#Dundee Sustainable Technologies innovates in nickel extraction Dundee Sustainable Technologies the developer and owner of proprietary technologies to serve the natural resource sector with environmentally friendly procedures has announced an innovation in the nickel extraction. The company has reported 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. This approach has simplified greatly the collection of nickel from laterites as per the following table: The cyanide and mercury free gold extraction process developed by DSTI has been recognised as a green technology for which DSTI has been awarded $5700000 in grants to date for a demonstration plant presently under construction in Thetford Mines Quebec c
