Copper Smelting Process

2010-4-9 · Introduction to Copper Smelting Techniques. Copper ore typically contains only about 0.6% of the actual copper mineral, the most common ore mined being chalcopyrite. The ore is attained using traditional methods of underground and open pit mining, the later accounting for 90% of the ore used in smelting. The ore …

Copper Ore Processing Methods

2017-4-11 · Copper Ore Processing Methods. The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore ...

Copper Smelting

2.1.1.6.1 FeO–Fe 2 O 3 –SiO 2 Slags. It has been customary since early times in copper smelting, when acid refractories were used universally, to add SiO2 to form a slag with the iron that has been oxidized. This is still the most common practice today, though many furnaces now use basic refractories. Viscosities of slags are important ...

Large scale smelting of speiss and arsenical copper at ...

2012-6-1 · For the grey copper slag, we postulate an origin from the smelting of a ''green'' secondary copper ore to produce arsenical copper. The resulting slag is again consistent with its majority originating from the ceramic and some fuel ash, and a significant amount of additional iron oxide. Here, two scenarios are equally able to explain our data.
