With limited competition and few high-grade resources worldwide, the market for high-purity quartz should be a tough nut to crack. Yet with leading producers working side-by-side and others focusing on targeted end-market specifications, progress has been steady even throughout the challenging financial period of late. Emma Hughes, Deputy Editor, takes a closer look at these projects.
Quartz is one of Earth’s most abundant minerals and
occurs in many different geological settings. It is best known
for its use in glass manufacturing, yet different types of
end-markets require differing levels of silicon dioxide (SiO2)
content. Very few deposits can be classified as high-purity
quartz (HPQ), which can...
