ucts as sand and gravel, diamonds, and gold; however, many other products, including, for example, most heavy minerals, require further shorebased processing. Chemical treatment, smelting, and refining of metals have heretofore taken place on shore, and, given the difficulty and expense of processing beyond the bulk concentrate stage at sea, are likely to continue to be done on land in most

Fundamentals As the name already indicates, the PU cold box process is based on the reaction of two components with polyurethane. A polyaddition of the part 1 component, the phenolformaldehyde resin, and the part 2 component, the isocyanate, is initiated through basic catalysis, usually by means of gassing with a tertiary amine.
