Machine vision based monitoring of an industrial flotation cell in an iron flotation plant

International Journal of Mineral Processing, 2014
Abstract Froth flotation is the most commonly used technique for the separation of valuable from gangue minerals. Unforeseeable changes in the ore characteristics and operating conditions have necessitated continuous control of the flotation circuits.

Application of New Flotation Machine on Phosphate Flotation

Advanced Materials Research, 2012
Phosphate is a typical oxide ore characterizing that generating abundant froth during flotation. In this research a new flotation machine was employed in the flotation of phosphate. Comparing to regular flotation machine, in the reverse flotation of dolomite the recovery and grade of MgO has no significance improvement.

Oscillations in a laboratory flotation machine

International Journal of Mineral Processing, 1984
Abstract In a laboratory Denver machine, worn impeller/stator assemblies lead to strong, rapid oscillations of the water level in the standpipe at impeller speeds just below self-aeration. Frequency depends linearly on impeller speed, decreasing with impeller depth. Amplitude passes through a maximum with speed, increasing with depth.

On the hydrodynamics of flotation machines

International Journal of Mineral Processing, 1978
Abstract Flotation is realized under highly turbulent flow conditions, so that turbulence may be process-determining, too. Because the principles of turbulent multi-phase flow have still not been fully worked out, one needs integral quantities to characterize the state of turbulence indirectly.

BGRIMM Mechanical Agitation Flotation Machine

2021
The mechanical agitation flotation machine is one of the flotation machines that is invented at the earliest. The early mechanical agitation flotation machine is designed with a complicated structure, but a poor flotation effect. With the development of science and technology and the gradual revealing of the principle of flotation, the performance of ...

Flotation Machine Upsizing Method and Technology

2021
With the social development, there has been increasing demand for mineral resources, and mineral resources have gradually become poor and complex due to the continuous development. It is necessary to improve the processing capacity of flotation equipment greatly in order to process more and more poor ores and refractory ores.

Flotation machine design: impeller—stator interaction

Powder Technology, 1985
Abstract The separate contributions of impellers and stators to suction are studied by means of interaction models. From these, suction can be predicted when interchangeable components are used in any combination, and in either direction of impeller rotation. Methods are devised by which numerical values of the impeller and stator terms can be simply

A recycle flow flotation machine model

International Journal of Mineral Processing, 1975
Abstract Residence time measurements were made on a Denver laboratory flotation machine with and without the DR ring assembly. Soluble and insoluble tracers were used (a dye and fine quartz, respectively), and the variables studied were tank liquid volume, V , water and air volumetric flow rates, Q and QA respectively, and some geometric and ...
