The first pneumatic-flotation plant in this country was erected by me in February 1914 for the National Copper Company at Mullan, Idaho, a description of which has already been published. The results were fully up to expectations from the very start. This plant consists of 8 rougher and 2 cleaner cells and treated 500 tons per 24 hours.

This explains why, in order to smelt 4 million tons of new copper in 1963, nearly 400 million tons of ore had to be handled and treated in various ways. Flotation depends on the fact that the grains of some minerals, and especially of metals, differ in the degree to which their surfaces can be wetted by a suitable solution.
17.7 Flotation of Gold-Containing Copper Ores. The floatability of gold from gold-containing copper gold ores depends on the nature and occurrence of gold in these ores, and its …
For example, it is estimated that for a plant processing 50,000 tonnes of ore containing 1% copper per day, increasing the copper recovery from 86 to 87% of that contained in the ore could increase revenues by approximately $4 million annually. This revenue increase, estimated from a value of $1.10/kg allowed for the copper content of the concentrate when the metal was selling …
In addition, froth flotation is suitable for the separation of fine particles that are difficult to recover by other beneficiation methods. Copper-lead ore has the characteristics of fine …
Although basic porphyry copper flotation and metallurgy has remained virtually the same for many years, the processing equipment as well as design of the mills has continually been improved to increase production while reducing operating and maintenance costs. Also, considerable attention is paid to automatic sensing devices and automatic controls in order to …

compared with gravity separation method and magnetic separation method, froth flotation method must use a certain amount of flotation agents, so its ore processing cost is higher.in addition, the working principle of froth flotation method also determines that it is more complex and stricter than gravity separation method and magnetic separation …
Flotation can be performed by different types of machines, in rectangular or cylindrical mechanically agitated cells or tanks, columns, a Jameson Flotation Cell or deinking flotation machines. The mechanical cells are based in a large mixer and diffuser mechanism that can be found at the bottom of the mixing tank and introduces air, providing a mixing action.
The ore is processed by froth flotation comprising rougher and scavenger cells. The common reagents for copper ore flotation are xanthates as collector, pine oil as frother, sodium cyanide …
In addition, froth flotation is suitable for the separation of fine particles that are difficult to recover by other beneficiation methods. Copper-lead ore has the characteristics of fine particle size and dense symbiosis of useful minerals, therefore, froth flotation is mainly used for the recovery of copper-lead ore at home and abroad.
The copper minerals and waste rock are separated at the mill using froth flotation. The copper ore slurry from the grinding mills is mixed with milk of lime (simply water and ground-up limestone) to give a basic pH, pine oil (yes, it comes from trees -- a by-product of paper mills) to make bubbles, an alcohol to strengthen the bubbles, and a collector chemical called …
17.7 Flotation of Gold-Containing Copper Ores. The floatability of gold from gold-containing copper gold ores depends on the nature and occurrence of gold in these ores, and its association with iron sulphides. Gold in the porphyry copper ore may appear as native gold, electrum, cuproaurid and sulphosalts associated with silver. During the flotation of porphyry copper-gold …
The ore is processed by froth flotation comprising rougher and scavenger cells. The common reagents for copper ore flotation are xanthates as collector, pine oil as frother, sodium cyanide as depressant, and lime to maintain slurry alkalinity. The concentrate in the form of froth and slurry contains +20% copper.
