Therefore, it is necessary to improve the floatability of fine pentlandite (Musuku et al., 2016, Kojonen et al., 2008). The design of the turbulence generating system (the impeller-stator system) in a flotation cell can improve the recovery of fine particles by providing small bubbles and thus increasing the bubble-particle collision probability.

As shown in Table 2, the better results were obtained from modified Jameson Cell than traditional mechanical flotation machines in flotation of spodumene ore. When the content of LiO 2 in feed was 1.29%, the Li 2 O concentrate grade reached 4.60% with the recovery of 57.42% by modified Jameson Cell separation through a one rougher stage.

Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells, e.g., 0.03 m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance the …

Gold losses during flotation often occur within the fines fraction, which has been an ongoing issue that has challenged the gold mining industry. Subsequently, operations will attempt to coarsen up the primary grind to reduce the fine gold (free gold or sulphide gold) generation, resulting from over grinding. Under-grinding can then to lead to gold losses …

The research on the flotation dynamics of fine particles showed that the flotation rate constant is K ∝ d p /d b for fine particles (where d p and d b are the diameters of mineral particles and bubbles, respectively, n = 2, m = 2.67–3). Therefore, reduction of the bubble diameter is one of the main ways to improve the flotation of fine ...

Flotation of fine particle (<37 μm) and ultrafine particle (<8–13 μm) is a key challenge. Feed in flotation consists of wide range of particle size, therefore, flotation column needs to have wider bubble size to target fine as well as coarse size particles [13,14]. So, flotation of fine particles is one of the major challenging tasks.
