The Olympic Dam is a huge mining centre located in South Australia, 560km northwest of Adelaide. Home to a major oxide copper gold deposit producing copper, uranium, gold and silver, the site hosts an underground mine and an integrated metallurgical processing plant. The project was opened in 1988 by WMC Resources, after discovering the large ...

The smaller ore will go on to the ball grinding mills where they will be further ground down. The larger ore will be routed to a pebble crusher to reduce the size to cm (½ in) and will return to the SAG mill stage. The ball mill product is pumped to cyclones which separate out the coarse material with the fine ore.

Iron and Steel Production. Iron production requires iron ore, coal and stone ( limestone, dolomite). Steel production requires iron, steel scrap and flux ("lime" — calcined limestone). The iron ore is smelted to produce an impure metal called "hot metal" when liquid, or "pig iron" when solid. The hot metal is refined to remove impurities and ...

Pig iron is produced principally by the reduction of iron ore in a blast furnace, using coke or charcoal as reductant. In integrated steel mills, liquid iron (hot metal) is transferred directly to the steel plant for refining into steel. For the merchant market, liquid iron is cast into ingots which when cooled can be delivered to customers.

Discovering metalrich deposits commonly requires extensive searching, and exploration is the first step in the mining cycle. Once exploration geologists find an area with metals, they determine whether it is of sufficient size and richness to be mined profitably. If the deposit is rich enough, activities to extract the metals from the Earth begin.

A conventional uranium mill is a chemical plant that extracts uranium using the following process: Trucks deliver uranium ore to the mill, where it is crushed into smaller particles before being extracted (or leached). In most cases, sulfuric acid is the leaching agent, but alkaline solutions can also be used to leach the uranium from the ore.
