BioteQ treatment plant approved at Raglan mine
BioteQ reports that its water treatment plant at the Raglan mine in Quebec is fully operational, with treated water meeting both plant design criteria and regulated discharge limits. The plant began treating water in June in a closed loop, with no discharge to the environment. The 30,000 cubic metres of treated water it produced during July met the Quebec Ministry of Environment's stringent water quality discharge regulations. Consequently, the Ministry issued a certificate of authorization for discharge to the environment on August 16th, allowing BioteQ to discharge the treated water to the environment.
The nickel product recovered in the plant is owned by Falconbridge, owner and operator of the Raglan mine. The facility was designed to yield a nickel product containing a minimum of 20% solids, for addition to the primary nickel production at Raglan. The current operating density of the nickel product is over 30% solids. BioteQ receives monthly payments from Falconbridge consisting of a fixed capital fee, which began in late 2003, plus a fee for water treated of $1.06 (Cdn) per cubic metre.
Plant start-up began on June 16 when water was available for pumping from under the ice. During late June and early July, the company notes that plant performance improved rapidly with nickel recovery surpassing 99% in July.
Since mid-July the plant has been operating at or below the regulated discharge limit of 0.5 mg/L total nickel (monthly average), up to the latest reporting period of August 19. The facility permit allows a daily maximum limit of 1.0 mg/L total nickel.
Based on the rapid startup and treatment plant capacity, it is expected that the plant will meet the treatment target for this year if the operating season extends to the end of November, as was the case last year. BioteQ's target for 2004 is 530,000 cubic metres of water treated.
Focused on the mining industry, Vancouver-based BioteQ has teamed with multi-national metal producers such as Falconbridge and Phelps Dodge to design, build and operate water treatment plants. Its patented BioSulphide(r) water treatment process recovers saleable metals, generating income for the plant owner while meeting new, stricter environmental regulations.
