DST Signs Contract for Delivery of Arsenic Vitrification Plant

  December 01, 2017

MONTREAL, QUEBEC, December 1, 2017 – Dundee Sustainable Technologies Inc. (“DST” or the “Corporation”) (CSE: DST) is pleased to announce that it has entered into an agreement (the “Agreement”) for the construction and operation of an onsite Industrial Scale Plant using a DST’s proprietary arsenic stabilization technology (the “DST Technology”).

The plant, to be funded by the customer, will be constructed in Thetford Mines and delivered to the customer’s metal processing facility (the “Facility”) in 2018 where it will begin a 12-month operation period. The plant will have a design capacity of 8 tonnes per day of glass which will contain up to 20% arsenic.

The objective of the Agreement is to confirm, at the industrial scale, the amenability of the DST Technology for the treatment of flue dusts produced by the Facility. Following the 12-month operation campaign, a study will be performed to evaluate the technical and economic implications of a full-scale DST arsenic vitrification plant to be located at the Facility.

This Agreement is another major milestone in DST's efforts to confirm the viability of the arsenic stabilization technology on an industrial scale. DST will continue to advance discussions with customers and strategic partners towards developing the feasibility criteria for the commercial implementation of the DST process.

DST’s process uses lower cost inputs to economically produce a more stable product than current industrial practices. Innovative options to stabilize arsenic is becoming an attractive technique to segregate the arsenic and is applicable for deposits or concentrates considered to contain arsenic concentrations to high to be exploited using conventional approaches. The resulting glass is non-toxic and meets or exceeds the United States Environmental Protection Agency's (EPA) toxicity characterization leaching procedure (TCLP, Method 1311).
