The Concorde Cell is a high intensity pneumatic flotation cell dedicated to fines and ultrafines Its development by Professor Graeme Jameson and later on by Metso was driven by two considerations a reduction in bubble size and an increase in the shear rate and energy dissipation rate increases the particle bubble collision and attachment efficiencies of fine
of superior quality flotation product at elevated recovery The RFC is a very high capacity efficient flotation technology capable of implementation in various applications Improved kinetics for fast high throughput flotation A new flotation cell that radically alters the perception of productivity 0
4 Fine particles require high intensity mixing while coarse particles prefer a low turbulence environment NovaCell accomplishes both in one unit Conventional flotation technologies for example mechanically agitated cells have a single recovery zone at the impeller for all particles he said
Flotation machines constitute the basic equipment for useful minerals recovery from non ferrous ores and other raw materials by flotation They can operate also as individual flotation cells Flotation Cells Froth Flotation were developed to separate and recover high value Sulphide ores from low grade ore bodies The Flotation Cell is aerated to produce bubbles and
cells and details of this design will be discussed later in this article The top section of the disc connects to a drive shaft which in turn connects to the pulley/gear motor drive assembly The impeller is located in the centre of the cell cross section with its II/FLOTATION/Flotation Cell Design Application of Fundamental Principles 1505
The Sub A Flotation cells technology has been around for a long time since the Denver Equipment Company first developed it in 1968 after inventing the flotation machine of 1940 and changed the mineral processing industry The SUB A float machines used in the mineral chemical environmental and industrial applications requiring the efficient dispersion

Froth flotation using a mechanical cell is the key beneficiation approach for high recovery mostly below 150 μm depending on the nature of the ore and below 70 μm for base metals Jameson 2010 Nguyen and Schulze 2003 ; however the recovery of coarser particles diminishes with increasing size of the particle due to high turbulence near

In recent decades the exponential increase in the cell volume of flotation cells has promoted significant advantages such as those related to investment costs footprints and energy savings
Flotation tests on the shaking table tails were conducted using a 2 L Denver cell For lead and silver rich ores the collector chosen is critical in the high grade recovery process of the flotation A selected pH of and the performance under evaluation of a number of collectors namely Z11 PAX DTP and SIPX are shown in Fig 6 Since
values are recovered at the back end of the circuit in the scavengers cleaners and high energy cells The work presented here investigates the use of reagents in improving flotation Figure Variation of a Grade Time and b Grade Recovery Relationships for Flotation of Scavenger Bank 3 Feed with 25g/t Depressant
Historically flotation cell volumes have grown exponentially with mechanical flotation cells now more than 600 m 3 in volume Govender et al 2014; Lelinski et al 2015; Shen et al 2019; Suhonen et al 2019; Yang et al 2019 These changes which provide improved economy of scale reflect the fact
The conical disk impellers and wearing plates have been used in Sub A Flotation Machines for many years but are rapidly being replaced by the receded disk impellers and diffusers for general purposes Conical disk impellers are recommended for Unit Flotation Cells and applications such as treatment of dense pulp and coarse material
Metso Outotec is launching groundbreaking Concorde Cell flotation technology for efficient fine and ultra fine particle recovery This innovative Planet Positive technology sets a new benchmark in high intensity pneumatic flotation reducing plant operation costs and contributing to sustainability of operations through minimized energy and water consumption
The impeller of BF type flotation cells is closed structure which resolve the technical problems of Radial reflux flow and axial slip flow making generating the high capacity of air absorption by the low impeller rotation speed up to the aim of energy saving which is conducive to recovery of coarse grained minerals in suspension 4 The
