Quartz The mineral Quartz information and pictures

Quartz is an important mineral with numerous uses. Sand, which is composed of tiny Quartz pebbles, is the primary ingredient for the manufacture of glass. Transparent Rock Crystal has many electronic uses it is used as oscillators in radios, watches, and pressure gauges, and in the study of optics.

The coastal heavy mineral sand deposits of Africa South

The coastal heavy mineral sand deposits of Africa South

The formation of an economically viable deposit requires the juxtaposition of most, if not all of these conditions to favour heavy mineral concentration with a high VHM content. Mining is by open cast using either dry mechanized, hydraulic monitoring, or floating dredge and wet concentrator methodologies.

On the Mechanism of the Dissolution of Quartz and Silica

On the Mechanism of the Dissolution of Quartz and Silica

However, quartz and other silicate minerals can be a source of dissolved and colloidal silica, which result in poor filtration and settling properties in industrial applications. Hence, the topic of the dissolution of quartz is of interest to material scientists, chemical engineers, biologists, environmental scientists, and geochemists, and ...
