Composition formed of mercaptans which can be used in a process for the flotation of ores

摘要

Composition intended for the flotation of ores, comprising: from 70 to 95% of a combination (A) of n-dodecyl mercaptan (or NDM) and of tert-dodecyl mercaptan (or TDM), the NDM/TDM ratio by weight of which is between 0.5 and 1.5, and from 5 to 30% of a product (B) composed of one or more aromatic or aliphatic compounds comprising from 4 to 100 carbon atoms, preferably from 5 to 40, and having one or two -OH groups. Process for the recovery by flotation of metal compounds of value present in ores employing it.
