Aluminum processing - Ores, Refining, Alloying: Aluminum is the third most abundant element on Earth's surface. Only oxygen and silicon are more common. Earth's crust to a depth of 16 km (10 miles) contains 8 percent aluminum. Aluminum has a strong tendency to combine with other common elements and so rarely occurs in nature in the metallic form.

Iron smelting is the specific smelting process used to extract iron from iron ore. This process involves reducing iron oxide to produce molten iron, which is then cast into various forms like bars or ingots. What is the Process of melting metal called? The process of turning solid metal into its liquid form is called melting.

Conventional milling is one of the two primary recovery methods that are currently used to extract uranium from mined ore. 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).

Alternatively, uranium may be recovered from the ore using a heap leach process. In the heap leach process, the ore is placed on a engineered barrier and sprayed with acid. The uranium dissolves into solution and is collected at the engineered barrier. The solution undergoes additional chemical processing to produce "yellowcake".
