gravity concentration of g from cyclonewhere there is gravity recoverable g, it is important that it be maximized, as the unit operating cost for a gravity circuit is much lower than that for any other process. minimizing the size of the gravity concentration circuit many process engineers view gravity concentration in g grinding circuits as a nuisance and a security risk.multi gravity separator gravity miningrecovery of fine free g is an underdeveloped opportunity for the mgs and is a focused area of growth for us. the mgs or enhanced gravity separator is our core product and is available as a production mgs machine, a pilot plant mgs or laboratory mgs. we also carry a full range of spares for the c900, c902, scmg1, scmg2 and c800 machines.gravity concentration an overview
