sizings (P80 = 12 micron), while the remainder require ultra-fine grind sizings (P80 = 7.5 micron) for liberation. This range of textural associations allows the use of a flowsheet using staged grinding and staged flotation to remove liberated valuable minerals with a coarse grind, while composite particles are reground for further liberation .
Even though the vast majority of copper EDM electrodes for injection mold making are machined by CNC machines, knowing how to grind copper is a valuable skill in the surface grinding process.There is always the odd job, or rework that requires manual grinding of copper.
