What does a Precipitator I do?
Tends equipment that precipitates gold or silver from cyanide solution: Packs zinc shavings into compartments of zinc boxes. Regulates flow of solution through boxes where gold or silver precipitates on zinc. Shuts off flow of solution and turns on water. Agitates shavings to remove precipitate. Pulls plugs and draws off slime from boxes. Treats slime with sulfuric acid. Turns slime solution into filter press that filters solution and removes precipitate residue. Washes precipitate with water under pressure, and dries it with compressed air.
