Blister Copper an overview ScienceDirect Topics

Blister copper. The unrefined copper of about 98.5% purity produced from the converting step of copper smelting. Calcium ferrite slag. A slag based on CaO that contains FeO and Fe 2 O 3, which can absorb highly oxidized iron and thus is used in continuous copper converting under higher oxygen partial pressures than in conventional converting processes.

The Process of Metal Extraction from Ore Term Paper

The Process of Metal Extraction from Ore Metals are produced when metal oxides have their oxygen removed. The process of metal extraction from ore is dependent on the reactivity of the metal. Highly reactive metals are extracted by electrolysis. In order of decreasing reactivity, these metals are potassium, sodium, calcium, magnesium and aluminum.
