Copper-Molybdenum ores

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.

Introduction to Mineral Processing

A copper collector may also be added at this point The pulp progresses to the flotation cells The frother and copper collector are usually added to the pulp just before the roughers Additional copper collector is often added to the scavenger flotation cells and may be added at several other points.

Factors Influencing Copper Ore Flotation

Copper ore is the mineral mixer containing some copper which could be concentrated by present technology Sulfide copper is the most common raw material used in mining process plant, because it has a better floatability Compared with other minerals, there are much more factors influencing copper flotation process In order to increase copper.

Copper activation option for a pentlandite-pyrrhotite

Introduction Different sulphide ores respond differently in the prospect of copper activation to thiols for froth flotation With the BCL Selebi-Phikwe ore body, pentlandite-pyrrhotite-chalcopyrite co-occur and there is the constraint of fine pentlandite dissemination in the pyrrhotite, so that liberation is limited.

Copper Mining and Processing: Processing of Copper Ores

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 9999% pure copper called cathodes, which will ultimately be made into products for everyday useThe most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different.
