The silver rich froth is skimmed from the bath and smelted so that it can be separated from other metals. Silver derived from copper and its derivatives including copper sulfide requires different handling and refining techniques than silver minerals taken from zinc deposits and lead sources.

Refining Of Gold And Silver Bearing Dore Sciencedirect

It is basically the same procedures with the nitric acid but this way may be easier to not lose any silver particles.

Process of refining silver. During my study of the refining process i ran into a verse in jeremiah 6. While reading this verse i realized that not all silver will be refined. The resulting cathodes are 99 9 pure silver.

The resulting cathodes are 99 9 pure silver. The electrolytic silver refining process is similar to gold except that the silver anodes are dissolved in a bath of nitric acid. Use baking soda along with karo pancake syrup salt water and red devil drain cleaner in order to use a different process of refining silver.

From zinc concentrates zinc concentrates are roasted and then leached with sulfuric acid to dissolve their zinc content leaving a residue that contains lead silver and gold along with 5 to 10 percent of the zinc content of the concentrates. As with small gold bar production these cathodes are melted granulated and cast into retail sized bars most common being 100oz or kilo. The silver will refuse to let go of impurity.

The electrolytic silver refining process is similar to gold except that the silver anodes are dissolved in a bath of nitric acid. You will begin by dissolving the silver with acid in the plastic bucket. The residue from silver refining is treated by affination or parting to concentrate the gold content which is refined by the wohlwill process.

As with small gold bar production these cathodes are melted granulated and cast into retail sized bars most common being 100oz or kilo. Some silver contains metals that cannot be removed with fire. Air bubbles are blown through the mixture to carry the silver to the top of the bath where it forms froth.

A diagram illustrating the froth flotation process. When that happens the silver is rejected by the refiner unable to be purified. Silver is found embedded in several different minerals namely copper zinc and lead and the refining process varies depending on the source.

In this process crushed ore is placed in a bath.
