Selection of ore particle size during leaching

Generally, around 80% at 200 mesh is sufficient
Reply to 2# Pfz2867: Is it easy to filter at 200 mesh?
Let’s determine it through experiments! From the perspective of leaching, of course, the smaller the particle size, the larger the surface area, and the faster the reaction! But there will be some issues with subsequent settlement and filtration!
Reply to 4# wuhedong: Yes, in theory the smaller it is, the better – but factors such as filtration that follow need to be taken into account.
90% of 100 models use Xingyuan filter presses; it’s also possible to use other ones
Under normal circumstances, it is required that 100 mesh be fully passed after ball milling, and over 80% should pass through 200 mesh.
