Copper Flotation
A Copper Flotation Flowsheet. Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation. In general most operations of …

copper produced in the United States originated from flotation (Daniel E. Edelstein, Copper Commodity Specialist, U.S. Geological Survey, written commun., March 20, 2012). Copper sulfide ores must be concentrated before they can be economically transported to a smelter. Froth flotation is part of a copper beneficiation process in which finely ...

What is Flotation Process in Mining Industry?
The mixed flotation process is a commonly used process in the flotation of polymetallic sulfide ores. First, all the useful minerals are mixed and floated, and then the useful minerals in the mixed concentrate are separated one by one. This process is suitable for useful minerals grade comparison. Low (more gangue content) and useful minerals ...

Minerals | Free Full-Text | Flotation and Tailing Discarding of Copper
The mineral composition of copper–cobalt ores is more complex than that of copper sulfides, and it is also difficult to discard tailing efficiently in primary flotation for the fine-grained disseminated of ore. In this work, a mineral liberation analyzer (MLA) was employed to study the characteristics of minerals. As a significant mineralogical …

Separation of Copper-Nickel by Flotation and Magnetic Methods
At the INCO (International Nickel Co.) operation in Sudbury, Ontario, further separation of nickel from copper is accomplished by application of mineral dressing techniques to slow-cooled nickel mattes. These mattes contain about 50 pct Ni, 30 pct Cu, 20 pct S, and <1 pct Fe. They consist of grains of chalcocite (Cu2S) in a matrix of ...

Selective Flotation
I need to restate I suppose that flotation is a process of concentration in which we must put has much metal as possible into as little mass as possible. On the below Chart, selective flotation (separation) is obtained from the green line (1% mass) to the red line (4.5% mass). After >4.5% mass, you get mass pull, just mass.

GOLD RECOVERY BY FLOTATION. A test on a sample, crushed to pass a screen of 120 holes per linear inch, containing $37 gold and 4.8% copper, gave a recovery by flotation alone of 90% of the gold and 98.5% of the copper, but left $8 gold in the tailing. The concentrate carried 44% insoluble matter, which could be reduced by re-treatment.
