Up-scaling of froth flotation equipment

2015-8-31  cells in Boliden’s Aitik copper mine in Northern Sweden. The use of high volume flotation cells has nowadays become more and more common to deal with the production of high capacity, low-grade open pit mines, which are typically copper or gold mines.

New directions in flotation machine design ScienceDirect

2010-10-1  A new cell has been developed, the Concorde Cell, in which the pre-aerated feed is raised to supersonic velocities before passing into a high-shear zone in the flotation cell. The local dissipation rate is of the order of 100 kW/m 3,one to two orders of magnitude higher than is available in conventional mechanical cells.

Nano-microbubble flotation of fine and ultrafine

2014-7-1  1. Introduction. Froth flotation process separates solid particles based on the differences in physical and surface chemistry properties. It is the most efficient and cost effective for particles within a narrow size range, nominally from 10 to 100 μm for the minerals,.The lower and upper particle size limits are due to the low probability of collision and high probability of detachment

Analysis of key mixing parameters in industrial Wemco

2018-7-1  Abstract. Flotation performance in mechanical cells is strongly influenced by hydrodynamics. Hydrodynamics is driven by the action of the impeller which is responsible for mixing in the cell. This paper evaluates key mixing parameters in three industrial Wemco mechanical flotation cells (#144, #164, #190; 14.2, 28.3, 42.5 m 3 ).

Direct measurement of entrainment in large flotation cells

2009-1-25  A key response variable to describe the metallurgical performance in a flotation cell is the concentrate grade. The mineral feed characteristics and conditioning determine the grade of the particles attached directly to the surfaces of the bubbles by true flotation, while the operating conditions, such as gas rate, bubble size, froth depth and others, determine the amount of gangue recovered

CFD modelling of bubble–particle attachments in flotation

2006-5-1  The attachment rates from previous simulations in a laboratory flotation cell designed by CSIRO Minerals (Koh and Schwarz, 2003) are for bubble–particle attachments only, without the recovery of particles through the froth interface.In the previous work, the attached particles were removed from the pulp phase as soon as a bubble–particle aggregate was formed.

Effective harvesting of low surface-hydrophobicity

Microalgae harvesting by air flotation is a promising technology for large-scale production of biofuel, feed and nutraceuticals from algae. With an adherence-to-hydrocarbon method and two different types of flotation cells (mechanically agitated cell and Jameson cell), microalgal surface hydrophobicity and bubble size were identified to be critical for effective froth flotation of microalgae.
