dolomite flotation process set


Surface chemistry and flotation behavior of dolomite

In RE mineral flotation carboxylates such as fatty acids and sodium oleate is the most widely used type of collector 10 . However this type of collector also adsorbs to gangue minerals such as dolomite making them float as well 11 . The use of carboxylates would thus require dolomite depressants to make flotation efficient 12 .

Novel Technique for the Separation of Dolomite from

The dolomite separa tion feed is dewatered conditioned 20 30 seconds at a slightly acid pH with tallow amine acetate and diesel fuel and is then subjected to rougher cleaner and re cleaner flotation of dolomite from phosphate.

Molecular dynamics simulation of magnesite and dolomite in

Flotation experiments Single mineral flotation tests for magnesite and dolomite were conducted in a 70 mL vertical flotation unit with PCP as the collector. For each test the mineral samples one gram 75 × 150 μm pH modifier and collector were added in turn to the flotation unit over a 2 min interval.

Evaluation of Dolomite Separation Techniques

Current tests included a final silica flotation stage whereas the reported testwork omitted this processing step. Feed size processed was 35/150 mesh. 4 UA Process – Reported to have failed to float dolomite or phosphate as designed when Bartow tap water was used during processing. Current testwork confirmed this reported result.

Investigation on flotation separation of bastnaesite from

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

dolomite extraction process

project report for magnesium extraction from dolomite. Mgo Extraction From Dolomite The dissolution of dolomite in hydrochloric acid was studied with the aid of a rotating disk system At 25 C the dissolution process is surface reaction rate limited even at low disk rotation speeds.

Selective reverse flotation of apatite from dolomite in

Reverse flotation is an effective method for obtaining apatite concentrates by floating dolomite from phosphate ore Abouzeid 2008 Sis and Chander 2003a . The most widely used collectors for the flotation separation of apatite from dolomite are conventional fatty acids.
