Apr 12, 2012· The present invention, named Bunge/Fosfertil process, is applicable at different lithologies of phosphate ore with carbonated-silica matrix from igneous and sedimentary sources, i.e., consists of comminutioning the ore by crushing, homogenization, milling and disliming, prior to the apatite flotation.
Phosphate ore is the most important source of phosphorus in fertilizers. To supply the phosphoric acid plant with phosphate, a high grade of phosphorus is essential, as well as reduced levels of impurities such as magnesium, iron and aluminum oxides.

In the presence of NaCl apatite was found to be depressed without any significant effect on the flotation of dolomite. In order to achieve maximum separation of dolomite single mineral tests were conducted to determine the optimum pH, salt and collector concentration.
The major operating difference between column flotation cells and mechanical flotation cells is the lack of agitation in column flotation which reduces energy and maintenance costs. The practice of froth washing in direct flotation increases concentrate grades without significant recovery losses.
"PROCESS FOR OBTAINING APATITE CONCENTRATES BY FLOTATION", according to claim 3, characterized by using the carbon dioxide gas in all steps of the flotation or only in the cleaning stages, "cleaner" and "recleaner", always insufflated in flotation cells through suitable mechanisms for this aim.
Brazil has many mineral resources, one of them being phosphate rocks. Established in 1978, the current main mineral-processing route for the Brazilian phosphate rock igneous deposits consists in a direct flotation using alkaline-saponified fatty acids as collector.
selectively depress the flotation of apatite, thus realizing the separation of apatite from dolomite. Further, ... 2.0 g of pure mineral was placed in the flotation cell with 35 mL deionized water and then conditioned for 1 min. NaPP and NaOL were successively added and stirred for 3 min, respectively.
The synergistic effects between sodium dodecyl sulfonate (SDS) and a mixed fatty acids collector for apatite flotation were investigated. SDS benefitted the apatite flotation at pH 9.5. The TOC measurements showed that the addition of SDS improved the surfactants adsorption at the apatite …
