It can be divided into metallic minerals and non-metallic minerals. The unit content of useful components in ore is called ore grade. Precious metal ores such as gold and platinum are expressed in grams per ton, and other ores are often expressed in percentages.

10. A method for using a ore screening device for ore mining according to any one of claims 1 to 9, characterized in that: The following steps are involved: First, the ore to be screened is added through the feed port (10) so that the ore enters the upper right side of the first screen plate (8), and at the same time, the bidirectional drive motor (804) is started to further drive the first rotating shafts (805) on both sides to rotate, so that the movable column (806) connected to the outside of the first rotating shaft (805) rotates in a circle, further driving the movable rod (807) connected to the outside to rotate, and the second screen plate (9) is caused to shake through the second rotating shaft (904); when the second screen plate (9) shakes, the second elastic plate (902) on the outside of the second screen plate (9) drives the bottom of the first screen plate (8) to shake, so that the first screen plate (8) shakes through the first elastic plate (802) on the outside, and then the ore on the first screen plate (8) is screened layer by layer through the screening slot, and at the same time, the electric motor is started. The machine (506) drives the first rotating rod (501) to rotate through the motor (506), further drives the first gear (503) to rotate, and drives the transmission gear (505) to rotate, and drives the second gear (504) to rotate through the transmission gear (505), and further drives the two sets of driving rods (508) below to rotate, and drives the third rotating rod (5081) to rotate, so that the two sets of sliders (5082) slide evenly inside the slide groove (512), so that the adjustment plate (511) rotates intermittently, and at the same time drives the lower dividing plate (7) to rotate through the connecting column (513), so as to divert the ore on the first screen plate (8), and finally, the screened ore finally falls on the conveyor belt (12) at the bottom, and the screened ore is transported by the conveyor belt (12).
