The 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. In the present, however, available ores are typically even lower in metal
