Characterization and Flotation of Sulfur from Chalcopyrite

The majority of chalcopyrite remains in the sulfur flotation tailings and can be readily recovered by flotation with different flotation reagents. When amyl xanthate is used, 85% of chalcopyrite can be recovered with a copper grade of 14.5% in a single stage froth flotation. The chalcopyrite flotation concentrate can be sent back to chloride

Characterization and Flotation of Sulfur from Chalcopyrite

2016 7 13   The sulfur particles tend to agglomerate in the pulp and hence mechanically entrap gangue minerals. With sodium silicate as the dispersant as well as the depressant for siliceous material, a sulfur concentrate of 90% in grade and 90% in recovery can be obtained with a single stage froth flotation. The flotation reagent consumptions are minimum.

Moving Horizon Estimation of Sulfur Concentrate Grade

This article proposed a moving horizon approach to predict sulfur concentrate grade in a sulfur flotation process. In this approach, the grade prediction problem is formulated as a moving horizon estimation problem. To build the nominal model for the estimation, the kinetic of sulfur flotation process are firstly studied. The unknown variable in the kinetic model, i.e., the flux of
