I have quite a bit of course sand which I will be putting over the garden, I know that you can buy "rock dust" for adding more minerals to your soil, but can anyone tell me if course sand adds mineral content as well

I believe coarse sand is composed mostly of silica, which is very hard and is not particularly soluble in water (otherwise we wouldn't have beaches ). Rock dust or ground basalt contains a mix—phosphorus, potassium, calcium, magnesium, iron, all of which dissolve in water, allowing the plants to absorb them.Location - Leicestershire - Chisit-land
Endless wonder.

The 'washed' description denotes that any organic or fine mineral particals are removed. If you have heavy soil then some sand will aid it in not sticking together so badly, but time and lots (and lots) of organic material is a better and more effective solution to that problem and many others.
In the past i have tried adding sand to heavy soil, it does no harm in the quantities I had but I've definitely had much better results digging in or shovelling on organic stuff. I've now got soil in my front garden that most people would call nice compost (after years of repeated applications), the sand early on does no harm and probably gives the worms something to aid thier digestion.
