Mar 27, 2020· An Integrated Supply Chain from mining to international logistics and sales. Situated about 220 kilometers north of Cairns, Cape Flattery is home to one of the world's largest silica mines. MC have started importing silica sand from the mine to Japan in 1968, purchased CFSM in 1977 and built a wharf and shipping facilities in the late 1980s.
Silica sand (also commonly referred to as frac sand) is a crucial ingredient in the oil and natural gas extraction process known as fracking. The hydraulic fracturing ("fracking") process for oil and gas takes a mixture of proppant (usually frac sand), water, and chemicals and injects this mixture into a well under very high pressure.
Silica. Also called silica sand or quartz sand, silica is silicon dioxide (SiO 2). Silicon compounds are the most significant component of the Earth's crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source.
Steps of a typical frac sand mining operation. This aerial photograph is numbered in the order steps occur, from start to finish. Each step is described below. While individual mine operations may handle various steps slightly differently, the basic order remains the same.

Sand mining is the extraction of sand, mainly through an open pit (or sand pit) but sometimes mined from beaches and inland dunes or dredged from ocean and river beds. Sand is often used in manufacturing, for example as an abrasive or in concrete.It is also used on icy and snowy roads usually mixed with salt, to lower the melting point temperature, on the road surface.
