    Sep 30, 2019 “The first stage is known as rougher flotation; after that, the ore goes through a further six stages of cleaner flotation. The cleaner tailings are reground and re-floated. This product joins the mainstream acidspar circuit. The re-float tails and first cleaner tails are processed and used to produce Metspar, a lower-grade fluorspar product.
