The invention relates to a cleaning device, in particular to an ore cleaning device used in the mining industry. The invention aims to solve the technical problem of providing the ore cleaning device used in the mining industry which is simple in operation, high in cleaning speed and thus high in working efficiency, can collect waste water after cleaning, and thus does not affect the ambient environment. For solving the above technical problem, the invention provides the cleaning device used in the mining industry which comprises a bottom plate, a first collection frame, support rods, a baffle plate, a material discharging hopper, a second collection frame, a first electric reeling wheel, a first pulling wire, a torsion spring, a cleaning tank and the like; the top part of bottom plate is sequentially provided with an air cylinder, the first collection frame, the support rods, the first electric reeling wheel and the second collection frame in a bolt connection mode from left to right; and the air cylinder is vertically arranged. By adopting the ore cleaning device, the effects that operation is simple and convenient; cleaning speed is high, and thus working efficiency is high; and the waste water can be collected after cleaning, so that the ambient environment is not affected.
