COPPER Copper production TU Delft

Copper production About 80 % of primary copper production comes from low grade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below) 1. Beneficiation by froth flotation of ore to give copper concentrate

Iron Extraction Process Dillinger

Iron Extraction Process. Exact quantities of burdening materials such as sinter, pellets, lump ore, alloys, and coke are transported alternately via a belt conveyor to the blast furnace head. The materials are then charged in layers via sluice vessels into the furnace by means of a rotary chute.

Processing, smelting and refining gold World Gold Council

The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis.

Charging the blast furnace. 1 After processing, the ore is blended with other ore and goes to the blast furnace. A blast furnace is a tower shaped structure, made of steel, and lined with refractory, or heat resistant bricks. The mixture of raw material, or charge, enters at the top of the blast furnace.

Steelmaking

The HIsarna ironmaking process is a process in which iron ore is processed almost directly into liquid iron or hot metal. The process is based around a type of blast furnace called a cyclone converter furnace , which makes it possible to skip the process of manufacturing pig iron pellets that is necessary for the basic oxygen steelmaking process.
