FGB, septic1,

Great to have you writing your thoughts.

Just with your's FGB.

Slowing a wet spiral down doesn't really help with extracting the product you are chasing.

The main principle for a wet mill is gravity. Just think of running water down a slide, the less water (or feed) that goes down, the smaller the breakdown zones of the minerals. At the bottom of a spiral you have splitters, which are just little blades that zone off the area of mineral according to density (the heavier mineral on the inside, the lighter to the outisde). If the feed volume moves around then the splitters would need to be adjusted and this plant looks to have at least 300 spirals. It's normal practice to just get the flow right and then work from there.

If you are running the plant normally and the feed is hypothetically 100%HM, just imagine it coming down the spiral. It would be full width and you would be losing zircon, chromite etc., into the wide area of spiral that would normally be taking the silica (the rubbish). If you read the quarterly again, its says they did not produce garnet, which is really a silica sand. So I think the variability of the feed prior to entering the wet mill could well be the problem.

Suffocants - yes, changing the water tension would be advantageous, but most plants incorporate this into the feed and I would expect them to be using this already.

They'll sort it out, it just may take some time.
