RE: Gold Concentrate8 Jan 2021 10:52
There are two common 'gold concentrators' Centrifugal, the raw crushed bulk sample is spun and higher weight particles rise higher in the centrifuge drum. And wet shuffle table.. raw crushed bulk sample is fed at the top with water, the heavier particles are recovered in a number of buckets. Number one being the highest, larger size gold particles.
Alba do not have a centrifuge. They have only just set up a wet shuffle table.
The 'concentrate' then needs to be smelted from either type of separator/concentrator.
the figure of 20.7 g per tonne is referance to the raw crushed weight of the sample. NOT after concentration
