A geochemical characterization of copper ore

2021-6-21 This study presents a new isotope and element-composition database of copper ores from Mallorca and Menorca. The main goal of this paper is to characterize copper resources from the Balearic Islands and demonstrate how this database can contribute to furthering studies on the origins of archaeological materials from the Western Mediterranean.

ROCK MASS CHARACTERIZATION OF PRIMARY COPPER

In order to characterize the rock structure of the primary copper ore, line sampling techniques were undertaken in mine drives within two levels of the Teniente Sub-6 Mine sector (Figure 3). Two structural domains referred to as andesite Hw (hangingwall) and Fw (footwall) were characterized

Rock Mass Characterization Of Primary Copper Ore

2021-4-4 Rock masses of the primary copper ore at the El Teniente Mine are very competent and massive. The rock mass contains almost no open discontinuities. Nevertheless, there is a high frequency network of small discontinuities coupled with widely spaced faults. A data collection campaign designed to characterize the rock structure was recently implemented.

Copper Ore an overview ScienceDirect Topics

Copper ore usually contains about 0.5 to 2% copper that occurs in the form of disseminated and stringers. The run of mine ore is reduced from 150 mm to 25 mm size in Jaw and Cone crushers. The crushed ore is grinded in ball mills to −74 μm size. The ore is processed by froth flotation comprising rougher and scavenger cells.

ROCK MASS CHARACTERIZATION OF PRIMARY COPPER

Open joints are rarely found within the primary copper ore, and faults have a very low frequency of occurrence in line sampling (0.1 m–1) [Brzovic 2001]. Joints and faults are the only open discontinuities at the El Teniente Mine. Thus, the primary copper ore rock mass prior to caving can be described as very competent, massive, and imperme-able.
