Weigh the silver and put it in one or more 5 gallon buckets. Add 150 ml nitric acid for every ounce of metal in the bucket (s). The acid will tend to react violently to the metal, bubbling and fuming. Make sure there is enough extra room in the bucket to accommodate the ing (2-3 times, or more, the volume taken up by the silver).
thorium processing, preparation of the ore for use in various products. Thorium (Th) is a dense (11.7 grams per cubic centimetre) silvery metal that is softer than steel. It has a high melting temperature of approximately 1,750 °C (3,180 °F). Below about 1,360 °C (2,480 °F), the metal exists in the
