Good news for Thames economy

I am reminded that back in the 70s I lived in Cornwall. At the time there was a reported shortage of sand in the South-East of England, where there was a lot of building, development and road construction going on, while in Cornwall the place was littered with vast spoil heaps of the stuff (then 'white mountains', but since largely grassed over). I couldn't understand why our then nationalised railways couldn't arrange for the two problems to cancel one another out. I have since lowered my expectations.
 
There is a worldwide shortage of sand.
Worth bearing in mind that "sand" comes in many types! Mostly it's sand made of quartz grains, which might be rounded or angular - that matters, I understand, when it comes to its use in concrete. But sand is a grain size definition, not a composition. The sand in the Cornish waste tips, for example, will have a high quantity of feldspar as well as quartz, and that would render it unsuitable for building use (Feldspars break down slowly into clay minerals in the presence of water; hence the China Clay deposits in Cornwall!). And some sand is made up of other minerals - black sand results from the breakdown of some volcanic rocks; there's even radioactive sand containing thorium in some places! Many other minerals can occur in sands, but as far as I'm aware, only fairly pure quartz sand is suitable for building.

Unless you are a coral reef :)


The major supplier of sand in the UK is British Industrial Sand (unless it has enjoyed a name change). Big markets are foundry, glass and construction. BIS was part of General Refractories, taken over by Hepworth Ceramic Holdings and BIS was part of Hepworth's Minerals Division. There is no shortage of 'sand' there is a shortage of higher purity sand for ceramic fibres etc. Sand deposits can be upgraded - at a cost. BIS held leases on UK sand deposits that they did not work, reserves.

Many rare earths are sand deposits (and they are in short supply). Rutile is also mined as sand.

Allied Eneabba mined mixed sands in Australia that they sorted, Rutile, Ilmenite, Zircon, kyanite which were exported to, for example, the UK,). Now the big potential is for Rare Earths under the Iluka name.

So, some, sand is definitely in short supply for example rare earths but beaches are fairly safe.

I have been reading Maurice Griffiths and his Thames predecessors from the 1890s. They would be pleased to know that their Swins and Swatchways are safe.
