flotation of copper ore in el salvador

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

Flotation of Copper Ores Mineral Processing & Metallurgy

Feb 11, 2016· Pneumatic flotation is already fully established in a number of places and the results in comparison with the other and older schemes fully justify the opinion of your correspondent that it constitutes the most distinct advance in flotation in recent years. The first pneumatic-flotation plant in this country was erected by me in February 1914 for the National Copper Company at Mullan, Idaho,

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.

Major Mines & Projects Mirador Mine

Run-of-mine ore will be crushed in a gyratory crusher. The mill flow sheet selected for Mirador will be a conventional copper-gold porphyry flowsheet, with relatively coarse primary semiautogenous and ball mill grinding to about 150 µm followed by copper rougher flotation, concentrate regrind to 30 µm, and cleaner flotation and dewatering.

Chapter 12: Flotation of Copper Sulfide Ores Engineering360

From a processing point of view, copper ores could be divided into: Copper sulfide ores, where the pyrite content can vary from 10% to 90%. The predominant sulfide mineral in this ore is pyrite, but may also contain pyrrhotite and mar-casite. Some copper sulfide ores also contain significant quantities of

Copper price to rise in 2021: analysts S&P Global Platts

Copper's long-term demand is backstopped by green energy and the push toward it, "as it is significantly more copper intensive than traditional, fossil fuel-based infrastructure," Stifel said. "We are updating our LT [long-term] Cu price to $3.40/lb ($7,496/mt). We believe a combination of short- and long-term market support in pricing."

Molybdenite Flotation Metallurgist & Mineral Processing

Molybdenite, M0S2, occurs in porphyry copper deposits in concentrations varying between 0.020% -0.035%. By-product molybdenite technology includes two stages: A Cu-Mo sulfides bulk flotation; and A molybdenite selective flotation. It is well known that molybdenite is a mineral with natural floatability (intrinsic hydrophobicity), and under conventional flotation technology is recovered

12.5: FLOTATION PRACTICE IN BENEFICIATION OF SULFIDE

Primary copper-gold ores may contain between 6% and 50% pyrite and primarily contain chalcopyrite. In some cases, bornite and covellite may be present in the lower portion of the ore body (Batu Hijau, Indonesia) or enargite (El Indio, Chile). In other sulfides, these ores contain pyrite and sometimes arsenopyrite and pyrrhotite.
