Copper Ore - an overview ScienceDirect Topics

The principal copper ore mineral is chalcopyrite (CuFeS2 ), which is commonly smelted to yield a matte containing ∼50% copper. In the presence of silica flux, iron is selectively oxidized to a slag. Figure 14 shows a PSD for the Cu–Fe–S–O system at 1 atm SO 2 as a function of temperature (

Copper Ore - an overview ScienceDirect Topics

Cadmium occurs naturally in the environment at low levels, usually with zinc, lead and copper ore deposits. It is one of the most toxic industrial and environmental heavy metals because of its long half-life and multifaceted deleterious effects (Domingo, 1994).High cadmium concentrations are often associated with industrial emission sources like mining and smelting operations.

How much metal does the ore contain? « World Ocean

The metal recovered is described as “refined copper”. Mineral ores, therefore, are made up of a combination of different substances and contain only a certain amount of metal. In most cases copper ores contain between 0.6 and 1 per cent of copper. Consequently one tonne of ore generates a maximum 6 to 10 kilograms of copper.
