How effective is gravity separation on upgrading copper ore? (4 replies and 5 comments)

I ran 6.11% copper oxide on a shaking table optimised to process chromite ore, and got 10.60% in heading, and 4.28 in middling. Copper was milled at 100 plus mesh. There was no control and hence no optimisation.

How much say 1% copper ore can be upgraded to?

If you post me a small 50g sample i will pass it over a mozley lab separator ans post the concentrate back to you. Pm me for my address. T

50 grams. Will that be enough? I can send upto 5 kg.

Yes 50g is sufficient but send a little more (100g) in case I need to retest.

Tariq, do you have the weights of those streams?

Tariq

No, unfortunately not. But I plan to run the tests and plant to take weight into account.

You need the weights. Otherwise, you are wasting your sample. Is this a research program or what?

It will never give you great recovery, you can be sure. At 6% Cu, you should test flotation. The only time a saw copper concentrate on a table was with native copper or electronic scrap.

Will take weights into account on the next run.
We are checking for the possibilities of processing copper ore like chromite ore.
And would like to know of what other gravitational separation machines can be used to get good results.

Thanks, I would really appreciate this sort of work done on copper, if any.
