History of Flotation PatentsKnow More

This is the part of the subject of which we have heard the most indeed until recently the literature of the flotation process was closely identified with the records of patent litigation That is why the scientific principles are as yet so little understood and the technology of the process has made such scanty progress The aim of a patent specification is to disclose just enough to prove...
