The gold mining ship is a comprehensive equipment with both mining and beneficiation systems. The washing machine screen, chute, jig, shaker and Other equipment equipped on the ship can form a relatively complete beneficiation process. The following is a description of several gold selection processes applied on domestic gold mining vessels:
(1) Single fixed chute process: consisting of a washing tank screen and a fixed chute (Fig. 1). The fixed chute is used for both rough selection (transverse fixed chute) and sweeping (longitudinal fixed chute).

(2) Fixed chute - jigging process: rough selection by fixed chute and jig sweeping (Fig. 2).

(3) Chute-jigging-shaker process: use fixed chute rough selection, jig sweep selection, shaker selection (Fig. 3), such as Huichun gold mine 250 liter gold mining ship.
