Although industrial mineral flotation operation commenced at the beginning of the 20th century the role of flotation kinetics was not considered until 1948 when sutherland derived the first particlebubble collision model 18 based on single individual particles encountering a single rising bubble under potential flow regime since then numerous particlebubble collision and attachment
A typical copper operation contains many flotation cells often with a ph sensor in each cell the number of sensors and their locations are largely dependent on solution chemistry and vary from plant to plant sensor life and maintenance quickly become important economic factors the ph sensor in any mineral processing slurry should be
Specialised flotation cells from conventional to column flotation technologies are available including flash flotation cells prioritised assay turnaround provides near realtime results allowing operating parameters to be optimised and alternative reagent schemes trialled during continuous operation pilot scale flotation can also be performed

Flotation of various minerals such as feldspar quartz calcite potash barite phosphate fluorspar etc is carried out using the chemicals direct and reverse flotation are the two flotation methods depending on the attachment manner of the mineral froth flotation chemicals play a major role in the mining and processing of mineral ores
A froth flotation cell consists typically of a collection zone or pulp zone located below the feed particle point and a cleaning zone or froth zone above the particle feed point 26 figure 2 the collection zone is fed backstream by the pulp pushed by the bubble swarm created by a gas sparger at the bottom of the flotation cell
