Effects of Different Flotation Agents on the Nucleation and Growth of Potassium Chloride

open access: yesMolecules, 2023
The flotation agent is an important collector in the production of potassium chloride and is brought into the crystallization stage with the reflux of the mother liquor.

Particle size grouping method as a control system of efficiency flotation process on the example of coal [PDF]

open access: yesJournal of Mining and Metallurgy. Section B: Metallurgy, 2021
Agglomeration of coal particles during flotation can be analysed with the Particle Size Grouping (PSG) method. Numerous experiments were carried out to theoretically explain the effect of carbon particles agglomeration, but the result still remains ...

Research progress on the impact of mineral surface roughness on particle-bubble interaction

open access: yesMeitan xuebao, 2023
Mineral surface roughness is an important factor affecting flotation efficiency. Surface roughness can affect the hydrophobicity of minerals, the adsorption of reagents, and the rupture of liquid films between particles and bubbles, resulting in a ...

Effect of carbon equivalent on graphite formation in heavy-section ductile iron parts [PDF]

open access: yes, 2010
The influence of post-inoculation and of cerium and antimony additions on the solidification process and on the formation of chunky graphite in ductile iron heavy-section parts have been studied previously in the case of near-eutectic alloys. It appeared

Application of Thionocarbamates in Copper Slag Flotation

open access: yesMetals, 2022
Thionocarbamates are the group of collectors that are mostly used for flotation of sulphide copper minerals, alone or in combination with xanthates depending on a mineralogical composition of the ore.
