The Floatation Product

[nozzpack]

Trying to understand exactly what is planned here in terms of output and addressable market, neither of which are provided by management.

So, in the Biox process of converting sulphide ore to oxide ore for final processing, first you crush and grind the sulphide ore into very fine particles.

Then, this fine ore is passed through a floatation tank in which a dissolution process separates the sulphide gold from the ore which floats to the surface in bubbles.

This floatation of sulphide gold is then skimmed off the surface ( Stage 1 ) and sent to the Biox plant where it is converted to oxide gold ( Stage 2 ) which is then recovered by the normal CIL ( Stage 3).

So what they are proposing here is to separate the sulphide gold from the ore by floatation which is the stage 1 process.

The product will then be sulphide gold fines which will be sold to customers in the paydirt market.

At least that is my understanding ..

What will be the feedstock ? Ordinary granite ? Mengapher magnetite ? If its the paydirt market, $60 US per gram and higher, so cheap feedstock can be quite profitable. Anyone know more ?

As far as I can now determine is that a concentrate of sulphide gold will be produced by the floatation plant for sale to buyers who can complete the oxidation process. Approximate purity will be about 90% gold. Presumably, the feedstock will be fresh rock from Selinsing..

DITO, the idea is great Step 1 proposes the construction of a flotation plant producing gold concentrates for sale to a third party, with cash generated from these sales to be used as construction funding for the planned stage 2 BIOX plant.

Based on the 2019 feasability study, The design capacity of the floatation plant is 950,000 t/a with a weighted average head grade of 1.92 g/t gold and 0.64% sulphur. Recovery would be in excess of 90%. Based on these parameters, the floatation plant would produce about 55,000 ounces of sulphide gold concentrate per year . The buyer would need to oxidize the concentrate and then recover

I can confirm that it is the stage 1 sulphide gold concentrate ..the product of grinding into fines and then concentrated by floatation ...that will be produced. I noticed that such exports by Barrick , Lundin and others are quite common..
