Our objective was to evaluate whether an acidic mine waste (AMW) could be used beneficially by reacting it with sparingly soluble phosphate rocks (PRs) to produce more soluble P fertilizer materials. Three PRs from Brazil and Peru were reacted with different concentrations of AMW. Changes in mineralogy and P species were determined using a combination of X\u2010ray diffraction and phosphorus K\u2010edge XANES spectroscopy, in addition to extractable P concentrations. Increasing the AMW concentration typically increased extractable P. X\u2010ray diffraction data showed transformation of apatite to other species when PRs were reacted with AMW at \u226550% (v\/v) in water, with gypsum or anhydrite forming at AMW concentrations as low as 12.5%. Linear combination fitting analysis of X\u2010ray absorption near edge structure spectra also indicated a progressive transformation of apatite to noncrystalline Fe(III)\u2010phosphate and more soluble Ca\u2010phosphates with increasing AMW concentration. Because this AMW is costly to dispose of, reacting it with PR to produce a higher\u2010grade phosphate fertilizer material could decrease the environmental impacts of the AMW and diminish the consumption of pure acids in conventional P fertilizer production.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Core Ideas<\/jats:title>\n                    <jats:p>\n                      <jats:list list-type=\"bullet\">\n                        <jats:list-item>\n                          <jats:p>Reusing fertilizer production waste can lower its environmental impact and enhance crop production.<\/jats:p>\n                        <\/jats:list-item>\n                        <jats:list-item>\n                          <jats:p>We evaluated products of acid mining waste reacted with phosphate rocks.<\/jats:p>\n                        <\/jats:list-item>\n                        <jats:list-item>\n                          <jats:p>Chemical speciation analyses indicated conversion of apatite to more soluble phosphates.<\/jats:p>\n                        <\/jats:list-item>\n                        <jats:list-item>\n                          <jats:p>New P products have agronomic potential.<\/jats:p>\n                        <\/jats:list-item>\n                        <jats:list-item>\n                          <jats:p>Plant growth tests are needed to measure these P products\u2019 performance as fertilizers.<\/jats:p>\n                        <\/jats:list-item>\n                      <\/jats:list>\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.2134\/jeq2016.03.0079","type":"journal-article","created":{"date-parts":[[2016,10,27]],"date-time":"2016-10-27T17:16:45Z","timestamp":1477588605000},"page":"1988-1997","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Increasing Soluble Phosphate Species by Treatment of Phosphate Rocks with Acidic Waste"],"prefix":"10.1002","volume":"45","author":[{"given":"Wedisson O.","family":"Santos","sequence":"first","affiliation":[{"name":"Dep. of Soil Science Univ.
