Shale gas sparks fracking frenzy
Published: Tuesday, 20 March 2012
The US shale gas revolution is causing a new gold rush in fracking fluid feedstock such as frac sand and ceramic proppants. But what is unconventional drilling? And can the boom be sustained for much longer?
Demand for fracturing sand and
other industrial mineral proppants is booming, and it is all

Extracting natural gas from shale formation involves
hydraulic fracturing (fracking) - a drilling technique which
requires large amounts of water and sand to be blasted down
