FIG 1 - A bottom driven laboratory flotation cell supplied by Runge Engineering. A typical test involves washing an ore pulp sample into the laboratory cell. Make-up water is added to achieve the desired volume. The impeller is started and set to the desired speed.
The Jameson Cell is a high intensity flotation cell in which pulp and air are brought together in a co-current descending flow in a vertical tube called the downcomer. The pulp is introduced into the downcomer through a slurry lens orifice to produce a high velocity jet that generates violent mixing and fine bubble size.
In this work, the prediction and optimisation of copper flotation has been conducted in the rougher flotation circuit. The copper-recovery prediction involved the application of support vector machine (SVM), Gaussian process regression (GPR), multi-layer perceptron artificial neural network (ANN), linear regression (LR), and random …
Flotation. A. Gupta, D.S. Yan, in Mineral Processing Design and Operation, 2006 16.3 Flotation Circuits. Flotation is carried out as a continuous operation in a series or bank of cells. This increases the floating time, allowing ample opportunity for particle-bubble attachment to occur. The residence time of particles in the bank of cells range from 5 to …
Flotation machines can be classified into two main categories: mechanical and pneumatic. Each type has its advantages and disadvantages, depending on the specific application. 4.1 Mechanical Flotation Machines. Mechanical flotation machines, also known as conventional flotation machines, are the most common type used in industry.
