Description. Outotec SkimAir is our leading-edge solution for flash flotation and flash roughing. It enables you to minimize overgrinding and improve overall mill throughput, recovery and dewatering. The SkimAir unit also provides help with achieving a more stable feed and better overall plant recovery. - Minimized overgrinding - Improved overall recovery - Increased mill throughput - Improved dewatering Outotec SkimAir is a flotation cell designed to be installed in a flash flotation
Apr 14, 2016 The concentrate produced in the Skim-Air is normally sent as final concentrate. Because only quick floating mineral particles have time to float in the Skim-Air, the concentrate from the machine is usually higher grade than that produced from the conventional flotation circuit. The higher feed density allows coarser particles to be floated resulting in an overall coarser concentrate being produced in the Skim-Air
Nov 01, 2013 The Skim Air flash flotation cell was developed by Outokumpu (now Outotec) in the early 1980s to be used ahead of conventional flotation in grinding mill circulating loads in order to “flash off” fast floating and liberated minerals of high value ( Coleman, 2010) and
Outotec is the provider of the Skim Air flash flotation cell which is the industry standard. We've got lab test procedures for evaluation for Greenfield cases and for retrofits - the procedures are quiet different to conventional flotation tests as there are a number of tricks involved to ensure that the results can be used for prediction of flash performance
their Micro-bubble Flotation (MBF) technology on gravity skim tanks. In this system, micro-bubbles are generated using one of two devices, either a unique pump or a patented pressure vessel design, and injected to the tank where intimate bubble and oil contact can occur. Due to the small size of bubbles (~30 microns), oil readily
GTK also has a 70-litre Skim-Air machine for coarse flotation, a SIF coarse flotation cell (300 litres), and several different types of flotation columns with volumes varying from a
Jul 01, 1994 FLOTATION CELLS AND CIRCUITS The most interesting and important application of new flotation cells for gold flotation is the Skim Air [Flash] flotation cells especially in a flotation plant where the tailings are not cyanide leached (e.g. 846 c.T
the cell volume. These bubbles lift contaminants to the liquid surface, forming a froth layer that is then skimmed from the liquid surface by a simple collection trough. Gas and a small volume of treated water are continuously recycled from the degassing chamber into the treatment cells. The skim cycles are automatically initiated by a timer
A DAF (Dissolved Air Flotation) system creates microscopic air bubbles that are attached to incoming wastewater particles in order to float them. Once floated, they are separated from the wastewater and skimmed from the top and into the float scum chamber. The treated wastewater then exits from near the bottom of the DAF
Jul 01, 1996 Flash flotation in Outokumpu Skim-Air[R] cells continues to be a widely used method of recovering coarse and easily over-ground particles from cyclone underflow in grinding circuits. The SK-1200 model has recently been introduced, capable of handling grinding circuit throughput in the range of 1,500 t/h in a single unit, thereby expanding

Jul 01, 1994 Flotation recoveries of free gold have improved dramatically with the installation of the Skim Air flotation cells in the grinding circuit [85,86,87]. Some modifications have had to be made to circuits where viscosity is a problem. Reagent additions are relatively low and the flotation rates fast. Froth level control is important because froth
no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator

A centrifugal pump (8) recirculates the clean water through a header to an eductor (9) in each flotation cell. Recirculation rate is 50%-125% of the total throughput. The ESI’s Quadair IGF can be equipped with one (1) recirculation pump or with an additional standby pump.. A gas blanket (10) (1-2 oz/sq2) is maintained above the water level to help saturate the liquid
The Metso Outotec LevelSense is designed for Metso Outotec TankCell flotation cells, but can be used with other types of cells too. Measurement is carried out by using a probe sensor system that is mounted on top of a flotation cell to penetrate the froth and slurry phases of the cell

Nov 19, 2019 SkimAir flash flotation project at Olimpiada . The SkimAir flash flotation project commenced at Olimpiada in Autumn 2014 with pilot and laboratory-scale test work. The first trial was conducted at the Olimpiada ZIF-3 concentrator (ZIF is a Russian acronym for gold recovery concentrator). This concentrator has 3mm gravity circuit pre-screen
The flotation cells which are predominantly used in commercial plants are of the mechanical aeration type in which gas bubbles and particles are brought together by vigorous agitation in a stirred tank. Air is introduced to the region of the impeller through the hollow shaft tank. ... In many prior art cells efforts have been made to skim off
The invention provides an agitator ( 1 ) is disposed to agitate slurry within a flotation tank ( 2 ). The agitator includes a rotor ( 6 ) mounted on one end of a centrally disposed drive shaft ( 7 ) extending axially downwardly into the tank and driven by a motor ( 8 ) and associated gearbox (not shown). The other end of the drive shaft includes a mounting flange ( 9 ) adapted for connection
