Flotation Depressants - Mineral Processing & Metallurgy

First let's change the amount of the Flotation Depressants used. The valuable mineral that isn't liberated from the unwanted mineral will begin to be depressed along with the waste. For the floatation operator, the change that will become most apparent is, that the color of the froth will begin to reflect more of the wanted mineral's color. This is because the froth is becoming purer as ...

Mining and Extraction: Oxide Ores - processes for .

During the initial phase an organic solvent is used to recover copper ions contained in the pregnant leach solution, exchanging them with hydrogen ions in the acid. The final phase of the solvent extraction process employs a strong acid to strip the copper from the organic solution, producing a blue, enriched copper-bearing solution that is treated at an electrowinning plant.
