SOURCE: How to Unscrew SLIK tripod head from the rest of tripod?

Below the tripod head you will see what looks like a "sandwich" of two chromed pieces of metal.  The lower one is the top of the tripod's center column.  The upper one is the bottom of the tripod head. Using wrenches or other tools, unscrew the upper one counterclockwise to separate it from the lower one. There is a 1/4" threaded stud which holds them together.
If you plan on replacing the head with a pro head like a Manfrotto, you will need a reducing bushing.  Most heads expect a 3/8" stud, and this tripod's thread is a standard 1/4" stud. The adapters are available through Wolf, Adorama, B&H, and the like.

Hi there, welcome to FixYa.

That screw is just screwed into the top plate. Just unscrew it. If it's really difficult, you can use a pair of pliers to hold the screw, then turn the pliers. - Make sure you don't damage the threads that screw into the camera. You can help prevent this by using a cloth like a t-shirt. The cloth will help prevent damage incase you have to grip it hard. Just remember to be carefull.

Thanks for coming to FixYa.

- the part was cheap but the shipping was too high in my case. Good luck.

Hope you figured it out by now, but I just purchased a used SLIK U212 and was having some difficulty with the quick release. In the picture, it appears that your quick release is upside down in the hole. Release the tab and turn your tripod over to dump out the quick release mount.
