The Quantitve Measurement of Amalgamation

Mercury has been known since ancient times. In fact, one mine, the "Almaden" in Spain, has been worked continuously since Roman times. It has been used during all this time for the recovery of free gold from gold concentrates, and from black sand and galena in concentrates from placer work.

The Determination of Aluminum in the Presence of Manganese and Iron by the Use of a Mercury Cathode

Since 1880, when Wolcott Gibbs made the suggestion that mercury could be used as a cathode in gravimetric electroanalysis, many articles have appeared in literature either criticizing the method or citing successful results which have been obtained by it.

Apparatus and Method for Removing Mercury Vapor from a Gas Stream

A metallic filter effectively removes vapor from gas streams. The filter captures the mercury which then can be released and collected as a product. The metallic filter is a copper mesh sponge plated with a six micrometer thickness of gold. The filter removes up to 90% of mercury vapor from a mercury contaminated gas stream.
