· This can be accomplished by the study of several types of objects (minerals, fluid inclusions, etc.) associated with mineralization. Apatite (Ca 5 (PO 4) 3 (OH,F,Cl)) is an ubiquitous accessory phosphate mineral found in many types of rocks and environments. This is particularly true with regards to ore deposits.

· The igneous apatite (F-rich) is the omnipresent accessory mineral found in almost all igneous rocks, from mafic to felsic, although 0.11 vol% of the rock is in the more normal range []. However, some peculiar igneous systems can often lead to economically valuable accumulations of apatite (concentrations > 3–5 vol% of the rock) [ 2 , 50 , 51 ].

· Aqueous Sulfuric Acid Dissolution. The mechanism of phosphate leaching with aqueous sulfuric acid is fairly well understood. The reaction occurs in three steps: (1) Sulfuric acid dissociates forming H+ ions and SO4²- ions in the solution. (2) The H+ ions attack the apatite particles dissolving Ca²+, CaPO4-, and PO4³- ions into the solution.
