Abstract: The chromite ore in some place of Philippines belong to the low-grade refractory slope chromite sands with high content of iron. But this ore are slimed seriously, of which the ores are up to 69.73% -0.019 mm, so it is difficult to separate. Beneficiation tests on this sample are made. Chromium concentrate with Cr2O3 content of 44.15% and recovery of 34.23% is accessed from the raw ores with Cr2O3 content of 4.85% through the process of ore-washing, desliming and gravity separation. And the ratio of chromium and iron is 1.69. This process is simple, and it provides a new way to recycle this type of ore.
