How Froth Flotation Works - Mineral Processing & Metallurgy

To start with I will give you a simplified description of how selective froth flotation works, lets start over again with a description of the equipment and why it works. When the grinding circuit is finished with the ore it will be ground very fine and the density of the slurry will be between 30% to 45% solids. This is very important because the slurry will be treated chemically and air will ...

InflationData: Is gold really a hedge?

But how well does it really work? For those who argue that Gold is an inflation hedge all they have to do is look at the chart at the right and they will see that it is not a perfect (or even imperfect) inflation hedge. Simply put if Gold were truly a perfect inflation hedge the red line in the chart would be perfectly flat.
