Copper Mining and Extraction Sulfide Ores
One way of solving the problem is to convert it to sulfuric acid. This is either sold for industrial use or used to extract oxide ores of copper by leaching. Stage 4: Smelting with fluxes The calcine is heated to over 1200 °C with fluxes such as silica and limestone. The calcine melts and reacts with the fluxes.

Smelting - Wikipedia
Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

What Is Activated Charcoal and How Does it Work?
Activated charcoal is carbon that has been treated with oxygen.The treatment results in highly porous charcoal. These tiny holes give the charcoal a surface area of 300-2,000 m 2 /g, allowing liquids or gases to pass through the charcoal and interact with the exposed carbon. The carbon adsorbs a wide range of impurities and contaminants, including chlorine, odors, and pigments.

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
