Reagents in iron ores flotation - ScienceDirect
The role of reagents utilised in iron ores flotation is reviewed. Desliming and flotation stages should be performed at pH levels as low as possible to reduce the expenses with caustic soda. Ether amines are by far the mostly utilised class of collector. The degree of neutralisation of the ether amine is an important process parameter.

Iron ore flotation process and reagents iron ore flotation process and reagents 173 viewshe keel is the professional mining equipments manufacturer in the worldn a process for the removal of phosphorous from, and for the production of, iron ore concentrates by flotation, in which crushed crude iron ore is mixed with water and a collecto.
Flotation Reagents - Mineral Processing & Metallurgy
The flotation reagents can be added in a feed-forward fashion based on the plant raw coal tonnage. Automatic feedback control of the flotation reagent addition rates has been lacking due to the unavailability of sensors for determining the quality of the froth cell tailings. Expensive nuclear-based sensors have been tried with limited success.
Froth Flotation of Iron Ores
The reagents used in iron ore flotation, including starch, amines and fatty acids, and the mechanisms of their interactions with the minerals in iron ore are examined. The presence of some specific impurities other than quartz in iron ore, such as alumina containing minerals, i.e. kaolinite and gibbsite, and phosphorous, is detrimental and attracts penalties.
Froth flotation - Wikipedia
Simple flotation circuit for mineral concentration. Numbered triangles show direction of stream flow. Various flotation reagents are added to a mixture of ore and water (called pulp) in a conditioning tank. The flow rate and tank size are designed to give the minerals enough time to be activated.
