Among specific topics are recovering valuable metals from copper slag by hydrometallurgy, fluid flow in a large round bloom continuous casting mold, the kinetics of pressure acid leaching of zinc from zinc silicate ore, cost optimization of pig iron, a large-scale rotary steam tube drying system and equipment for copper powder, permeability characteristics of soft coal
under higher confining pressure, virtual simulation of the ground scene of the mining area, and a technique to measure a metal tank's oil temperature and level.
But I have this little niggling thought - could this major change in our weather patterns be linked in any way to our ceasing to burn soft coal
in our houses and factories at about the same time?
