1. A flotation agent for phosphate ore, comprising at least one fatty acid and at least one sarcosinate of the formula (I)wherein R is a C7 to C21 alkyl or alkenyl group, wherein the sarcosinate may be present in the form of a cation derived therefrom, caused by protonation of the nitrogen atom, wherein the amount of fatty acid is from 80 to 99 wt.-%, and wherein the amount of the sarcosinate of the formula (I) is from 1 to 20 wt.-%. |
