Abstract

Procedure for the obtaining of a mineral phosphate, whose organic matter is transformed in carbon by heating. Consists of the heating of mineral phosphate at temperatures of 380 to 600gc, in the presence of air, and in a continuous process, whereas, at least part of the organic compounds contained, are transformed in carbon, easily separable in the process of purification through filtration. This mineral phosphate is suitable for the obtaining of phosphoric acid via humid. R (Machine-translation by Google Translate, not legally binding)
