Operating practices in the beneficiation of major porphyry

Apr 01, 1998· Declining head grades is a major factor in most operations. The relative amount of clay in the ore has increased over the years and the clay composition has changed, especially with the Chuquicamata and El Salvador ores. The presence of clay in the ore reduces the flotation rate of copper in all cases and increases copper losses in the tailings.

Copper Flotation Elmhurst University

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

Major Mines & Projects El Teniente Mine

El Teniente Underground Mine is located 22 km NE from Rancagua, Chile. Chile’s El Teniente deposit is the largest known porphyry Cu-Mo orebody (>70 Mt Cu), and is genetically related to Late Miocene–Early Pliocene igneous activity on the western slopes of the Andean Cordillera (cf. Howell and Molloy, 1960, Camus, 1975, Cuadra, 1986, Skewes and Stern, 1995).

Codelco Wikipedia

The El Salvador mine is a combined open pit and underground copper mine in the company town of El Salvador. The El Salvador mine was purchased by Anaconda Copper, who had little intention of mining it, due to high tax rates by the Chilean government. When the tax rates were reduced Anaconda decided to bring the mine into production.

Lime use and functionality in sulphide mineral flotation

Nov 01, 2019· For treating such a new ore, bulk Cu-Pb flotation followed by Zn flotation has been recommended (Sehlotho et al., 2018). An example of a sequential Cu-Pb-Zn flowsheet is given in Fig. 14 . A first flotation stage is carried out at low pH (pH 6), in which the copper sulphide is floated while both galena and sphalerite are depressed.
