Residence time distribution in large industrial flotation

Residence time distribution in large industrial flotation cells to measure the residence time distribution (RTD) of the liquid and solid in an industrial rougher flotation bank consisting of 7 cells of 130 m3. Thus, a pneumatic system of high reliability was used in order to introduce a small amount of radioactive tracer (around 100 mL of liquid or pulp) at the feed pulp entrance. Then

Optimizing flotation bank performance through froth depth

Flotation bank Optimization Genetic algorithms Mass-pull profiling abstract This communication revisits previously reported results on froth depth profiling along a rougher flotation bank. The optimization problem is reformulated as to maximize the overall bank Cu recovery subject to a lower bound constraint on the overall Cu concentrate grade. This formulation differs from that originally

AMIT 145: Lesson 5 Froth Flotation – Mining

Rougher banks can be large with the number of cells being 5 or greater. Scavenger cells are the last line of defense for avoiding losses. Therefore, they are generally larger in size and numbers. Cleaner banks are focused on product grade and thus provide low residence time. As such, the number of cells are lower and the cells smaller. Column flotation is sometimes used as cleaners. Recycle

Operation of rougher flotation circuits aided by

In this work, a procedure for modeling and simulation of rougher flotation banks, based on operating variables and parameters fitted from industrial data, is presented. This simulator is used to develop a set of logic rules in order to aid operating decisions. Recently, a new methodology for describing the industrial flotation, separating the collection and froth zones, has been developed

Pyrite recovery mechanisms in rougher

From top of froth grade measurements along the rougher bank, it was observed that a fraction of fine pyrite was also recovered by true flotation (top of froth grade increasing), considering that the solids in this class were more liberated. On the other hand, the coarse pyrite (+45 μm) was mainly recovered to the concentrate by true flotation or association with valuable minerals as indicated
