·In this process if apatite crystallizes earlier than feldspar and other minerals the Sr and REE contents of apatite will be relatively high Thus changes of Sr contents and REE ratios La/Yb N La/Sm N and Sm/Yb N in apatite might indicate the process of magma evolution Pan et al 2016 Xing et al 2018 Zhang et al 2019
·When recycled water containing high levels of dissolved salts and metal ions is used in the process of apatite flotation the recovery and P 2 O 5 content can be seriously affected Large consumption of flotation reagents also restricts the sustainable production of mines Dong et al 2021; Huang et al 2019
The crystal structure and chemistry of apatite results in relatively high mineral melt and mineral fluid partition coefficients for many trace elements Hughes and Rakovan 2002; Pan and Fleet 2002; Prowatke and Klemme 2006 Calcium a large cation has two structural sites in apatite Ca1 and Ca2 which are capable of accommodating high concentrations of many trace

·The process of sulfuric acid roasting water leaching is a traditional technique used to extract REEs from monazite Fig 11 100 In this process monazite is roasted with concentrated sulfuric acid and its phosphate structure is destroyed Eqs 14 and 15
·The Tongchang mine is the largest mine in the Dexing deposit and it has the most complete alteration zoning To better constrain the petrogenesis magma conditions and hydrothermal alteration process three samples of granodiorite porphyry with varying degrees of alteration were collected based on fieldwork observations from different locations in the
·Apatite is a nearly ubiquitous accessory phase in igneous rocks that crystallizes during the entire magma evolution process and has great implications for geochronology and petrogenesis Previous studies suggested that Nb Ta mineralization in the giant Renli deposit was genetically related to Late Jurassic two mica monzogranite or Early Cretaceous muscovite
