为1-10，m为3以上的数量。
