Recycling Process for Sinter-Active U3O8 Powders

Recycling of Waste Epoxy-Polyester Powders for Foam Production

This paper proposes a new foaming technology (solid-state foaming) to produce structural foams from waste thermosetting resins. The proposed technology is easy and does not require specific and expensive equipments. Solid tablets are produced by cold compaction of resin powder, and foam by heating in an oven. Composite foams can be produced by mixing fillers and resin powder before the cold com...

Harmful Admixtures Assessment in Sinter Mixtures Used in Iron Ore Sinter Plants in Poland

J. Korol, Central Mining Institute, Department of Material Engineering, Poland D. Burchart-Korol, A. Smoliński, Central Mining Institute, Department of Energy Saving and Air Protection, Poland In this study composition of sinter mixtures used in Polish sinter plants were established. Seven sinter mixtures composition were examined, based on iron-bearing materials, admixtures and fuels.

Continental moisture recycling as a Poisson process

On their journey over large land masses, water molecules experience a number of precipitation–evaporation cycles (recycling events). We derive analytically the frequency distributions of recycling events for the water molecules contained in a given air parcel. Given the validity of certain simplifying assumptions, the frequency distribution of recycling events is shown to develop either into a ...

Alternative Process Chemistries and Chemical Recycling

Decreasing feature size, low cost, and high yield continue to drive the silicon electronics industry. Perfect atomic surface silicon is therefore needed to manufacture high yield devices of submicron dimensions. In addition, there are rising environmental concerns, and EPA regulation is broadening its control over industrial environment. The solution to maintain traditional low cost wet cleanin...
