Santacruz Silver Mining reports fatality at Tres Amigos mine in Bolivia
Tres Amigos mine, a part of the Caballo Blanco Group of mines, has resumed operations after it was shut down following the incident.
Researchers have discovered a new way to separate gold, silver, copper and other valuable metals from ore using the flotation processing method, reports MEI Online.
In flotation, the minerals are crushed into small particles then floated to separate the metals from the waste rock, using a “collector” that attaches to the particles allowing them to be skimmed off.
The new process, described in the ACS journal Langmuir, uses water-repelling nanoparticles. MEI says in experiments using glass beads to simulate the minerals, recovery rates were near 100%.

Is this can save processing cost?
