Unconventional column flotation of low-grade gold fine ...
2008-3-28 · A flotation column is a reactor composed mainly of a collection zone and a froth zone. The collection zone has the objective of attaching hydrophobic particles to bubbles and the froth zone is responsible for the carrying capacity and froth enrichment (Finch and Dobby, 1990, Dobby and Finch, 1991).The drop-back material from the froth returns to the collection zone, goes
