Abstract: In order to promote the industrial test of a coastal zircon-titanium placer in Mozambique， the process mineralogy of chemical composition，particle size composition and beneficiation process charac⁃ teristics of valuable minerals were studied. The results show that there are many kinds of valuable minerals in the ore sand，mainly includ ilmenite，zircon，rutile，iron-bearing rutile and monazite. Due to the vari⁃ ety of valuable minerals and complex physical properties，it is difficult to separate them. The particle size of sand in the ore sand is mainly 0.10~0.50 mm，and the particle size of valuable minerals is mainly -0.30 mm，which is finely distributed，with uniform particle size and narrow particle size range. The valuable minerals in the ore sand have good natural dissociation，and the target minerals such as ilmenite，white ti⁃ tanium，rutile，zircon，and monazite are basically single particles，which can be separated without grind⁃ ing.
