Industrial Tests to Modify Molten Copper Slag for
For all batches, the flotation experiments were carried out using a laboratory-scale flotation machine with a mechanical stirrer. Prior to each test, 500 g of the sample was wet ground in a ball mill to 90% passing 0.043 mm, and then the ground slurry was injected into a 1.5-L XFD flotation cell for froth flotation at the natural pH of the ...
