The reason appears to be price related, with lead salts being cheaper, as copper sulfate has been shown to be the superior activator for many stibnite ores. ... Jones et al., 1986) has been successfully applied at a number of copper–gold ore flotation plants in Australia (Engelhardt, 1990, , 1990).
Only the flotation process mentioned above could make this practicable; and even so, it requires large companies with huge plants, continuous working and immense capital. 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.

Copper Ore Processing Plant in India: Froth Flotation The copper grade of a copper concentrator in India is 3.27%. The particle size is fine. FTM Machinery has configured a production line for customer based on the characteristics of copper mines. copper mine: froth flotation method Ore processing flow:
Flotation Plant. The actual process of concentrating the minerals by flotation is but one of a sequence of operations, a complete flotation plant comprising five of these: ... 20% pine-oil. In the Coeur d'Alene on zinc ore we used straight wood- creosote; on the National Copper ore plain turpentine will work, but pine-oil is better. At the ...
A new method, staged flotation for effectively increasing the recovery of ultra-fine copper oxide ore with a new type of collector (ZH-1, C3-5 carbon chain xanthate) is proposed for the first time. The flotation process and mechanism were examined by flotation tests, entrainment rate analysis, laser particle size experiments and …
Figure 1 is a generalized diagram of a conventional copper flotation plant from the point where ore first enters the circuit to the production of concentrate and tailings. To prepare ore for the flotation process, run-of-mine ore, which may contain from about 2 to 5 percent water, by weight, when mined, is
