How does devaluing a currency affect that country's ...

The main factor at work when a currency is devalued is that export prices go down for the foreign buyers, and imports get more expensive. For an example, let's use trading between Canada and the US. From a Canadian point of view, if the Canadian dollar is devalued from C$1 = US$1 to C$1 = US$0.5, then the hockey stick costing C$20 got its price slashed from US$20 to US$10 (= C$20 x US$0.5/C$1).

Froth Flotation Process - Mineral Processing & Metallurgy

The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles.
