'I'herieed-ing-Vmeans isdisposed toy deliver creto i v at the lower part of the table where it is tumbled under Water between baiiie plate 34 and the table and stratified, the values settling and the gangue rising. The rifies 16 pick up the values,

-elevating themand carrying them to the left on y the lower advancing side of the table where they are further washed and concentrated bythe ac' f tion of the spray means, and the rotating. table.

Eventually the concentrates are carried to the discharge opening 11 and delivered to anysuitable receptacle. The material in the riles is.l tumbled and the gangue onfthe top washed downwardly as the material is advanced to theleft Y with an upward urge. The material captured bed tween'the table and` baille' plate is thoroughly -f tumbled so asto yprecipitate the values. The baille plate prevents the material from-beingwashed over the'edge of the trough-before suiil-v cientv stratiiication takes place for 'efdcientac-- tion bythe rilesz The gangue is washed'over'theil trough through the clearance between the fol-f3 lowing edge of the bailie plate 34 and the troughf' Adjustment of the inclination of the table, the position and-'direction of the dressing water spray' and the relation of the baille plate `maybe mad'ef Y to accommodate thel concentrator to lmaterial off, various characters. VThe tailings" settle in tankv 113," the water passing'through overflow pipe 19-and made available for further use, resulting in econ-v omy of water consumption. The trough is an important feature of the invention as it retainsv the material long enough to insure eiiicient precipitation. Without means resisting travel over the edge of the trough, the material is Washed from the top/before suicent tumbling has taken place and a high percentage of values is washed with the gangue into the tailings tank.l

Figs. 3 and 4 show a modified form of table wherein there is a central bed 37 having spiral riiles 38 and a sloping rim 39 forming a trough. The rim 39 is provided with riies 40 which carry `the material inwardly thereby restraining it from quick passage over the edge ofthe trough and insuring retention for tumbling and stratification.

By proper design of the trough as to its extent'v and slope in the case ofthe modification shown in Figs. 3 and a, the baiile plate may be omitted from the rconcentrator and efficient recovery ob- "tained in certaincases particularly placer ground. The rim 39 spreads the'material aiding in the precipta'tionof values. By proper design of the trough shown in Figs. 1 and 2 Iespecially as` to the return flange 13 and'lip -14,the baille plate may also be omitted in treating certain material, the flange and'lip resisting travel of the material l over the edge of the trough.
