FLSmidth Flotation, Agglomeration and Filtering

FLSmidth is your one source for the world’s largest installed base of original equipment, offering enhanced performance, increased recoveries, lower energy consumption and proven reliability that is unmatched in the mining and minerals processing industry.

FLSmidth combines its experience in the global market for liquid / solid separation equipment with one of the world’s largest installed bases of original equipment, operating under well-known trademarks (Dorr-Oliver, EIMCO, Shriver, Pneumapress, Krebs, and WEMCO), synonymous with know-how, reliability and performance.

Mineral liquid / solid separation

Few other liquid / solid separation technology suppliers can offer such a broad range of equipment and processes for industrial and environmental applications. This includes vacuum and pressure filtration, mineral flotation, clarification, classification, and thickening equipment, along with OEM quality replacement parts and modernization services.

FLSmidth has over 125 years’ experience and has successfully carried out a number of minerals-related company acquisitions over the past 16 years to continually complement its valued expertise and knowledge, and add to its repertoire of product offerings.

Flotation cells

FLSmidth has long been a pioneer of flotation and is the only supplier that can offer its clients three different technologies: WEMCO®, DORR-OLIVER®, and XCELL™. These three options mean you have greater control over a variety of particle feeds for maximum recovery.

SuperCells™ are large volume flotation cells starting at a 300m³ capacity and are designed around a universal tank. This creates greater flexibility because the tank can accommodate self-aspirated WEMCO mechanisms, or forced-air DORR-OLIVER or XCELL mechanisms.

Flotation cells for mines

Two SuperCells are currently operating at the Rio Tinto’s Copperton copper concentrator in Utah. FLSmidth is currently installing 26 of the WEMCO 300m™ SuperCells for Antofagasta Mineral’s Esperanza plant in Chile, which will be the largest installation of its kind in the world.

FLSmidth continues testing to analyse the differences and benefits of each of the WEMCO, XCell and Dorr-Oliver mechanisms to enable continual improvement on-site and for use in recovery evaluations for other installations. Previous testing has allowed FLSmidth to offer better optimization alternatives in rougher and cleaner stage applications and in both fine and coarse particle recovery.

Sedimentation – thickeners

FLSmidth’s line of Dorr-Oliver and EIMCO sedimentation thickener and clarifier units employ principles of gravity settling and range in sizes from pilot models to as much as 600ft in diameter. They can be used in a variety of industrial applications such as mineral concentrates and tailings, pulp mill wastes, iron and steel mills, and in cement, alumina and chemical plants.

Bridge-supported thickeners

FLSmidth offers bridge-supported thickeners, which are beam or truss-supported units that can be used with light, medium, or heavy-duty applications with diameters available for basins from 2m to 54m. The drive is supported by the bridge and drives the rakes with a center shaft. Underflow is removed from a discharge cone at the bottom-center of the thickener.

Column-supported thickeners

FLSmidth provides column-supported thickeners, supported by a stationary center column of steel or concrete. The center column supports the drive and rake mechanisms, while the truss extending from the center pier to the tank periphery supports the walkway, power lines and feed launder. These units are suitable for basins and raking arms with diameters of up to 600ft (180m). Choice of drive mechanisms and feedwells are available for all our thickeners.

Hi-rate thickeners

Hi-rate thickeners feature patented P-Duc, E-Duc, Dynafloc or Dynacharge feed and flocculation systems in combination with an energy dissipating, deep feedwell to maximize solids settling flux and clarity over conventional thickeners, in a smaller unit area. Raking mechanisms incorporate low drag, high raking efficiency designs to minimize torque at the higher loading rates.

Paste thickening technology for mines

Our paste thickening technology is key to successful tails stacking, mine back-filling, counter-current decantation (CCD) and maximum water and chemical recovery. EIMCO Deep-Cone® paste thickeners deliver thick underflow that approaches the limit of flow ability. They accommodate up to 20 times the solid mass flow and ten times the hydraulic loading of conventional thickeners and out-perform hi-rate and compression type thickeners in producing consistently higher underflow density.

The Dorr-Oliver paste production storage mechanism (PPSM) is a unique device and process designed to "flash thicken" solids to paste consistency, achieving a density between that of a conventional thickener and a filter. The paste viscosity is controlled to permit storage.

Mine clarifier thickeners

EIMCO E-CAT clarifier thickeners provide an innovative patented settling system that packs a liquid-solid separation flowsheet into one vessel. This system consumes a minimum of energy, requires little capital expenditure, and negligible operator attention. The revolutionary E-CAT contains no moving parts and combines optimized flocculation, hi-rate clarification and hi-density thickening in a single compact, rakeless unit.

Vacuum and pressure filters

FLSmidth has manufactured pressure and vacuum filters since 1910. Today FLSmidth offers filtration equipment for minerals processing flowsheets used for concurrent and countercurrent cake formation, cake discharge, washing, dewatering, settling, and drying.

FLSmidth pressure filtration products include a variety of Pneumapress automatic pressure filters, AFP filter presses, Shriver filter presses, Kelly Filters-vertical pressure filters, EIMCO beltpress filters, gravity belt thickeners, Dregs ClariPress filters, white liquor ClariDisc filters, and pressure tube filters.

Vacuum filtration products include horizontal belt filters, vacuum drum filters, vacuum disc filters, horizontal pan filters, pre-coat filters and indexing belt filters.

Metallurgical testing

Since 2008, FLSmidth has been able to offer metallurgical testing services through its acquisition of Dawson Metallurgical Laboratories. Dawson has valued experience in precious metals, base metals and industrial minerals, and now provides testing services.

Customer services

FLSmidth offers worldwide sourcing, process testing, flowsheet development, custom equipment engineering, innovative design, manufacturing, construction, start-up, rebuild services, replacement parts, OEM parts, filter media replacement and system modernizations.
