The German Oilfloc Process was developed to treat the high-clay, −400-mesh fraction of coal, which is the product of flotation feed desliming. In the process developed by the Central Fuel Research Institute of India, coal slurry is treated with diesel oil (2% additions) in mills and then agglomerated with 8–12% additions of heavy oil.

The study of the flotation of copper and molybdenite ores indicates that the recovery of molybdenite and copper flotation is reduced in the coarse, fine and very …

A. Gupta, D.S. Yan, in Mineral Processing Design and Operation, 2006 16.3 Flotation Circuits. Flotation is carried out as a continuous operation in a series or bank of cells. This increases the floating time, allowing ample opportunity for particle-bubble attachment to occur. The residence time of particles in the bank of cells range from 5 to 15 minutes.

Batch flotation tests were carried out on samples milled to 80% –75 μm at a slurry density of approximately 30% w/w solids. Synthetic plant water was prepared using distilled water modified by addition of ionic salts to achieve the ionic strength typical of process water at concentrator plants (Wiese, Harris, and Bradshaw, 2005).

For industrial flotation foam image processing, accurate bubble size measurement and feature extraction are very important to optimize the flotation process and to improve the recovery of mineral resources. This paper presents an improved algorithm to investigate mineral flotation foam image segmentation for mineral processing.

Flotation has been at the heart of the mineral processing industry for over 100 years, addressing the 'sulphide' problem of the early 1900s, and continues to provide …
