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 …

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.

The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is …
