A method for selecting chromium in lateritic mines, which comprises classifying laterite ore pulp by a first-order hydrocyclone to obtain classified underflow and graduated overflow; roughening the graduated underflow using a spiral chute to obtain heavy products and light products; Concentrating the heavy product with a shaker to obtain a rock concentrate rough concentrate and a rock concentrate light product; and performing magnetic separation on the rock concentrate concentrate using a magnetic separator to obtain the magnetic concentrate and the magnetic concentrate. The method of chromium removal of laterite ore according to the present invention can improve chromite
