Extraction and refining. The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper.

How is sulfur extracted from its ores? - Quora

There are no (or very little) sulfur ores, at least today. The main source is the purification process of natural gas and oil : the sulfur is converted into H2S and part of it is burned into SO2 which then react with H2S : SO2 + 2 H2S → 3 S + 2 H2.
