Xinhai Mining Technology and Equipment Inc. undertook  the iron ore processing experimental research in Philippines, aiming to provide  scientific basis for the mineral processing plant design as technical basis for  future site production.


The ore contained Cu of 0.15%, S of 5.59% and Fe of  43.47%. It was polymetallic refractory ore with close dissemination  relationship of S & Fe and fine dissemination particle size. Metallic  minerals in the mine mainly include chalcopyrite, pyrite, pyrrhotite, etc. The  main gangue minerals were quartz, chlorite, calcite, mica and some clay  minerals. The relation between sulfide minerals and oxide minerals was very close,  which caused the difficulty of mineral liberation. According to the  characteristics of the ore, the process program "obtaining iron rough  concentrate by stage grinding & stage low intensity magnetic separation and  desulfurize the iron rough concentrate by flotation" was adopted. As a  result, the iron concentrate with Fe content of 68.93%, S content of 0.82% and  Fe recovery rate of 69.32% and sulfur concentrate with S content of 33.69% were  gained. The copper concentrate with Cu content of 13.03% could be obtained by  the comprehensive recovery of the magnetic separation tailings.
