Chalcopyrite is the most common ore mineral for copper and is a sulphide of iron Pyrite and gold can be quite easily distinguished from one another: pyrite is
At Nordgruvene during the second half of the 1800s pyrites was the main type of ore extracted, but at Storwartz copper pyrite was always the main product.
The highly pyritic copper and gold bearing ores of the district were the subject of intensive experiments in smelting, culminating in the first successful operation in
The exploitation of copper sulfide minerals led simultaneously to the recovery of other sulfide minerals, mainly the iron pyrite. The metallurgical methods which
