Innovations: Introduction to Copper: Mining Extraction
The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfurbearing volcanic magmas, which have separated into metal sulfides and siliceous melts.

This page looks at the extraction of copper from its ores, its purification by electrolysis, and some of its uses. Before you get too bogged down in the extraction of copper, make sure that you need it for whatever syllabus you are using. Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of
Copper Leaching Method. View Larger Image Table of Contents It has been found in leaching an ore carrying large amounts of lime and iron that when the lixiviant becomes weak in acid, basic iron salts and gypsum separate and clog the interstices between the ore grains, causing the flow to cease. Extraction of copper from suitable ore by
