MINING

Copper - FLSmidth

This mechano-chemical process can leach 97-99% copper directly on site from concentrates as low as 5% copper in less than six hours. This makes it feasible for you to produce cathode copper from concentrate directly at the site rather than to sell the concentrate to a smelter. The ROL process can even leach copper from arsenic-ladden concentrates.

Flotation Solutions - Maximizing Mineral Recovery | Ecolab

A copper mine in South America partnered with Nalco Water to help achieve their operational goals. The goals included improving recovery through their copper flotation circuit increasing productivity and ultimately reducing the total cost of operations while ensuring a safe production environment.

The recovery of these copper minerals by flotation or hydrometallurgy from ores typically containing 0.5%TCu (open pit mines) and 1-2%TCu (underground mines) is of great commercial importance.

Copper Flotation - Mineral Processing & Metallurgy

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 3000 ton per day operation.

60 Centuries of Copper: The Flotation Process

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.
