RE:RE:RE:RE:CYANIDE now banned in Costa Rica, is Newlox next?Unbelievable... All of the cyanide (CN) compounds and you refer to are highly toxic to the environment and none of them are “natural organic safe versions of cyanide”. Any of the (CN) compounds that can dissolve gold into solution are extremely hazardous and are prohibited in most countries.
You also state that Newlox is researching various alternatives to cyanide. The whole world is. The lab-scale research you refer to is just that, early-stage research which, even if successful, will be subject to the same permitting and prohibitions as conventional cyanide.
