Physical and chemical interactions in coal flotation

29/09/2003 Conventional froth flotation for fine coal cleaning suffers mainly from two problems: (i) a lack of selectivity for fast floating high rank coals due to the flotation of middlings and entrainment of mineral fines in the froth, and (ii) low recoveries for heavily oxidized or low rank coals due to poor adhesion between bubbles and particles. These shortcomings can be

Effect of microemulsified collector on froth flotation of coal

Kinetics of Coal Flotation

10/08/2018 Froth flotation is considered to be one of the effective physical cleaning technologies available to separate fine mineral particles from coal. Traditionally, the effectiveness of coal flotation has been evaluated based on yield and product ash and sulfur. However, understanding the flotation kinetic behavior of coal, ash and pyrite is important in order to simulate and optimize flotation

This difference could be probably due to the presence of pyrite which might have been depressed at Ph9. These results support the medium- coking characteristic of the coal deposit. Keywords:
