Advanced System for Control Milling and Flotation ...

The main reason of mineral processing fluctuations is a mixing of ores from various sections of a deposit. Instability and non-optimized parameters of milling and flotation take 3% to 6% of losses of valuable component. Milling and flotation process are characterized by considerable fluctuations of all input, output and intermediate parameters.

Mineral Processing - an overview ScienceDirect Topics

Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.

A review of froth flotation control - ScienceDirect

2011-9-14  Advanced flotation control. AFC, also known as stabilising control, aims to reject the effects of input disturbances (e.g. a change of ore type) and maintain the flotation process as close to steady state as possible (McKee, 1991, Laurila et al., 2002). This is generally achieved by controlling mass pull; recycle load; stream grade and/or ...
