The Importance of pH in Flotation

Like all the reagents, depressants are only selective and effective within limited volume range. Too little reagent and the unwanted mineral will begin to float, too much reagent and the wanted mineral will begin to be depressed. The simplest modifiers are pH control chemicals. The surface chemistry of most minerals is affected by the pH.

From Ore to Finished Product

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
