Harvesting of Spirulina platensis by cellular flotation and growth ...

Aim: To investigate an effective harvesting method for Spirulina platensis. Methods and Results: Eighty per cent of S. platensis cells in the logarithmic growth phase were harvested by flotation when the cells were set in a static condition for 2 h. The optimum harvesting time was about day 6 of cultivation. The flotation activity of S. platensis cells was enhanced by the addition of NaCl.

His design adapts the eponymous Jameson Cell he patented in the late 1980s. In contrast to the HydroFloat, his cell treats fine and coarse together. The flotation feed cycles past an airjet first, where it encounters the high energy useful for attaching fine particles to bubbles. "That's like the Jameson Cell, actually," he said.

Jameson cell - Wikipedia

The high intensity of the Jameson Cell means that it is much shorter than conventional column flotation cells (see Figure 1), and it does not require air compressors to aerate the suspension of ground ore particles and water (known as a slurry or pulp) in the flotation cell. The lack of a requirement for compressed air and the lack of moving parts means that power consumption is less than for ...

Copper Flotation - Mineral Processing & Metallurgy

A Copper Flotation Flowsheet. Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation. In general most operations of this type have two or more parallel ...

From coal mines to gold mines

Flotation cells separate minerals and met- als from raw material. Measuring the inter- face in this process between froth and pulp levels is critical for desired mineral/ metal extraction rates. One transmitter measures the level of the froth and a sec- ond measures the level of the interface using a reflector plate.

Principles of Flotation | Engineering360 - GlobalSpec

Flotation is a physico-chemical separation process that utilises the difference in surface properties of the valuable minerals and the unwanted gangue minerals. The theory of froth flotation is complex, involving three phases (solids, water, and froth) with many subprocesses and interactions, and is not completely understood.

And, assuming an average diameter of 2 µm, these cells could be packed into a plank-sized volume with dimensions 7 cm thick, 30 cm wide, and long enough to extend from the earth to the moon (386,000 km)! Assuming that the cells divide once per day, the oceans produce another plank each day.

Model Predictive Control for Froth Flotation Plants

Froth flotation is a common method to extract a certain type of mineral from ore while depressing the amount of undesired minerals in the extracted concentrate. It is done by adding certain chemical reagents to selectively rendering the desired mineral hydrophobic. In a flotation cell, air bubbles then lifts the mineral.

no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.

Report on flotation pilot plant design and arrangement - Intmet

To achieve an adequate flotation, bubbles that rise to the top of the flotation cell must not break until they are skimmed off to collect the floated particles. This is the reason why non-ionic surfactants are usually added to produce the desired stability of the froth. This may happen that a collector can act as a frother, such is the case
