The ore consolidation process is a thermal process and it happens at the temperatures of the ore melting beginning, allowing the ore grains, additives and fluxes to be connected into a solid piece of sinter. The amount of carbon in the sinter mixture and the FeO content of the produced sinter affect the mechanical resistance of the sinter. Indicato...

This paper presents an experimental study to evaluate the possibility of CEM IV 42,5N producing by increasing the specific cement surface from 3180 to 3850 cm2 /g. In this paper, fly ash is used as a cement admixture because fly ash possesses both hydraulic and pozzolanic properties. If one part of the clinker, as a major cement admixture, is repla...

The process of the pulp washing is very important both economically and environmentally, since the quality of cellulose washing is directly related to the efficiency of chemical regeneration and the quality of the wastewater generated. The purpose of the cellulose fiber washing process is to economically remove the maximum of soluble organic and so...
