Abstract: Electrolytic apparatus is described for purifying an aqueous solution of an alkali metal hydroxide containing an impurity of a soluble heavy metal complex comprised of a heavy metal cation and a plurality of anions.For example, an aqueous solution of sodium hydroxide containing a soluble heavy metal complex, such as mercuric polysulfide, [HgS].sup.+ S.sup.-, is charged to the electrolytic chamber of an electrolytic cell. An electric current is employed to reduce heavy metal cations to a separate phase in elemental form, and simultaneously to oxidize anions to a separate phase in elemental form, and to form a slurry of the separate phases in elemental forms in the aqueous solution.The slurry is removed from the electrolytic chamber and the phases of elemental forms are separated from the purified aqueous solution. The purified alkali metal hydroxide solution is sold commercially or otherwise utilized.
Abstract: Disclosed is a process for separating precious metals such as gold or platinum from acidic solutions having a pH below about 3, which comprises the steps of:(a) adding a sufficient amount of a heavy metal chelate (e.g., zinc or iron) of 2-mercaptopyridine-N-oxide to the acidic solution to cause at least a portion of the precious metals in the solution to transchelate with the heavy metal chelate of 2-mercaptopyridine-N-oxide and then to form precipitates in the solution; and(b) separating the precipitated precious metal chelates of 2-mercaptopyridine from the acidic solution.

Abstract: Described is a mixing apparatus and its use in the hydration of liquid polymers. The apparatus includes two packed mixing columns, each having two reducing couplings attached thereto to form an inlet and an outlet to each column. The outlet of the first mixing column is connected to the inlet of the second mixing column via means of a reducing passageway. The apparatus also has sources of supply for liquid polymer and water connected to the inlet of the first mixing column through metering means and injection check means. The apparatus provides controlled mixing velocity during the hydration with non-shearing agitation and without a chemical buildup.
Abstract: A non-adherent glove-like diaphragm structure for use in an electrolysis cell. The diaphragm structure has a finger means with an open upper end, and closed lower end, and a middle section connecting the upper and lower end. The lower end is perforated so as to receive an anode riser therethrough. The diaphragm structure also includes a border for attaching the finger to the upper edge of the cathode so as to separate the cathode from the anode and the anolyte of the electrolytic cell.
