TAILINGS RECOVERY SYSTEM (TRS)

The Tailings Recovery System (TRS) is a technology developed specifically for recovering tailings from mine tailings pond deposits, to facilitate tailings pond reclaim operaons and management of tailings storage facilies within an operang mine site. TRS can also be ulized for the remediaon of legacy tailings ponds, and reprocessing mine tailings to extract valuable minerals.

TRS has been developed by Technika Engineering Ltd., a company based in Calgary, AB, Canada.

TRS effecvely addresses the operang limitaons of the technologies tradionally ulized for mine tailings reclaim operaons, including CSD dredges and submersible pumps. The limitaons of these technologies include inconsistent tailings supply density and the need for frequent relocaon on the pond. Dredging causes high turbidity of the pond surface water, which is oen reclaimed for the process requirements. Dredges and pumps are suscepble to plugging by various debris that is commonly found in tailings deposits.

Dredging is a crewed operaon requiring people to be deployed on the pond, and may also be affected by seasonal weather condions.

TRS technology is an unmanned, remotely controlled operaon. Its control can be effecvely integrated into the overall control system of the tailings treatment facilies, which enables the supply of tailings at a density and flow rate that is opmum for the performance of the tailings treatment processes.

TRS can operate from a single locaon for an extended period of me without a need to relocate.

TRS operaon is based on a balance of parameters that include its geometry, tailings rheology and recovery rate. The operaon of the technology is based on the principles of the hydraulic pressure balance within the tailings pond deposits and the TRS caisson structure. The operang interface between TRS and tailings deposits effecvely mobilizes the tailings within the pond deposits creang the tailings draw zone. The mobilized tailings are brought to the surface within the TRS caisson envelope.

The tailings of the required density are accessible from the surface for collecng and transport to the shore-based facilies.

The TRS caisson typically comprises two telescoping shells that allow easy adjustment of the pumping depth. The telescoping shells can be elevated to facilitate the system's launching, deployment, and relocaon.

The TRS assembly is of a modular design. The modules, which are designed to fit shipping envelopes, facilitate transportaon and minimize me to assemble the system onsite. This also enables easy relocaons between different tailings ponds or the mine sites.

An inial set of TRS units was developed by the Technika Engineering team and successfully deployed in large-scale tailings recovery operaons in the Canadian oil sands industry

The Company is now looking for opportunies to expand into other mining areas where the TRS technology can provide a valuable contribuon to mine tailings reclaim and tailings management operaons.

The TRS technology is patented and proprietary to Technika Engineering Ltd. For addional informaon, please visit hps://wwwtechnikaeng.com/technology/tailings-recoverysystem-trs.html contact@technika-eng.com
