In a sense yes. The chemicals that animals sense become more diffuse or dissipate over time. While some animals such as bloodhounds are able to track a scent for several days, it is due to the heightened sensitivity of the sense.
Hearing loss will not usually affect a persons sense of smell.
Economically, it makes the most sense to extract the ore that is in the most concentrated form.

That depends what you mean with "disappear". If you burn something, it might "disappear" in a sense. But it really gets converted to something else - and the smoke etc., plus the heat energy, have exactly the same mass (measured in kilograms, or pounds) as the original substances.
