Dundee Sustainable Technologies Completes its Arsenic Stabilization Plant
Dundee Sustainable Technologies Completes its Arsenic Stabilization Plant
– Momentum Public Relations – Jan. 28, 2016
Dundee Sustainable Technologies Inc. (“DST” or the “Corporation”) (DST:CSE) is proud to announce that it has successfully achieved, as part of the commissioning of its newly constructed arsenic stabilization pilot plant, its first casting of arsenical glass, using DST’s proprietary technology. This technology is designed for the sequestration of arsenic in a stable glass form.
In December 2015, arsenical glass was smoothly casted from a stabilization trial run. The produced glass was submitted to the United States environmental protection agency’s (EPA) toxicity characterization leaching procedure (TCLP, Method 1311) and the non-toxicity of the arsenical glass was confirmed well below the norm.
DST’s process uses lower cost chemicals to economically produce a more stable product than current industrial practices. This process to stabilize arsenic is becoming an attractive technique to segregate the arsenic and is therefore opening new opportunities for remediation sites and for deposits or concentrates considered to contain too much arsenic to be exploited using conventional approaches.
The production of this glass is a major achievement in DST’s efforts to demonstrate the technical and economic viability of the arsenic stabilization technology on an industrial scale. DST will advance with strategic partners towards developing the technical and economic feasibility criteria for the implementation, on a commercial scale, of the DST process.
About Dundee Sustainable Technologies, a company controlled by Dundee Corporation
The Corporation is engaged in the development of environment-friendly technologies for the treatment of materials in the mining industry. Through the development of patented, proprietary processes, DST extracts precious and base metals from ores, concentrates and tailing, while stabilizing contaminants such as arsenic, which could not otherwise be extracted or stabilized with conventional processes because of metallurgical issues or environmental considerations.
At present, DST most advanced proprietary processes are associated to the extraction of precious metals using a chlorination process which provides a cyanide-free alternative for the exploitation of gold deposits. The primary benefits of the innovative technology are shorter processing times, a closed-loop operation eliminating the need for costly tailings pond, and a reduced environmental footprint related to the inert and stable characteristics of the cyanide free tailings.
The chlorination process developed by DST is a recognized “green technology” for which it was awarded a $5.7 million grant for the construction and operation of a demonstration plant. The plant will serve as a demonstration platform for the chlorination process on an industrial scale and under continuous operating conditions.
In addition to this chlorination process, DST completed the construction of a pilot plant designed to demonstrate its arsenic stabilization process which is designed for the sequestration of arsenic in a stable glass form. This process is becoming an attractive technique to segregate the arsenic and is therefore opening opportunities for materials considered to contain too much of this toxic material to be exploited or stabilized using conventional approaches.

About Dundee Sustainable Technologies, a company controlled by Dundee Corporation
DST is engaged in the development of technologies for the treatment of complex material from the mining industry. DST proprietary processes are applied for the extraction of precious and base metals and for the stabilization of contaminants, such as arsenic, from ores, concentrates and tailings, which cannot be extracted or stabilized with conventional processes because of metallurgical issues or environmental considerations.
At present, DST utmost technological advances are associated to the extraction of precious metals using chlorination. This process provides a cyanide-free alternative for the exploitation of gold deposits. The primary benefits of the innovative technology are shorter processing times, a closed-loop operation eliminating the need for costly tailings pond, reduced environmental footprint related to inert and stable characteristics of the tailings.
The chlorination process developed by DST is a recognized “green technology” for which it was awarded a $5.7 million grant for the construction and operation of a $25 million demonstration plant. The commissioning of the demonstration plant, with a capacity of 15 tonnes per day of concentrate is expected to be completed by the end of October 2015 and will serve as a platform for the chlorination extraction technology on an industrial scale.
In addition, DST is currently constructing a pilot plant for its arsenic stabilization process which calls for the sequestration of the contaminants in a stable glass form. This process is becoming an attractive technique to segregate the toxic material and is therefore opening opportunities for materials considered to contain too much arsenic to be exploited or stabilized using conventional approaches.
DST has filed, published and granted patents for these processes in several countries.

Dundee Sustainable Technologies Enters Into an Agreement with ENAMI
MONTREAL, QUEBEC–(Marketwired – Sept. 23, 2015) – Dundee Sustainable Technologies Inc. (“DST“) (CSE:DST) is pleased to announce that it has entered into an agreement with Empresa Nacional de Minería, Chile (“ENAMI”) for the processing of gold concentrates (the “Concentrate”) produced by ENAMI’s operations, using DST’s proprietary Technology (the “Agreement”).
DST purchased from ENAMI 2 Tonnes of Concentrate to be used for a piloting campaign (“Piloting”), according to given metallurgical discounts and treatment charges and will retain all of the metal value extracted during the Piloting. The concentrate was received by DST in its Thetford Mines facility on September 15th.
This Agreement is part of a phased approach established between DST and ENAMI with the objective of implementing a processing facility, utilizing DST’s patented technology, in Chile.
The Piloting will further support the applicability of the DST process. Following the Piloting, DST and ENAMI will advance towards developing the technical and economic feasibility criterias for the implementation on a commercial scale of the DST process in Chile.
About ENAMI, a Chilean state-owned company
ENAMI’s mission is to promote the small and medium size private mining sector in Chile, by supplying technical, financial, metallurgical, production and trading services to small and medium size miners. ENAMI’s assets include one smelter, five processing plants and a network of technical support and facilities. ENAMI purchases ore and concentrate from producers in various purchasing agencies located throughout Chile.
About Dundee Sustainable Technologies, a company controlled by Dundee Corporation
DST is engaged in the development of technologies for the treatment of refractory ores containing sulfides and arsenic. DST has developed proprietary hydrometallurgical processes, and owns the related patents, for the extraction of precious and base metals from ores, concentrates and tailings, which cannot be extracted with conventional processes because of metallurgical issues or environmental considerations.
DST’s patented approach provides a cyanide-free process to allow the exploitation of gold and other deposits that would otherwise face metallurgical issues with conventional methods. The primary benefits of the innovative technology are shorter processing times, a closed-loop operation eliminating the need for costly tailings pond, reduced environmental footprint related to inert and stable characteristics of the tailings, and lesser emissions due to lower energy consumption.
The process developed by DST is a recognized “green technology” for which it was awarded a $5.7 million grant towards the construction and operation of a $25 million demonstration plant. With a capacity of 15 tonnes per day of concentrate, the demonstration plant will serve as a proof of concept for the chlorination extraction technology on an industrial scale and under continuous operating conditions.
DST has tested several different gold deposits, both oxide and sulfide ores at the lab level and at its pilot plant. These tests have, consistently achieved gold recoveries in excess of 90{92d3d6fd85a76c012ea375328005e518e768e12ace6b1722b71965c2a02ea7ce}, using chlorination instead of cyanide.
