DEFINITION

Classification: 209/179

(under subclass 175) Processes involving electrical treatment limited to amalgamation or which are promotive of amalgamation and have no other utility. Such process does not ordinarily include cases involving the use of mercury charged

with a reagent for decomposing salts or compounds of the metal sought, with incidental amalgamation.

(1) Note. This subclass includes such processes as are not classifiable in the subclasses indented hereunder, generally processes in which both the material being separated and the mercury or its equivalent are affected by the electrical treatment or in which the effect is not definitely assignable to either.

(2) Note. This subclass and subclass 181 do not include processes in which the material being treated or a portion thereof is electrolytically decomposed to facilitate a separation not limited to amalgamation, for which see Class 204, Chemistry: Electrical and Wave Energy.

SEE OR SEARCH THIS CLASS, SUBCLASS:

180, and 181, for other processes involving electrical treatment in connection with the amalgamating (see (2) Note).

SEE OR SEARCH CLASS 204, Chemistry: Electrical and Wave Energy,

194+, for electrolytic apparatus.

205, Electrolysis: Processes, Compositions Used Therein, and Methods of Preparing the Compositions,

558+, for electrolytic processes of producing mercury alloys (see (2) Note.).
