Abstract: Method and apparatus (10) includes the use of multiple containers (B-1-B-3) containing a weak base ion resin (R) through which plating rinse water (W) is pumped with precious metal such as potassium gold cyanide adsorbed by said resin and then with the cyanide sequentially eluted by potassium hydroxide, water, potassium thiocyanate, water, and the resulting effluent evaporated (at 40) and then chilled (at 44) to remove for reuse the gold and inorganic salt and base.

Abstract: This invention includes a method featuring steps having a transport (64, 68) to carry metal articles (10, 14) through a vacuum chamber (62, 66, 90) containing a plasma cleaning station (32) followed by exposure to an evaporant of metal (42) generated by an E-Beam (50) caused to condense on the articles in high vacuum. A channel structure (51) is provided to cause selective condensation upon the surface of said articles. The apparatus includes several stations (101, 102, 103) to provide multiple coatings on one or both sides of an article to be coated.

Abstract: This invention relates primarily to a waste water treatment and recycling system for an electroplating line. Electroplating lines typically produce waste products which may be defined as environmentally hazardous. The present invention provides for a system of complete recycling of such wastes from an electroplating line which includes (I) a plurality of treatment stations, where each station consists of a treatment tank and a rinse tank, and (II) means for sequentially moving metallic parts for treatment therein from a treatment tank and a rinse tank of a first treatment station, to a treatment tank and rinse tank of a second treatment station.
