Fig. 2 shows a flow sheet of the industrial aluminum production process [32]. Generally, the processes conducted before the metal is sent to the casting house are called the upstream processes, while the processes in the cast house for making extrusion ingots, sheet ingots, primary foundry alloys, and wire rods are called the downstream processes.Web

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and …Web

Process done in a basic lined vessel and Lime added as slag former to combine SiO2. Oxidizing and enough volume of slag is formed to promote phosphorous removal. Process generates a lot of heat of oxidation which is compensated by iron ore/scrap additions as a coolant. Next Class task: • Material and heat balance of processes.Web

After establishing the detailed individual flow sheet segments for the various extraction, concentration, and recovery process streams, the overall flow sheet must be developed. The overall flow sheet is easy to develop once the individual segments are completed, since the overall sheet consists of connecting the individual segments.Web

solvent-extraction or ion-exchange. The uranium industry was the first hydrometallurgical industry to make extensive use of these two unit operations. The active agent in the solvent-extraction process is usually an organic amine salt, diluted in kerosene, that can selectively extract the uranium ions into an organic complex which is insoluble ...Web

Mild steel. Mild steel is iron containing up to about 0.25% of carbon. The presence of the carbon makes the steel stronger and harder than pure iron. The higher the percentage of carbon, the harder the steel becomes. Mild steel is used for lots of things - nails, wire, car bodies, ship building, girders and bridges amongst others.Web
