A Review of the Flotation of Copper Minerals
This paper reviews the literature on the recovery of the above mentioned minerals by flotation. The increasing complexity of ore deposits, declining ore grades and higher global demand for copper...
installation of its kind in the world. Also at an Antofagasta operation, Siemens has installed a second 16 m³ hybrid flotation cell at Minera Los Pelambres . In the molybdenum concentrator, it recovers fines lost by conventional flotation cells. Its benefits include: Increased molybdenum recovery by about 2%
reason, several papers on general flotation modeling, as well as literature on other processes from which model developers have derived fundamental relationships, are included in this review. 2.2 Background Flotation columns first appeared on the market in the late 1960s as an innovation in the field of froth flotation.

Flotation columns derive their name from the geometric shape of the vessel. Unlike conventional mechanical cells, column cells are tall vessels ranging in height from 25 feet to more than 50 feet . The surface area of a column cell is smaller than that of a mechanical cell which helps to promote a stable and deep froth.
The aim of this literature review is to broadly explore the various control strategies that have been/are being, developed and utilised from a metallurgist39;s perspective. This work shall begin with a look at the key variables and considerations in the control of flotation.
