A pilot-scale version of the modified Jameson Cell has been used in the spodumene flotation of dressing plant of Ganzi Rongda lithium Co., Ltd. and the flow-sheet was depicted in Fig. 2. The ore was ground to 60% passing 74 μm using one stage of grinding (ball mill). The head grade was about 1.29% Li 2 O.

The column flotation cell (CFC) was invented in the 1960s but did not gain wide acceptance in the processing of base metals until the early 1980s . In column flotation, ore is introduced near the top of the column and sparging air from bottom, creating a deep froth zone. Wash water is added from the top to remove fine entrained …

The RFC has been successful in treating feed materials ranging from ultra fine (<45micron) to coarser particle size distributions up to 2mm. Can the RFC be retrofitted to my existing flotation cells? The unique nature of the design and use of the lamella plates means this isn't something you can retrofit onto existing flotation cells.

Flotation is a method that enables the separation of hydrophobic particles with the help of air bubbles (Fig. 3 a). In flotation, the particles adhere to air bubbles depending on solid, liquid, and gas contact phases. The interaction of particles and bubbles includes collision, adhesion, and stability [ 3, 4, 5 ].
