<p>described as "the single most important operation used for the recovery and upgrading of <a href="page.php?w=Sulfide_mineral">sulfide ores</a>". The development of <a href="page.php?w=froth">froth</a> flotation has improved the recovery of valuable <a href="page.php?w=minerals">minerals</a>, such as <a href="page.php?w=List_of_copper_ores">copper</a>- and <a href="page.php?w=Lead">lead</a>-bearing minerals.
