(\u201cDST\u201d or the \u201cCorporation\u201d) (CSE: DST) is pleased to announce that it has entered into an agreement with a Canadian gold developer (the \u201cDeveloper\u201d) to conduct arsenic vitrification test work using its GlassLock Process<sup>TM&nbsp;<\/sup><strong>(<\/strong>\u201cGlassLock\u201d or the \u201cTechnology\u201d) on legacy arsenic trioxide material from a gold project located within the Abitibi Region of Qu\u00e9bec (the \u201cProject\u201d).<\/p>\n<p style=\"text-align: justify;\">DST and the Developer discussed the technical feasibility and interest, by the Developer, to evaluate the applicability of the GlassLock Process<sup>TM<\/sup>&nbsp;on arsenic bearing roaster dusts from the Project. The Project is host to approximately 2,500 tonnes of arsenic bearing dusts. The arsenic concentration within the dusts is known to be between 40 and 60%, mostly in the form of arsenic trioxide. The arsenical dusts also contain a gold content up to 10 g\/t of gold. The gold recovery will be investigated, qualified, and quantified as a mean of offsetting the remediation costs associated with the stabilisation of the arsenic. As part of the Developer\u2019s environmental compliance plan\/policy, the arsenic bearing dusts represent an important liability and there is a requirement for them to be safely and permanently remediated.<\/p>\n<p style=\"text-align: justify;\">In December 2020, over 300 kg of the Project arsenic dusts were received at DST\u2019s technical facilities for the test work program. The goal of this testing program is to identify the set of conditions for the gold recovery and the successful stabilisation of arsenic using DST\u2019s Technology.<\/p>\n<p style=\"text-align: justify;\">The GlassLock Process<sup>TM<\/sup>, developed and patented by DST, is designed for the permanent sequestration of arsenic in a stable glass form. DST successfully demonstrated its Technology at laboratory, pilot and industrial scales.&nbsp; In these demonstrations, arsenical material was processed and generated vitrified arsenical glass, containing up to 20% arsenic while meeting the United States Environmental Protection Agency&rsquo;s (EPA) toxicity characterization leaching procedure (TCLP, Method 1311).<\/p>\n<p style=\"text-align: justify;\">The test work program has commenced in January 2021 and is expected to be completed within an 8-week period.<\/p>\n","protected":false},"featured_media":0,"menu_order":1061100,"template":"","class_list":["post-39579","news","type-news","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/dundeetechnologies.com\/fr\/wp-json\/wp\/v2\/news\/39579","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/dundeetechnologies.com\/fr\/wp-json\/wp\/v2\/news"}],"about":[{"href":"https:\/\/dundeetechnologies.com\/fr\/wp-json\/wp\/v2\/types\/news"}],"wp:attachment":[{"href":"https:\/\/dundeetechnologies.com\/fr\/wp-json\/wp\/v2\/media?parent=39579"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
