Cementing operations can be divided into two broad categories: primary cementing and remedial cementing. The objective of primary cementing is to provide zonal isolation.
Flash Floc Mixing Systems precede Clarifiers and DAF systems.They are the chemical enhancement system that makes good treatment results possible.
Research interests include mineral processing and coal preparation, particularly phenomena involved in flotation separations including surface chemistry, particle/particle interaction and particle/bubble interaction.
hence reverse flotation can be employed rather than direct flotation wherein major proportion of the material,otherwise, would have to be floated. As such,the reverse flotation is the usual process for the beneficiation of iron ore slimes. Amines are the only cationic collectors used by industries in reverse flotation of iron ores.

ABSTRACT. This paper presents the study results of Mn 2+ ion influence on reverse cationic flotation of iron ore at pH 10.5. A small influence was observed on all response variables evaluated: mass recovery, Fe metallurgical recovery, grade of Fe and SiO 2 in obtained concentrates for dosages of MnCl 2 from 600 g/ton.

Due to gradual depletion of high-grade iron ores, there is a need to investigate the treatment of low-grade iron ores. Current procedures are time and cost intensive. Batch laboratory scale reverse cationic flotation was employed to concentrate low-grade Fe ore, found in fluorspar tails in the form of hematite.
