Flotation Machine Upsizing Method and Technology
Flotation is a complex physicochemical reaction process involving the three phases of gas, liquid and solid. The scale-up process of the flotation machine does not mean to increase geometric dimensions of key components (such as the tank cell, rotor and stator) of the flotation machine simply in proportion, but it requires the full consideration …

The Inspiration Copper Co. uses flotation as the prime process, and its 800 tons per section is treated by 24 roughing-cells and 4 cleaners. In this case the cells are run in series, the primary cells treating the original feed and the secondary cells re-treating only the slime from the primary tailing after the sand has been removed.

Minerals | Free Full-Text | On Limits to Flotation Cell Size
Mechanical cells have seen an exponential increase in size over the past 60 years. However, a possible size limitation due to carrying capacity constraints has been raised. Taking a Cu porphyry case, a cell sizing exercise is used to show that possible size limitation due to carrying capacity can be tested using available techniques. A range of …

The overall objective of the proposed work is to investigate the effects of different flotation cell height to diameter ratios in order to identify optimal aspect ratios for flotation cells when sizing new flotation circuits, but also for the optimisation of existing plants. In this ...
Flotation
Flotation is an extremely size sensitive process and because the RC drilling process imparts a lot of energy into the sample, the resulting fine particle size distribution is likely to be much finer than required. Also, the detergents used in RC drilling will very often react unfavorably in the flotation cell with other reagents.

New approach for flotation process modelling and simulation
More recently, the cell sizes have reached values up to 500, 630 and 660 m 3 (Grau et al., 2014, Lelinski et al., 2017, Grau et al., 2018) which poses a greater relevance on the impact the froth has on the overall flotation process. The larger amounts of collected minerals that overflow into the concentrate launders increases proportionally to ...

The sizing equation is as follows: N·Vcell = F × T × E × P. 2 (1) where F is the dry solids feed rate (t/h), T is the plant retention time (h), E is the pulp expansion factor to allow for gas holdup (GH, assumed 15%), and P is the pulp volume. where per tonne F is of the solids dry (m3/t). solids Introducing feed rate (t/h), the values: T ...
DR flotation machines
In principle, the cell functions as a shallow flotation cell. As the air and pulp are hydrau-lically lifted to the top of the pulp recircula-tion well, the mineral laden air bubble has only to travel a short distance on its own to the froth overflow level. Above are illustrations of three flotation cells. 14.2 m3 (500 cu.ft) cell 2.8 m3 (100 cu ...
