of nuclear power plants are all contained in the Energy policy of the Slovak Republic. Its aim …

The bentonite from deposit Stará Kremnička and quartz sand from deposit Šaštín both from
Slovakia were modified by manganese oxides in order to increase their sorption properties …

This work refers to a process of purification of silica sand and, more particularly, to a process
of iron and aluminium removal from the Algerian silica sand particles. Iron compounds are …

Silica sands of low quality contain free iron oxides, clay and silt. These impurities may be
removed by biological leaching as well as by industrial washing. The fine fractions obtained …

Feed fractionation of a silica sand sample to a rare earth roll separator (RER) magnetic
separator was found to be much more favorable for separation than the whole batch. The …

Quartz sand occurs in varying degrees of purity in dependence on the iron mineral
composition, but only a small percentage is suitable for the glass industry after washing and …

The bioleaching processfor silicate industrial minerals using heterotrophic bacteria is a
technology that has not beenapplied onindustrial scaleyet. The laboratory experimentsofiron …

Kaolin, silica sand and high grade carbonates are industrial minerals widely and extensively
used as fillers and coating agents in the manufacture of paper, ceramics, glass, paint and …

Kaolin is a naturally occurring raw material for several industrial applications. Moreover, the
