Pyrometallurgical Copper Making. The main raw material is copper sulfide ore, and high-grade copper oxide ore can also be smelted in the pyrometallurgical process. The mining grade of copper sulfide is 0.3–2%, and the average mining grade is approximately 0.81%. The mined ore is crushed and pulverized.Web

Copper processing - Roasting, Smelting, Converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace of either …Web

Follow these steps to prepare the inside of the copper pipe: Use a deburring tool to ream or deburr the inside of each pipe. Run the tool around the inside of the pipe. This removes the burrs. Make sure the copper shavings don't go into the pipe or pipe fitting. Tap the pipe to get any shavings to fall out.Web

Copper is a metal with a reddish-brown color and is widely used due to its high thermal and electrical conductivity. Learn more about it here. ... According to the two common types of copper ore, there are …Web

Primary copper of the best grade is used for producing the rod for this work. Uncontaminated recycled process scrap and other scrap that has been electrolytically refined back to grade 'A' quality may also be used. The copper used for power cables is also drawn from high conductivity rod but to a thicker size than fine wires.Web

Keep an eye on the copper so you can gauge its temperature. Once the metal returns to its original reddish-brown color, use the pliers to remove the copper from the metal bucket. The cooling process should take less than 5 minutes. Once this time has passed, the copper is now annealed and will be soft and malleable for working.Web
