Hence, in scenarios where the contents of quartz in phosphate ores are high, cationic collectors, specifically amine collectors, are employed for the reverse flotation process for these phosphate ores, based on the aforementioned second characteristic of quartz surface, namely its strong electronegativity [20].

Currently reverse flotation is one of the most common industrial beneficiation methods for separating limonite from gangue minerals (Shrimali et al., 2018, Deng et al., 2021).In this process, the iron ore remains in the flotation tank as a non-floating fraction, while the silicate minerals float up to form a froth layer with the help of attached bubbles.

The flotation process is designed according to the existing impurities in the ore. Commonly, the presence of silicates and carbonates results in lower purity of natural phosphate rock sources. With Kao's chemistry, specific answers are available for each challenge in both the direct and reverse process.

Thus, upgrading process development was required for increasing the grade of the ores to meet the demand of the iron and steel industries. The beneficiation was studied extensively 2 – 4 which consists of several stages, and anionic reverse flotation was the common route in the processing plants to produce the final concentrate 5 – 9.

Flotation is one of the most effective technologies for the up-gradation of coal fines of particle size below 0.5 mm because of the inherent hydrophobic nature of coal. Contrary to this, reverse flotation of coal in which coal particles are depressed and gangue particles floated, was developed as an alternative process to minimise the sulphur content in the coal.

This study investigates the reverse flotation separation of chalcopyrite and talc using KMnO 4 as a depressant and DDA (dodecylamine) as a collector within a reverse flotation system. Single mineral flotation experiments show that after adding KMnO 4, the recovery of chalcopyrite in 38–74 μm is only 6.86 %, whereas the recovery of talc in ...

There are forward flotation and reverse flotation methods for separating spodumene from gangue minerals (Kundu et al., 2023). During forward spodumene flotation, the floating of spodumene is achieved using anionic or mixed collectors, while the gangue minerals are left behind in the tailings (Gibson et al., 2015; Xie et al., 2020).
