The impacts of the copper production processes are strongly conditioned by the copper content of the ore (ore grade) (Northey et al., 2014). Therefore, it is relevant to consider the reduction in the average copper ore grade in Chile when assessing the GWP and assessing future mining operations.

After a brief review of these associations, we describe the ubiquitous occurrence of remnant petroleum in two representative "manto-type" stratabound copper deposits in Chile and suggest its ...

Copper-containing rock, or copper ore, holds only a small percentage of copper. Most of the rock is unwanted material, typically referred to as gangue.There are two main types of copper ore that ...

Chilean copper oxide ores that are processed by hydrometallurgy are becoming increasingly scarce (estimates suggest a potential decrease from 30.8% in 2015 to 12% by 2027); conversely, the proportion of copper sulphide ore is continually growing as deposits are mined to increasingly greater depth [2].Sernageomin pointed out that 39.2% of refined copper is …

The Cobriza Cu-bearing skarn is the only significant copper deposit of pre-Mesozoic age. Perú has many ore deposits associated with the Miocene felsic extrusive and intrusive rocks along the Cordillera, forming veins and disseminations in igneous rocks and noncarbonate sedimentary rocks, and replacement mantos, pipes and veins in limestones.

Each metallogenic epoch introduced its own deposit type(s), of which porphyry copper (and related skarn), followed by sediment-hosted stratiform copper and then iron oxide copper-gold (IOCG), are globally preeminent. Nonetheless, genesis of the copper provinces remains somewhat enigmatic and a topic of ongoing debate.

The ores of sulfide copper-nickel, copper-pyrite deposits, and ores of copper sandstones and slates are primarily pro-cessed abroad. The amount of copper in copper sand-stones and slates varies from 1 to 6%, in sulfide cop-per-nickel ores from 1.1 to 4.9%, in copper-pyrite ores from 0.1 to 3%, and in copper-porphyry ores from 0.4 to 1.2%.
