In primary forming, the steel that is cast is then formed into various shapes, often by hot rolling, a process that eliminates cast defects and achieves the required shape and surface quality. Hot rolled products are divided into flat products, long products, seamless tubes, and specialty products.

Mining and Refining – Process - World Aluminium

The ore grade, or concentration of an ore mineral or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore is of too low a grade to be worth mining.

Ore - Wikipedia

Lead for recycling may be in the form of scrap metal (roofing sheet, for example), or compounds of lead, such as the pastes from lead-acid batteries. Clean metallic lead can be melted and refined directly, but compounds and lead alloys require smelting, using processes similar to those used with lead ores.

what is the metal ore process - prahavpohybu.eu

2018-11-24· Smelting is a process for extracting usable ore from mixed deposits where people find ore bound with other metals, rock, and extraneous material. It is very unusual to find deposits of pure ore and this method allows people to separate out useful metals. The invention of this process was an important step in the development of human societies, allowing people to make more complex metal ...

Extracting a metal from its ore - chymist.com

Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as "beneficiation", which include washing, wet screening and mechanical or manual sorting. Beneficiating ore also reduces the amount of material that needs to ...
