bb, the are saying:
DMS test work on the Ngoualana Prospect mineralisation returned primary concentrate grades of 6.0% Li2O at recoveries of up to 70%. That is because it has the large mineral grains.
· A master composite comprising 70% Sogola-Baoulé and 30% Ngoualana tested initially with the DMS circuit was followed by downstream flotation test work which improved overall recovery to 75%, producing a 6.0% grade Li2O concentrate.
so they are testing two option, as to up to 70%, that is because they used different cashing grades, one of them produced the 70%, not necessarily the finest one, as this will create fine dust which will need flotation.
so we have two paths start using the first option, it is cheap and produce 70% or mix the lot (30:70) and use the more sophisticated process and produce 75%.
If they adopt the first process, we will have 3 years production then we will need to upgrade to flotation. If we use the second process then we have to upgrade now.
so there is no cumulative process that will produce 55% as you are trying to infer.
