Reviewer 2 Report. This paper describes a straightforward study of the flotation of bastnaesite and the gangue minerals barite and calcite.
In order to improve the flotation separation efficiency of bastnaesite from barite and calcite, a novel collector, octylamino-bis-(butanohydroxamic acid) (OBHA), with large molecular structure and two functional groups was synthesized based on the molecular design of flotation reagents theory.OBHA was adopted as collector in both single, mixed binary and mixed ternary mineral flotation…
The flotation separation of scheelite and barite is difficult because they have the same active sites. The surface transformation of semi-soluble minerals is inevitable in the flotation of salt minerals, but an effective flotation separation can be achieved through the dissolution and surface transformation of fluorite. In the current flotation test, fluorite particles and sodium fluoride are ...
The flotation method must be used for the separation of fine barite ore and gravity separation tailings. The main barite flotation processes are positive flotation process and reverse flotation process, in which the purpose of the reverse flotation process is to remove the alkali sulfide.
recleaning steps on the recovery of the barite. General Test Procedure A one kilogram sample of barite ore was ground in a laboratory sized rod mill for five minutes at 50 percent solids.

Barite deposit at Mangampet is one of the world's largest deposits containing around 61 million tonnes of recoverable barite. Beneficiation of low grade barite dumps interlocked with schist and slate gangue was studied using amine as collector (reverse flotation) to avoid the collector coating on barite. Instead of conventional flotation cells, flotation column was opted due to inherent ...
