Multi-step flotation increased the purity of recovered fractions. The optimized process for a black mass < 250 µm, involving sonication pre-treatment and double flotation, resulted in enriched carbonaceous material (80.3 mol%) in froth fractions and high LFP concentration (81.9 mol%) in tailings fractions.

If required by the ash composition, froth flotation is a well-established technique that can be effective for separating carbon char from fly ash. Froth flotation is used for processing many types of ores, including cleaning coal fines (Harris & Wheelock, 2008). The process is based on differences in the "wettability" of materials.

Chalcopyrite and pyrite show recovery of over 90% when working with SBX and MIBC at pH 4–10. An increase in pH to 11.5 allowed lowering the pyrite recovery to 63%. However, when using PCA, pyrite flotation was significantly reduced at pH 4–8, while chalcopyrite was slightly affected, with recoveries over 90%.

Froth flotation works best when minerals are in an intermediate particle size range, typically from 20 to 150 μm, but varies with the types of minerals [[10], [11], [12]]. When particles are smaller than about 20 μm, value mineral recovery and separation selectivity drop quickly. This is because fine particles lack inertia and momentum, when ...
