Flotation (von englisch to float – schwimmen) ist ein physikalisch-chemisches Trennverfahren für feinkörnige Feststoffe aufgrund der unterschiedlichen Oberflächenbenetzbarkeit der Partikel. Das Verfahren findet in einer Flüssigkeit, häufig Wasser, und unter Zufuhr von Gas, häufig Luft, statt. Laut Definition gemäß VDMA-Einheitsblatt 24430 handelt es sich um ein Trennverfahren, bei ...

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

As shown in Figure 7-104, raw (or pretreated) wastewater receives a dose of a chemical coagulant (metal salt, for instance) and then proceeds to a coagulation-flocculation tank. After coagulation of the target substances, the mixture is conveyed to the flotation tank, where it is released in the presence of recycled effluent that has just been saturated with air under several atmospheres of ...

Westpro currently supplies two lines of flotation equipment-tank and conventional cells. Completely redesigned in 2012, its 10-model tank cell line-up offers sizes from 20 m 3 (700 ft 3) to 300 m 3 (10,600 ft 3). Its conventional cells are available in nine models from 0.014 m 3 (0.5 ft 3) to 14 m 3 (500 ft 3).
The results showed that the surfactants can significantly improve dolomite flotation performance by increasing collecting ability and tolerating the effect of calcium ions and slime contents.;The stirrer-tank cell batch flotation tests were carried out using two natural high magnesium phosphate ore samples containing 3.3% and 1.5% MgO. The test results showed that the surfactant DP could ...

Of all the methods of extracting gold & processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets. This page offers a comparative review of gold recovery ...
Flotation depends on the fact that the grains of some minerals, and especially of metals, differ in the degree to which their surfaces can be wetted by a suitable solution. The powdered product of grinding the ore is fed into a series of tanks called flotation cells which are filled with a solution containing various oils capable of forming a froth. Air is pumped into each cell, the solution ...

Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.
Because the key parameters of flotation process are difficult to measure on-line, and the size of ore particles produced by raw ore grade and grinding fluctuates in a large range, it is difficult ...
