Nepheline syenite ore is an essential constituent in ceramics and glass raw material meals, as a flux and as a source of alumina. The natural nepheline syenite rocks contain some undesired minerals, which are usually eliminated or reduced to the allowable limits by beneficiation. The present paper is concerned with characterization and beneficiation of an Egyptian nepheline syenite rock, …

Milling machines, also called pave-ment profilers, were first available in the mid-1970's. Fig. 13 shows a typical half-lane, rear-load milling machine of the 1970's. Today's milling machines like the front-load model shown in Fig. 14 are more productive and versatile than the early machines, and as a result, the cost of milling has been

The use of solid wastes rich in Ca 2+, Mg 2+ and Fe 2+ for the ex situ sequestration of CO 2 could provide an economically and technologically viable option for the reduction of anthropogenic CO 2 emissions. Here, we investigate for the first time the potential use of waste materials from mafic rock quarries as a feedstock for the sequestration of CO 2 by ex situ mineral carbonation.
