It is unprocessed in the sense of the poster I was replying to, meaning it is not composed of man made chemicals. It's just rock. Sorry to have been careless - but hell, you really didn't know what I was talking about? No, it's not. It's one step - one very, very, well paid and profitable step - from that. Inches, not miles, would be the metaphorical unit; single digits the metaphorical number. "Obviously" ? Beg to differ. Living and learning about hard rock mining corporations (and related industry). Minus your exaggerated cartoon of unconcealed mine spoil, crediting the bad guys with some minimum of brains here, that is exactly what will happen in the absence of the regulatory oversight I partly detailed above. The expense and the scale of the efforts necessary to impose regulatory oversight on a hard rock mining company is a factor in this proposal, is all. It's part of the calculation.
