(\u201cDSTI\u201d or the \u201cCorporation\u201d) (CSE: DST), the developer and owner of proprietary technologies to serve the natural resource sector with environmentally friendly procedures, is pleased to announce an innovation in the nickel extraction.<\/p>\n<p style=\"text-align: justify;\">The Corporation is pleased to report the successful application of its patented proprietary process for nickel extraction from laterites for the production of nickel sulfate. This new concept was applied on laterites from Guatemala, Cuba and the United States, and achieved a nickel extraction ranging from 95% to 97%, at ambient pressure and moderate temperature, over a short period of time.<\/p>\n<p style=\"text-align: justify;\">This approach has greatly simplified the collection of nickel from laterites as per the following table:<\/p>\n<table class=\"table\">\n<tbody>\n<tr>\n<td>&nbsp;<\/td>\n<td><strong>DSTI<\/strong><\/td>\n<td><strong>Pressure leaching<\/strong><\/td>\n<td><strong>Ferro-nickel<\/strong><\/td>\n<\/tr>\n<tr>\n<td>Extraction yield<\/td>\n<td>Typically 95%<\/td>\n<td>Typically 95%<\/td>\n<td>Typically 80%<\/td>\n<\/tr>\n<tr>\n<td>Processing time<\/td>\n<td>15 minutes<\/td>\n<td>Several hours<\/td>\n<td>Continuous<\/td>\n<\/tr>\n<tr>\n<td>Pressure<\/td>\n<td>Atmospheric<\/td>\n<td>Pressurized<\/td>\n<td>Atmospheric<\/td>\n<\/tr>\n<tr>\n<td>Temperature<\/td>\n<td>Ambiant<\/td>\n<td>Above 150 oC<\/td>\n<td>Above 1 000 oC<\/td>\n<\/tr>\n<tr>\n<td>Limitations<\/td>\n<td>No limit for MgO and SiO2<\/td>\n<td>Low MgO content<\/td>\n<td>Limitation on MgO, SiO2 and Al2O3<\/td>\n<\/tr>\n<tr>\n<td>Environment<\/td>\n<td>Low impact<\/td>\n<td>Low impact<\/td>\n<td>Significant impact high carbon oxides emission<\/td>\n<\/tr>\n<tr>\n<td>Capital costs<\/td>\n<td>Low<\/td>\n<td>Expensive autoclaves pressurized equipment<\/td>\n<td>Expensive arc furnace and pelletizing equipment<\/td>\n<\/tr>\n<tr>\n<td>Operation costs<\/td>\n<td>Low energy dilute sulfuric acid<\/td>\n<td>Autoclave maintenance, high pressure oxygen, concentrated sulfuric acid<\/td>\n<td>Most costly nickel (high energy consumption)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":0,"menu_order":654200,"template":"","class_list":["post-39504","news","type-news","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/dundeetechnologies.com\/fr\/wp-json\/wp\/v2\/news\/39504","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=39504"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
