Celebrating 's 50th anniversary in mechanical flotation
Kennecott Copper Corporation. Bonneville Concentrator Rougher: 45 rows of 16 cells per row (Jeppson and Ramsey, 1976) In the past, flotation halls would house numerous smaller cells, typically around 1-3 cu.m in size, with multiple mixers in each row. In today's flotation operations, this number has significantly decreased.

MINERAL PROCESSING METHOD OF THE WEEK
Flotation is the most widely used method for the concentration of fine-grained minerals. It takes advantage of the different physicochemical surface properties of minerals—in particular, their wettability, which can be a natural property or one artificially changed by chemical reagents. By altering the hydrophobic (water-repelling) or hydrophilic (water …

Improving flotation energy efficiency by optimizing cell hydrodynamics
1. Introduction. Comminution of ore is the most energy intensive stage of mineral production and therefore improvements in comminution efficiency can result in significant energy savings (Duffy et al., 2015, Ballantyne and Powell, 2014).In contrast, for froth flotation, which is not energy intensive, optimization has traditionally focused on …

Regulation of bubble size in flotation: A review
Subsequently, bubbles collide with the mineral particles in the flotation cell, and the hydrophobic particles adhere to the bubbles, rising to form a froth layer, whereas the hydrophilic particles sink to the bottom of the cell to form a tailing [[11], [12], [13]]. The interaction process of bubbles and mineral particles is therefore considered ...
