No one owns it. This patent was issued on Jun 19, 1962. It would have expired in the 1970's.

You can easily search for patents on Google Patents using their publication number.

See Google.com/patents/us3039165 (it even has a link to this page):

Method and apparatus for production of lightweight aggregate from dust

Publication number: US3039165 A

Publication type: Grant

Publication date: Jun 19, 1962

Filing date: Apr 28, 1954

Priority date: Apr 28, 1954

Seems like it used to be owned by Solite Corp, but old patents expire 17 years after grant or 20 years from filing, whichever greater. This means that everyone has been free to use it since 1979.
