We always come across some customers who want to  concentrate the alluvial gold . And their alluvial gold is with some magnetic mineral,so some magnetic would stay with after gold centrifugal or jig separator . below is the flow offer by some suppl...

Hi there, I would suggest that you perform mineralogy studies first before you could rule-out the use of magnet separat...

We are considering acquiring an iCON-i350 Centrifugal Concentrator ( http://www.iconcentrator.com ); a Falcon SB350 equivalent. However, we got an attractive offer of two units of “Oro Low-G 16” Horizontal Centrifuge Primary Concentrators” (use...

Yes, if you have no gold finer than 200 mesh (74um) you might be OK with that low-G machine. Otherwise.... you need hig...

We run a Gekko ILR to leach gravity gold. The problem we have is to estimate the Au recovered using Solution assays & tons from volume measurements. The variation is always approx. -30%. Where are we missing?

Just wondering if there is a better way, environmentally, to reprocess mercury-rich gold tailings other than using a retort! The tailings belong to an old Whole Ore Amalgamation process at a saprolite deposit.
Last replied to by Amar
Gravity Concentrators can only recover about 60-70% of the mercury at best.
