Metal Profile: Iron Properties and Characteristics

Jan 12, 2020 · Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores. The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BCE.

How Is Magnesium Metal Produced?

Nov 24, 2019 · Electrochemical processes are used to extract the metal from dolomite and magnesite ore. When dolomite is crushed, roasted and mixed with seawater in large tanks, magnesium hydroxide settles to the bottom. Heating, mixing in coke, and reacting with chlorine, then produces molten magnesium chloride.

Gold Smelting Process | Sciencing

The first step in the gold smelting process occurs when ore containing gold is mined from the earth. At this point, the crude binding matter and the gold metal need to be separated. This is accomplished by pulverizing or crushing the gold ore, and then placing it in a furnace.

Lead - Essential Chemical Industry

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.

Mining and Refining – Process

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.

Weathering process can also provide metals to ores which are produced by other processes. Disseminated deposits contain metals but are not economical to mine so ground water and rainfall weathers these metals. In some cases metals react to weathering instead of removal which creates a supergene ore rich in metals above low grade mineralization.
