Quartz is one of the most mined mineral in America. To mine them you pull them out of a big hole. Sometimes you need dynamite in this equation. Quartz is surface mining. That means you mine at the surface or very close to it. You can say in one way that it is valuable because it has many uses, but there is so much of them so they are not rare. You use them for; radios, jewelery, sandpaper, glass, soap, and many, many more. They can be transparent or opaque. You cannot say America only depends on quartz because there are many others that we need but they do play a big role in our life. For all almost all minerals you you export them to get others. I think you should not export quartz the most but you should because quartz is very abundant.
