Water carry over recovery (3 replies and 2 comments)

Good day guys, I am interning at a Gold mine here in Namibia where we seem to be having way to much water being carried over onto our conveyor belts and later on into our concentrate/tailings bins. This water can be seen as a loss of water from the circuit as is it hardly recovered. Is there any way of recovering water from these bins back into the process before we consider altering our washing and dewatering screens?

While there are some methods, such as floor drains and trenches to collect water and pump to thickeners, they are all masking the symptoms.  If you have significant water carry over you have other more serious problems.  Why is this happening!  Are the screens undersized?  Are the screen decks plugged?  Are screens even the right equipment?

I think the screens are undersize. I do not want to temper with the feed rate as this might decrease overall throughput. Will suggest that in my presentation but oh well,
I am just an intern.

Hi Fuloshixwa,

I also worked in Namibia - at Oranjemund. Great place to be!!

Smart dog is right, best to cure the issue as early in the process as possible.

You could install drain panels into your bins but it is a tricky modification.

I have seen this problem many times before and there are many ways to fix it without installing new equipment.

If you send your flowsheet to me, I can advise.

Cheers

I could send you a flow sheet but I am afraid that could be against company policy.
