BioteQ increases treatment capacity at Raglan mine, completes Caribou commissioning

BioteQ Environmental Technologies reports that its plant at Falconbridge's Raglan mine in northern Quebec has successfully increased production by 20% to reach a treatment capacity of approximately 550,000 cubic metres per year. The plant now has the capacity to treat between 140 and 150 cubic metres (m3) of water per hour, up from the previous production level of 120 to 125 m3 per hour.

The increase in production is the result of modifications the company has made to the water feed system to the plant. This is the first stage of a number of planned changes to the plant this year, which will result in further production increases. During the ramp-up in production the treated water quality has remained below 0.1 parts per million (ppm) nickel content, surpassing the target treatment objective of 0.5 ppm.

The Raglan water treatment plant is a unique nickel treatment process to selectively recover nickel from low-grade wastewater. The treated water quality produced in the BioteQ plant can be released directly into a pristine environment, such as the Canadian Arctic, and does not produce any by-product sludge for long term storage. BioteQ is paid monthly treatment fees based on the quantity of water treated.

Developed between 2001 and 2003 for the Raglan site, the process can be applied to other nickel-bearing waste streams. Patent application is in progress for the BioteQ technology.

In other activities, BioteQ recently announced the successful commissioning of a new tailings recovery plant at the Caribou mine site in New Brunswick. So far, approximately 15,000 tonnes of tailings have been treated. The commissioning began in June and the plant is operating at a design capacity of 12,000 tonnes per month. BioteQ expects to treat a total of 50,000 tonnes by the end of the year. Its capital investment of $210,000 should be recovered within a short time, as CanZinco, the owner of the Caribou site, has agreed to an annual treatment fee of $165,000.

The Caribou tailings recovery plant is a new operation for BioteQ and will give the company further operating expertise which it can apply to other sites in combination with its patented BioSulphide(r) process for metal recovery. This will enable BioteQ to offer a full range of tailings and water treatment services, combined with metal recovery.
