The flotation experiments were performed by varying the flotation cell energy input parameters of volumetric air input flow rate and flotation cell rotor speed depending upon the experiment matrix. Level in the flotation cell was maintained using a 20-liter conditioning tank. Frother and pH modifiers were added into the conditioning tank.
For iron ore floatation, reverse flotation is generally preferred where siliceous minerals are floated and iron-bearing minerals are generally depressed. Flotation process is generally less cost-effective and more operationally challenging than the magnetic separation process.
The beneficiation of low-grade iron ores is a key research and development topic in the mineral processing industry. The gradual exhaustion of high-grade iron ore reserves, and rising consumer iron and steel demand globally necessitate efficient low-quality iron ore beneficiation to meet steelmaking quality requirements. This …

Abstract— Mineral ore beneficiation and value addition has become a key factor for economic growth in Africa. Froth flotation process is used to concentrate relatively low grade ores.
The way to successfully upgrade a phosphate ore is based on the full understanding of its mineralogy, minerals surface properties, minerals distribution and liberation. The conception of a treatment process consists of choosing the proper operations with an adequate succession depending on the ore properties. Usually, froth flotation …
The mined graphite ore contains several gangue materials which needs to be removed through beneficiation. Ore beneficiation is a separation technique that enriches the desired mineral from their ores through systematic judicious removal of gangue materials that are undesirable.
Complex and non-sulfide lead–zinc ores are difficult to concentrate, but the growing demand for lead and zinc metals necessitated their beneficiation. Froth flotation is practically the most effective method in their beneficiation when optimum flotation conditions are attained. The aim of the current study is to use process mineralogy as a …
To meet the increasing demand for lithium, there is a need to optimize and improve its beneficiation and extraction from ores. Processing of lithium ore, like most minerals, begins with beneficiation prior to extraction of its compounds in …
