"Flotation Process" Today In Sci

The Flotation Process Until the invention of the flotation process, the extraction of metal depended upon being able to hand-pick the material in order to be economical. Taking copper as an example, previously, that meant that using low-grade ores with less than four percent metal content would not be practical.

2020-12-18 · 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
