Tungsten Resources and Potential Extraction from Mine Waste This review is very interesting and informative for waste recovery from existing and old tailings dams/ponds.
This report missed one part that Almonty has on the others.

As we know the bigger the Gold Nugget or Diamond the better, huh ?

Of course the Gold Nugget was melted down and in todays terms an investor would pay big bucks to buy it intact, but would you break down a big Diamond to make little ones ?
So when it comes to Tungsten, big chunks are not the best result required, but big deposits are.
The reason for Primary, Secondary, Tertiary Crushers, plus Ball and Rod Griinding Mills is to reduce the partical size of the product for the client.
GDP ? That last letter stands for "Powder", not chunks.
Now, going back to the start, the report talks about all the many processes involved to extract Tungsten and they do mention Almonty mines many times.
The main part that is missing in this report is that Almonty has now paid for the tech from KIGAM (2 mill I think) to use the new flotation system that does not need to boil the soup at such high temps or use too much bad chemicals. Sangdong does not need tailings dams/ponds at all.
This will apply for the older mines as well soon.
It's all about smarts.
