Sequential multi-scale modelling of mineral

The sequential multi-scale method is then illustrated with reference to the mineral flotation process. In this case, multi-phase CFD (computational fluid dynamics) models of large-scale cells has been complemented by micro-scale CFD simulations of bubble–particle collision, and experimental and modelling studies of the bubble–particle ...

Handbook of Flotation Reagents ScienceDirect

Sequential flotation in industrial practice is used in cases where the copper in the head is much greater than nickel (4–5 times). Some of the processes that have been developed recently and are currently in use in a number of operating plants include nitrogen flotation and the application of high-intensity conditioning (HIC).

Review of flotation of feldspar: Mineral Processing

2018-6-8  The general circuit for commercial separation of feldspar consists of three sequential stages of flotation, all of which are carried out in an acid medium. Usually, before flotation, the feed is deslimed, removing any fine clay minerals present. In the first flotation stage, mica is removed with an amine collector.
