Concrete Block Molds

Concrete is the most used product on earth with a carbon foot print to match. Concrete users generally order more than is required as coming up short can be a costly mistake. When concrete arrives at the construction site the water has been added and the hydration process has begun so time is of the essence to recover any quality leftover concrete. New 3 piece light weight molds allow for the recovery of leftover mix at the construction site during equipment cleanouts. In today's Zero Waste so

Recovery of Metal Values from Smelter Slags

Background Many mine sites, especially in Canada , contain thousands of tons of waste slag. This slag has been generally considered to be worthless in terms of metal content, and also inert so that it can be used, for example, in railway beds. Recent results at the University of Toronto have shown that some slags are neither inert nor valueless, and that valuable metal content can be economically extracted through the use of new techniques. The fact that the slags are in fact not inert, as
