Abstract
A laminated trough for a spiraled mineral concentrator; the trough composed of two or more laminates, chemically bonded, and the process for constructing the same. The trough includes a top laminate of highly abrasion-resistant soft elastomer, the elastomer applied as a liquid directly to a release treated mold; and a bottom laminate composed of a rigid material which is applied to the soft elastomer before final curing of the latter, the bottom laminate providing structural support for the soft elastomer. An intercoat, chemically bonded to both top and bottom laminates, may also be provided.
