<p>The present invention relates to a metal screening apparatus for earth and sand comprising a raw material input part for inputting a raw material; an upper plate for discharging the raw material inputted from the raw material input part to below a diamond wire net and having flat iron connected to the top of the diamond wire net at a predetermined angle; a lower plate for screening metal from the raw material discharged from the upper plate; and a support frame installed and fixed to the ground, supporting the combination of the upper plate and the lower plate, and including a hydraulic device part for controlling the upper angle of the upper plate, wherein the lower plate includes a vibration device part for generating vibration; a plurality of diagonal walls arranged at a specific angle separated from an inner surface; opening and closing parts installed on the ends of the diagonal walls separately, and opening and closing to recover the metal screened from the raw material; and a discharge part for discharging raw materials except for metal. The metal screening apparatus for earth and sand according to the present invention can reduce processing time and enables accurate screening and separation because the process thereof for screening heavy metal and valuable metal from earth and sand including heavy metal and valuable metal, has higher efficiency of production than an existing process.
