EDMONTON, ALBERTA--(Marketwired - Jan 31, 2017) - Iberian Minerals Ltd. (the "Company" or "Iberian") (TSX VENTURE:IML)(SLDRF) is pleased to announce that an independent White Paper highlighting a 13 month study of the EnviroLeach Process has just been published. The White Paper, named; A Technical Overview of the EnviroLeach® Gold Recovery Process, was written by Ish Grewal, M.A.Sc. P.Eng. and Alex Lum, P.Eng. of Met-Solve Laboratories Inc., located in Langley, B.C., Canada.
The results of the detailed testing and analysis by Met-Solve Labs included the preparation and leaching of a number of ores, concentrates and tailings from a number of mines from across North America. Each material was subjected to a number of tests in a variety of conditions in an effort to determine the optimal leach kinetics of each. The White Paper concludes that the EnviroLeach process, outperformed cyanide on both leach kinetics and total amount of precious metals recovered into solution on most materials tested. The study also concluded that optimal leach kinetics were achieved at a near neutral pH and under ambient temperature.
Lab scale (150lb) pilot plant tests have been completed by EnviroLeach staff and indicate positive scalability. Air quality emission tests by ALS Environmental also indicates that the process does not produce any hazardous off-gassing. Continued tests will include further chemical optimization, reusability, economic studies, and the completion of larger scale pilot plant testing on a number of ores and concentrates.
Duane Nelson, CEO and President of EnviroLeach, states: "I am very pleased with the results of this study. The independent White Paper on the EnviroLeach process clearly confirms that the patent-pending EnviroLeach process has potential to become a safe and effective alternative to cyanide for the mining sector. Improved leach kinetics, shorter processing times, variability of operating parameters and the increasingly stringent environmental policies worldwide will be the main drivers for this new technology."
The EnviroLeach process is similar to a cyanide circuit but much safer and simpler. It involves the dissolution of the precious metals into the aqueous solution followed by extraction using conventional methods such as electrowinning, carbon absorption or precipitation.
Some of the benefits of the EnviroLeach process to operators include: reduced environmental impact, broad applicability spectrum, accelerated permitting process, access to cyanide prohibited mining jurisdictions, reduced operational costs, improved occupational safety and reduced tailings emissions.
