For reactor cell systems, Equation (1) has been used to determine the flotation cell volumes (V f) as a function of an estimated residence time (, 2006): (1) α V f = Q τ S where Q is the volumetric feed flowrate of pulp, τ represents the residence time of one machine, S denotes a scale-up factor (which depends on the source of the τ ...
In a flotation cell, the size of air bubbles decreases with increasing the frother concentration. This is due to a lowering of the interfacial (gas–liquid) tension and the stabilization of the thin liquid film formed between colliding air bubbles, hence preventing their coalescence (Grau and Laskowski, 2008, Khoshdast and Sam, 2011, Khoshdast et al., 2011).

The string of recent orders includes 12 BQR flotation cells for a fluorspar processing plant in Spain. Here, the cells are equipped with eDART internal dart valves for the larger cells and external pinch valves for the small cell. eDART valves are known globally for their superior and safe design, TAKRAF said.
At one mill treating approximately 200 tons of fluorspar ore per day, an 8-cell No. 21 rougher is used but they are adding another 2-cell No. 21 on the end as scavengers. They use a 10-cell No. 21 for cleaning 3 times (4-3-3 combination). They produce 100-120 tons per day of acid CaF2. Flotation feed into the roughers is approximately 35% solids.
Similarly, metspar concentrates assaying 90% CaF2, suitable for metallurgical applications, can be achieved in a single-stage cleaning by column flotation. This is an …
