    1/5/2018· Oleoyl sarcosine. Oleoyl sarcosine is used as a selective collector both in the flotation of fluorite in calcitic gangue [52] and of scheelite in siliceous gangue [19], [53]. Its selectivity for scheelite against other calcium-bearing minerals is limited [53] but still greater than sodium oleate [54].
