Effect of Copper and Iron Ions on the Sulphidizing …

Abstract The treatment of smelting slag has attracted much attention nowadays. This study investigates the influence of Na 2 S, CuSO 4, and FeCl 3 on sulphidizing flotation of copper oxide. The results show that a proper Cu 2+ concentration can increase the sulphidizing effect of copper oxide, while Fe 3+ inhibits the sulphidizing effect. ...

Copper vs. Cuprous Oxide: What is the Difference?

Copper vs. Cuprous Oxide: What is the Difference?

Right underneath the free agent electron level is a level jam-packed with electrons - no more can fit on this level. This means that transferring electrons from this level is very difficult. As a result, copper''s metallic bonds only exist on this outer layer of free-moving electrons, a pretty weak bond as …

Diodes part 1: Homemade copper diodes

On the weekend I played around trying to make copper-oxide diodes. I succeeded in making something diode-like, but it behaved more like two opposite-facing diodes in parallel. In the rest of this post I''ll detail how I made my ''un-odes'' and their test results in the hope of encouraging other people to tinker with home-made semiconductors.

Copper does not react with water, but it does slowly react with atmospheric oxygen to form a layer of brown-black copper oxide which, unlike the rust that forms on iron in moist air, protects the underlying metal from further corrosion (passivation).A green layer of verdigris (copper carbonate) can often be seen on old copper structures, such as the roofing of many older buildings and the ...
