Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.Minerals | Special Issue : Flotation Chemistry,The micro-flotation and Bench-scale flotation results further verify that TTPC presents a stronger collecting power and much better selectivity for iron ore reverse flotation in comparison to the conventional collector DTAC.

Froth flotation of iron ores - AMERICAN CYANAMID CO

From the point of view of susceptibility to froth flotation, this is particularly unfortunate since the iron minerals and these silica-bearing gangues are generally difficult to separate. Because of this separational difficulty, a flotation process to be successfully carried out requires careful handling, usually also accompanied by a high,Quality Prediction in Iron Ore | Kaggle,Silica Concentrate is the impurity in the iron ore which needs to be removed The current process of detecting silica takes many hours. With the help of some analysis and modelling of data we can give a good approximation of silica concentrate which will reduce a lot of time and effort required for processing iron,
