What is a Mill and how Big should it be?
Milling is about taking the sorted crushed, mineralized rock from the Mine, and making into a slurry so we can float the minerals off. How do we do that.
First we put it into a ball mill for a first mill, the size we want to float we send straight to the float cells, anything larger, then we regrind it to the size we want for the float plant, and send it on its way, etc.
A 100 and 200 ton a day mill is actually quite large, as there are a lot of rocks we have to grind to fine beach sand size, so why is ours so small?
At the Mine, we sort the rocks to get rid of all non-mineralized material, and one would be surprised to see how much of that is mined, The ore-sorter obviously eliminates a lot of that, but there is material that holds a lot of mineralization that bypasses the Ore-Sorter, so our milling floating capacity is geared to that, or a maximum 50 ton/day
