Plant data for a perfectly mixed cell relates recovery using: (4) R (t) = ∑ i = 1 n m i k i τ (1 + k i τ) where τ = the residence time for the cell or bank of cells being considered Both these equations require the recovery of the target mineral to be known, usually on a sized basis, which in the case of an industrial circuit, would require a plant The design of cellbased flotation circuits is often completed in two distinct phases, namely circuit structure identification and equipment sizing selection While recent literature studies have begun to address the implications of stochastic analysis, industrial practice in flotation circuit design still strongly favors the use of deterministic Minerals Free FullText Design of CellBased Flotation Circuits
