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

摘要

Composition comprising 70 - 95% of a combination of (A) n-dodecyl mercaptan (NDM) and tert-dodecyl mercaptan (TDM) in which the weight ratio NDM/TDM is 0.5-1.5, and 5 - 30% of a product (B) comprising one or aromatic or aliphatic compounds with 4-100 C and having one or two hydroxyl groups. An independent claim is also included for the process of ore recovery by flotation using the additive described.
