flash converting anode impurities

Kumera PeirceSmith Converter. In converting, the impurities are removed from copper matte. The most important are iron, sulphur, lead, zinc, arsenic, antimony, tin and bismuth. At the converting stage gold, silver, nickel and selenium remain in the copper. Sulphur is oxidized by oxygen enriched air to sulphur dioxide and is then normally...

Anode effect. Anode effect is a situation where too many gas bubbles form to the bottom of the anode and join together forming a layer. This increases the resistance of the cell when smaller areas of the electrolyte touch the anode.

The sulfur dioxide concentration in the off gases from flash furnaces is also higher, over 30%, and less expensive to convert to sulfuric acid (note: the INCO process results in 80% sulfur dioxide in the off gas). Flash processes have been in use since the 1950s.

In midSeptember, the failure of a taphole coolingblock resulted in extensive damage to the converting furnace. They were replaced with one flash smelting furnace, one flash converting furnace, and two anode casting furnaces while doubling production.

The basic oxygen furnace (BOF) is a vessel used to convert pig iron, of about 94 percent iron and 6 percent combined impurities such as carbon, manganese, and silicon, into steel with as little as 1 percent combined impurities. The BOF is a large pearshaped unit that can be tilted to charge and pour.

Cathode: O2 + 4e– → 2O2 (1) Anode: C + 2O2 → CO2+ 4e– (2) The fuel is housed on the anode side of the membrane with air being used as the oxidant on the cathode side. The oxygen molecules become ionized [reaction (1)], and the oxygen ions flow across the membrane and react with the fuel to produce CO2 [reaction (2)].

6. Corrosion of pipeline TYPES OF CORROSION Basically, there are four ways corrosion can occur. Corrosion can occur through a chemical reaction or three general types of electrochemical reactions. The three general types of electrochemical reactions that occur depend on the cause of the potential difference between the anode and the cathode.
