Is it true that Inhaled dust particles are cleared from the airways by mucociliary clearance and then coughed up or swallowed?

Yes. The EPA particle pollution page states that mucociliary clearance removes the vast majority of inhaled particles deposited in the tracheobronchial airways and that the particle-laden mucus is then swallowed or expectorated. Other sources (a cilia review and Wikipedia) similarly describe cilia transporting inhaled material toward the mouth to be swallowed or coughed up, though they cover only parts of the pathway.
