Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a metallurgical technique for extracting gold from low-grade ore by converting the gold to a water soluble coordination complex. It is the most commonly used process for gold extraction. Production of reagents for mineral processing to recover gold, copper, zinc and silver represents approximately 13% of cyanide consumption globally, with the remaining 87% of cyanide used in other industrial processes such as plastics, adhesives, and pesticides. Due to the highly poisonous nature of cyanide, the process is controversial and its usage is banned in a number of countries and territories
good enough for me
just thought i'd ask here
SHELTER ( includes fire/heat )
TSHTF does not mean you stop living
you just change your definition of a " good life "
You must also legally deal with the hazardous waste that the process generates. That is VERY costly, even for the pro's. Please, leave this for professionals. Shade tree metallurgy can be dangerous and costly. Just my honest two cents. DYODD.
