Mining waters from active or closed copper mines can contain up to ca. 1 g/L of copper, while the iron concentration is up to ca. 2 g/L due to e.g. bacterial leaching of sulfide copper and iron minerals (Gorgievski et al., 2009).On the other hand, metallurgical process wastewaters can contain a wide range of elements, such as Cu, Fe, Ni, Zn etc. depending on …

Column flotation cells, like mechanical cells, are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Instead, mixing is achieved by the turbulence provided by the rising bubbles. Columns are mostly used to produce final grade concentrates because they are capable of high selectivity.

However, the high turbulence in the RFC's downcomer dispersed kaolinite aggregates, potentially reducing kaolinite entrainment. Despite the dispersion of kaolinite aggregates, the entrainment of kaolinite could still be high in a conventional flotation cell given the fine size of kaolinite particles.

The demand for copper is ever-increasing, playing a critical role in the transition to a clean-energy economy. By the early 21st century, most of the rich copper oxide ores had already been mined out, leaving current deposits with a grade sometimes less than the tailings of earlier mining [1,2].A study conducted by Calvo et al. [] revealed that the average copper …

Copper sulfide ore is an essential copper resource for the extraction and production of copper metal. Generally, most copper sulfide ores contain pyrite (FeS 2).Thus, the flotation of valuable copper sulfide minerals usually requires the rejection of pyrite to produce a high-quality copper concentrate, which is commonly called "Cu-S separation".

Thirty years ago, a cell 30 cubic metres in volume would have been unusually large. Now, 300-cubic-metre cells are commonplace. Outotec has a 500-cubic-metre cell in operation and several 630-cubic-metre cells in delivery, while FL has one 660-cubic-metre cell in operation. Building one big tank does provide energy economies of scale.

The Jameson Cell consistently produces fine bubbles and intense mixing between air and slurry. This means fast, efficient flotation. While the principle of using air bubbles to recover particles is the basis of the technology, it is the way air bubbles are generated and how the bubbles and particles interact that make Jameson Cells unique.

The froth recovery unit is tailored for use of wash water and for high solids flux. Efficient particle collection and high froth recovery translate into fewer, smaller cells, resulting in a smaller footprint and building height, with lower power consumption, and the potential for good selectivity in both roughing and cleaning applications.
