Claim Text:
1. A simplified valuable mineral sorting apparatus which collects valuable minerals from clastic resources such as crushed rock powder, sea sand or river sand, the apparatus comprising: a first storage tank which accommodates therein a mixture composed of water and heavy powder and includes a specific gravity measurement module for measuring a specific gravity of the mixture; a second storage tank which is disposed below the first storage tank and which accommodates a portion of the mixture exceeding a capacity level line indicated on the first storage tank; a first discharge tube, an end of which passes through a bottom of the first storage tank and is connected to a upper part of the second storage tank such that the excess portion of the mixture is introduced into the second storage tank and the other end of which is positioned at the capacity level line indicated on the first storage tank and is adjustable in height; a second discharge tube which is connected to a side wall of the first storage tank to discharge the mixture in the first storage tank outside and which includes a flow rate control module for measuring and controlling a flow rate of the mixture; a specific gravity sorting device which includes therein a sorting container for receiving the mixture discharged from the second discharge tube and which changes a slope of the sorting container to sort one of a heavy mineral, a medium specific gravity mineral and a light mineral from the mixture in the sorting container; and a control unit for controlling operations of the flow rate control module and the specific gravity sorting device.
