摘要
Froth floatation possesses the advantages of simplicity, rapidity, and high efficiency. It may be divided into two classes: ion and precipitate floatations. At present, the enrichment factor for ion floatation of gold is 30, or the sample is enriched to a concentration of 5×10<sup>-4</sup> mol. Our procedure attains an enrichment factor not less than 102, while the time does not exceed half an hour.
