Recovery of Raw Materials from Ceramic Waste Materials for the Refractory Industry

NEW REFRACTORY MATERIALS FOR THE COPPER INDUSTRY

Wear of various basic refractory materials to substitute to currently used magnesia chrome bricks has been studied, measuring matte and slag penetration and dissolution, through different cup and rotary slag tests. High magnesia with and without impregnation, magnesia graphite, magnesia-alumina spinel with and without impregnation, olivine-magnesia and olivine magnesia- graphite bricks, as well...

Natural radioactivity concentration in raw materials used for manufacturing refractory products

Background: Some Particular areas contain natural radionuclide at levels much higher than those usually present in earth's crust. The radiological impact of the use of zirconium ore in zirconium industry is due to internal exposure of the lung by alpha particles and external exposure of the body by the gamma rays. The result of gamma spectrometry measurement of the concentrations of th...

TRENDS IN THE STEEL INDUSTRY AND DEVELOPMENTS OF NEW REFRACTORY MATERIALS

At first, trends in the steel industry are briefly reviewed, taking into consideration bothmanagerial and technical issues. As a consequence of this review, the importance of electricfurnace technology and of secondary metallurgy is being underlined. The same sequence iffollowed to describe the refractory industry. Specific issues concerning the latest developments oncarbon-containing castables...

Adsorbent materials from paper industry waste materials and their use in Cu(II) removal from water.

This paper deals with the removal of Cu(2+) from water using adsorbent materials prepared from paper industry waste materials (one de-inking paper sludge and other sludge from virgin pulp mill). Experimental results showed that de-inking paper sludge leads to mesoporous materials (V(mic)/V(T)=0.13 and 0.14), whereas the sludge from virgin pulp mill produces high microporous adsorbents (V(mic)/V...
