Abstract


Taking into account that phosphate rocks can have high solubility regarding the different kinds of solvents used, dissolution of apatite from different places was applied in 2% citric acid solution. Semi analytical, 0,001g resolution scales for quantifying mass were used as well as Stolhman bottles attached to Wagner-like agitator where the extraction was carried out. Also, a digital spectrometer for doing the reading which determines the phosphate grades was used. The results consisted of a minimum value of 0,33% and a maximum of 28,2% of P2O5 varying according to the origin of the milled samples. The result can be useful for the selection of rocks to be processed.
