What you should have admitted is that you didn't have the intelligence to understand what I was saying and I may not have agreed until your last post. I think you should examine your own abilities before questioning mine.
I didn't comment on your 80% because on page 25 it states:
"Target combined wet & dry plant recoveries of >70%"
Why would I use your totally arbitrary figure of 80%?
I was trying to be polite and ignored your arbitrary figure.
Now let's go over it again.
The wet processing takes the alluvium to wet processed ore. The ratio of which can be calculated by dividing the final grade with the initial grade. Like this:
12/.03= 400 and 8/.05= 160
Get it?
Therefore, as I said 400 tonnes of 0.03% TREO Alluvium will be needed to produce 1 Tonne of 12% TREO wet processed ore. etc...
You must do this calculation for each of the permutations to then work out the amount that will need to be dry processed. Only then can you work out the costs for both the wet and dry processing for each permutation because the amount of wet processed ore will be different for each grade, both initial and final.
Of course you will need to do similar calculations to above because the concentrate is ~40%. not 100%.
The final step is to discount the recovery rate after the calculations for both the wet and dry processing.
Let's use your figures:
18Mt x .04% = 7200 t Treo
Let's say that is at a wet processed grade of 8%.
Then (7200/8)*100 = 90,000 will be the amount of wet processed ore to produce the 7,200 tonnes gross.
May I suggest a grade of 0.03 will require more tonnes of wet processed ore.
I know I make mistakes but think before you make such defamatory statements because it just might reflect on your intelligence more than the person you are slighting.
Not this time Ausheds but good try.
