RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:CYANIDE now banned in Costa Rica, is Newlox next?Nice try at defecting the questions posed, but your rambling lecture on cyanide, whether it is sodium or potassium-based, is used in gold mining and both are toxic. A safe or eco-friendly version of cyanide which is effective at dissolving gold into solution does not exist.
Your tedious discourse does not resolve the issue of a company claiming it is using eco-friendly processes when in fact is using toxic cyanide. I have not found one corporate press release, shareholder update, tweet, post or web page divulging the use of cyanide by the company at its pilot plant.
The reprocessing of old tailings to extract gold and a remove small amount of mercury may be admirable but this minor benefit is dwarfed by the impending danger of using toxic cyanide as a part of the process. This is similar to using a wrecking ball to fix a paint blemish on a building.
Your reference to their research on alternatives such as Organic Aqua Regia is irrelevent as it is only in the lab-scale testing phase and far from a reality. In most research papers, OAR chemistry ultimately achieved only indiscriminate preliminary positive results in strictly controlled laboratory conditions on non-mineralized gold samples. No research has ever evolved beyond these strictly controlled lab-scale tests. There have been no pilot-scale tests, in-field tests, or bulk-scale tests reported to date. Due to several factors, it is not believed to be scalable to any commercial mineral-based applications. Its mention has also been removed from the company website and literature.
The most important issue here is that this company has been irresponsibly representing itself as an eco-friendly mining company using safe alternatives to cyanide when the truth is, they are not.
