recovery of copper from oxide copper ore by flotation and leaching a thesis submitted to the graduate school of natural and applied sciences
When rich enough, native copper ore bodies may be treated to recover the contained copper via a gravity separation circuit where the density of the metal is used to liberate it from the lighter silicate minerals. Often, the nature of the gangue is important, as clay-rich native copper ores prove difficult to liberate.
