Abstract

A compressing element, devices for using such a compressing element and methods of use are provided, in which the compressing element has: a upper surface provided with an inlet and an outlet; a lower surface; an at least partially hollow interior provided between the upper surface and the lower surface, the hollow interior being connected to the inlet and the outlet; the hollow interior being provided with: one or more fluid flow constraining surfaces provided by one or more walls of the follow interior; and one or more fluid flow control elements provided in the hollow interior, the one or more fluid flow control elements being additional to the one or more fluid flow constraining surfaces provided by the one or more walls of the hollow interior. The arrangement of inlet, outlet, fluid flow constraining surfaces and fluid control elements provides for improved cooling of the compressing element, for instance when used to press molten metal processing by-products to extract molten metal.
