· Traditionally, gold mining has depended on harsh chemicals such as cyanide and mercury to extract gold from ore. This has left our planet with a legacy of toxic waste which is harmful to health and the environment. For over 50 years, the industry and leading research institutions have been trying to find such an alternative without much success.
Cleaning gold without acid?
Plop in your gold nuggets and put the bottle on the shelf. Everytime you walk by, give the bottle a good shaking. The vinegar is a weak acid and the salt acts as a mild abrasive. Doing this process for about a week o rless in some cases will remove the majority of those oxides and leave the gold bright and shiny without nasty chemicals. Michael.
