Apatite microflotation using pequi oil: Mineral Processing ...
The white pulp does not have any commercial application being a residue. This paper proposes to use the oil from pequi's yellow pulp as a collector in apatite microflotation, due to its rich fatty acid composition. The oil was saponified with NaOH and then applied in microflotation tests using a modified Hallimond tube and pure samples of apatite.
Environmental impact of phosphate mining and beneficiation ...
in igneous rocks. Apatite is commonly very insoluble in its original state as extracted from the earth and is practically unavailable as a plant phosphorus source. 7 For this reason, drastic chemical processing with strong acids (such as Sulfuric acid, phosphoric or nitric acids) is necessary to produce soluble phosphate products. By virtue of
