Sesame seeds contain more foreign substances than ordinary stones.
If you use a sieve that has a hole larger than sesame seeds, put sesame seeds in it and shake it off, you can remove some of the bigger foreign substances.

In addition to the top story...
If you put sesame seeds in water, the sesame seeds are light, so they float in water.
If you scoop it out with a mesh like cooking, you can pick out heavy foreign substances.
You can sort out things like stones like this.

The foreign substances in sesame seeds have similar weight and properties to sesame seeds, so it's hard to pick them out.
There's no other way.
The answer is to pick one by one.
