RE: InterestingWhy is MTO trying new unproven technology to implement a process as simple as concentration?
I note and take on board all you say, Btrevb. There are always grounds to be cautious with new technology, particularly when new chemical engineering processes may have to be developed. However, his may be a niche that Metanor ought to follow at Barry for the following reasons (ref www.nichromet.com :-
- The Nichromet process seems to have been tested for up to 7 years on the tailings of Canadian nickel mines, where metals have to be removed from oxide or sulphide ores.
- Since the process used a “closed loop” then there is no gaseous or heavy metal tailings problems, or liquid effluent. More importantly, it appears that the process does not require cyanide in the process.
- The nickel pilot plants have been able to demonstrate great improvements in the quantity of metal output (this seems to be particularly relevant to Ni mines, where magnesium is a major problem in congenital Ni extractions processes.
- If there are similar benefits in the extraction of gold, then low grade mines using the Nichomet process may increase gold output and simultaneously reduce costs (including green production costs).
At the present time, Barry may need far more than 25,000 meters of drilling before an optimum full capacity plant is located on the site. Also, time will be needed to determine whether Barry should cater for production from other companies with properties next to Metanor.
In summary, if the decision was solely one of replacing a conventional concentration system that was not broke, then I would agree that Metanor should not be pioneers. However, from my review of the video, on the top right corner of the nichomet website, there appears to be production benefits and also realizable chemical side products produced. More information is required before a judgment can be made. Could this be an occasion when Metanor go out on a limb and are rewarded?
