Introducing the Hawk Fines Recovery Plant
As part of EIW’s end-to-end washing equipment line, the Hawk Fines Recovery Plant captures fine particles down to 400 mesh (2.7 SG) from process water in aggregate waste streams. It produces drip-free, stackable solids that are easy to handle and reduces the volume of material sent to settling ponds.
The plant can operate as a standalone unit or serve as the first step in a larger tailings management system, integrating liquid-solid separation to improve fines recovery and reduce material loss.
The Hawk Fines Recovery Plant is built with a compact, modular design consisting of a Sump, Pump, Hydrocyclones and a Dewatering Screen. Instead of being sent directly to a settling pond, the waste stream enters the sump, where it is pumped to the Hydrocyclones. The Hydrocyclones separate coarse ultrafine solids from the process water, discharging them onto the Dewatering Screen, which removes excess moisture to produce a drip-free, conveyable product.
The majority of the water and some remaining fine particles exit through the Hydrocyclone overflow. The remining portion of this water is recirculated for sump level control or directed to a settling pond or additional downstream processing equipment.
By capturing coarse/larger fine solids before they reach the pond, the Hawk Fines Recovery Plant helps reduce pond maintenance frequency, lowers labor and equipment costs, and recovers material that can potentially be repurposed for applications such as pond lining or backfill material, creating an additional revenue source.
Hawk Fines Recovery Plant Features
The Hawk utilizes a compact, modular design for quick setup and a small footprint. The access walkways can be installed with left or right orientation and stairs can be placed in six locations to accommodate the needs of any site.
Hydrocylones
The Hawk utilizes Hydrocylones that feature a range of vortex finders and configurable apexes to separate ultra-fine particles from process water and directs them onto the Dewatering Screen. The Hawk 3000 uses three Hydrocyclones while the Hawk 6000 uses five. The Hydrocylones are fabricated from mild steel with rubber lining. The fabricated steel feed distributor is also rubber lined with five ports.
Dewatering Screen
The Hawk features a Dewatering Screen with two vibratory motors: 8.5 HP on the Hawk 3000 and 13 HP on the Hawk 6000. Polyurethane screen media is standard on the Dewatering Screen; however, configurable media is available to suit various duty applications. The Dewatering Screen also features a steel support structure with a walkway on one side and an access stairway.
Pump & Sump
The Hawk 3000 utilizes a 10” x 8” (25.4 cm x 20.3 cm) rubber-lined slurry Pump while a Hawk 6000 utilizes a 12” x 10” (30.5 cm x 25.4 cm) Pump. The Pump is designed with high wear resistance and adjustable speed settings. A rubber-lined discharge hose moves discharged material from the Pump to the Hydrocyclone feed manifold.
The flanged feed entry collection sump has a configurable feed orientation for left or right placement. It utilizes an electric on/off/modulating sump level control valve with a pressure transmitter.
The Hawk Fines Recovery Plant is an efficient solution for producers looking to improve material recovery, reduce waste and lower operational costs. By capturing valuable fine solids before they reach the settling pond, the Hawk helps to transform waste material into a revenue-building product. For operations focused on efficiency in water management, the Hawk Fines Recovery Plant can deliver measurable results.
