Method of constructing a continuously operable flotation

I claim 1. A method of effecting flotation of mineral grains on a laboratory scale comprising conducting a mineral sample of uniform grain size and uniform mineral composition into water in a flotation cell, subjecting the mineral grains to conditioning by conducting a strongly adsorbable collecting agent into said water in an amount which is a fraction of the amount sufficient to create a ...

Flotation The Past Present and Future of Mineral

The StackCell, which is much smaller than a traditional flotation cell, can shrink the size of a flotation plant by 50%. The knock-on effect is that it also requires less concrete (smaller carbon footprint), less piping to connect the units, and fewer electrical connections and cable trays and pipe racks, thus reducing CAPEX and engineering ...

Unit processes of grinding, conditioning, and flotation were studied individually and in con cert, and a series of continuous tests were run based on the parameters developed to obtain engineering data for subsequent economic analysis. Overall cobalt grades of 3.00

Continuous cultivation and flotation of Hansenula

Abstract In a 300-1 stirred tank reactor provided with a foam separator, Hansenula polymorpha and Saccharomyces cerevisiae were cultivated continuously in the absence of antifoam agents, and the cells were recovered continuously from the cultivation medium in a flotation column, 3.6 m high, 10 cm inner diameter, which was directly connected to the reactor.

through the flotation cell, where it is saturated with gas. It is then sent to a flotation vat, where the deposits, combined with the gas, are suctioned or scraped off the surface, depending on their viscosity. The clear must is then collected continuously. Batch flotation Batch flotation is based on the same principle as continuous flotation ...

Effect of Froth Structure and Mobility on Plant

Apr 06, 2007 The structure of froths (and associated drainage patterns) developed on a continuously operated flotation cell over a wide range of operating conditions is reported. The concept of shear induced drainage in the froth is introduced, where mobility in froths on producing cells is seen to reduce froth separation effects.

TECHNICAL NOTES 9 FLOTATION

Almost all successful models of the flotation process have been based on the premise that flotation is a kinetic process. In this way a model can be formulated in terms of a rate of flotation which can be quantified in terms of some of the many chemical and physical factors that define the environment inside a flotation cell.
