On-line Colour Measurement of Flotation Froth
This paper reports new results regarding the usefulness of colour measurements in flotation process. Colour measurements coming simultaneously from RGB-camera and a spectrophotometer (and from the same measurement point) are compared. The measured variables are used to construct a partial least squares (PLS) model and a multilinear regression (MLR) model for the prediction of the zinc content i...
متن کاملFroth flotation of phosphate rock
The development of froth flotation is traced from its earliest-known use through the discoveries leading to the present knowledge of the science. The factors influencing the flotation of non-sulfide and non-metallic minerals are discussed, and the machines used in commercial flotation operations are described. Experimental work on the flotation beneficiation of phosphate rock is presented as an...
متن کاملHarvesting of algae by froth flotation.
A highly efficient froth flotation procedure has been developed for harvesting algae from dilute suspensions. The method does not depend upon the addition of flotants. Harvesting is carried out in a long column containing the feed solution which is aerated from below. A stable column of foam is produced and harvested from a side arm near the top of the column. The cell concentration of the harv...
متن کاملConcentration of bauxite fines via froth flotation (
Companhia Brasileira de Alumínio (CBA) has bauxite processing plants at Poços de Caldas and Itamarati de Minas, and a new processing plant at Miraí that has been operating since June, 2008; all of them are in the State of Minas Gerais. The plants haveunits for the crushing, scrubbing and screening operations. The screened oversize is the concentrate or washed bauxite. At Itamarati de Minas, the...
متن کاملEstimation of Air Fraction Profiles in the Stabilized Froth and Froth Regions of a Flotation Column Using Conductivity Probes
In the collection zone of a flotation column, the air holdup is known to be relatively constant along the column height. The effect of the decrease in hydrostatic pressure with height may need to be taken into consideration, particularly for tall industrial columns. However, this phenomenon is readily ascertained. On the other hand, the changes at the pulp-froth interface, as well as the air fr...
