Understanding ORP: Oxidation Reduction Potential

2016. 12. 2.  ORP is measured by a probe in a small sample of flowing water, usually next to your chemical controller. An ORP sensor consists of an ORP electrode, and a reference electrode. Basically a signal is sent between them which determines your oxidation and reduction potential. The rate of electron transfer is measured in mV and read as ORP.

Recovery of copper is by standard flotation reagents identified in the copper ore flotation description. Molybdenum will float naturally with the copper but can be crowded in the froth by the copper mineralization and use of a moly collector (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) enhances its floatability.
