Good luck! Mjsv23 (talk) 16:52, 22 March 2019 (UTC)
 * I like that you are specific about what you want to add to the article, especially since the topic is very broad.
 * It’s interesting to me that you chose “tonnes” over “tons”, since your source used “tons”, but it doesn’t really matter since you aren’t using numbers. If you could find an average deposit size, however, that would certainly add.
 * It’s unclear what you mean by “one of the first sources of iron ore is bog iron.” Do you mean it was one of the earliest sources utilized by humans?
 * Overall I like what you’ve done and I think you will greatly improve the article.

Raw Materials

 * I chose this article because the topic is so open ended and there is very little in the way of actual information. The article is missing a lot since it only covers the bare minimum of information. We want to add a specific section on iron ore.

Editing article
Metallic raw material production follows the processes such as crushing, roasting, magnetic separation, flotation, and leaching (at the first step), smelting and alloying (at the second step).

Passages from sources:

The first two, in principle, can be estimated directly from geophysical data (heat flow, density), with some iteration via thermal and seismic models. Fe can thus be determined to better than +10% in all three planets, but U is known to only about +30% in the Earth (28,29) and not at all for Venus and Mercury; the(Earth-like and Moon-like) values in Table1 are educated guesses, based on the apparent trend of U content with size(8) and a few scraps of evidence suggesting Earth-like and Moon-like composition for these two planets.

On the sunward side of the Earth, two data points are available. A spectrophotometric measurement for Mercury (37) suggests that pyroxenes on its surface have about the same FeO content as do those in lunar highland soils-i.e.,5.5%.This FeO must come from local rock, not from a meteoritic component, because the later typically comprises less than 4% of a regolith and contains < 30% FeO (38). For Venus, the latest thermo- dynamic calculations, assuming equilibrium between surface rocks and the atmosphere(39),suggest an FeO activity of 10-3-10-2-i.e.,1-2 orders of magnitude below the value for the Earth. But this result applies only to the surface rocks, whose chemistry is controlled by the massive, hot atmosphere. It does not preclude a higher FeO content in the bulk planet. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC350422/pdf/pnas00499-0036.pdfCcb8r8 (talk) 20:24, 17 March 2019 (UTC)

Historians claim that the Iron Age began between 1500 and 1000 B.C. (at least in some parts of the world). This does not mean that iron was unknown to man before that time; quite the contrary is the case. Meteoric iron (which has a large nickel content) must have been used by prehistoric people as early as 4000 B.C. They made tools and weapons from it by shaping and hammering. It is thus quite understandable that in some ancient languages the word for iron meant "metal from the sky". Naturally, the supply of meteoric iron was limited. thus, stone, copper, and bronze were the materials of of choice at least until the second millennium B.C. There were, however, some important uses for iron ores during the Bronze Age and also during the Chalcolithic period. As explained already in Chapter 1, copper needs a fluxing agent for the smelting process when using malachite. For this, iron oxide was utilized, which was known to react during smelting with the unwanted sand particles that are part of malachite. Eventually, a slag was formed which could be easily separated form the copper after the melt had cooled down. https://books.google.com/books?id=DaAmwiJ4rnEC&pg=PA125#v=onepage&q&f=false Ccb8r8 (talk) 20:24, 17 March 2019 (UTC)

Changes:

Many raw metallic materials used in industrial purposes must first be processed into a usable state. Metallic ores are first processed through a combination of crushing, roasting, magnetic separation, flotation, and leaching to make them suitable for use in a foundry. Foundries then smelt the ore into usable metal that may be alloyed with other materials to improve certain properties.

Material in the process of being added/already added:

One metallic raw material that is commonly found across the world is iron, and when combined with nickel, this material makes up over 35% of the material in the Earth's inner and outer core. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC350422/pdf/pnas00499-0036.pdfCcb8r8 (talk) 20:24, 17 March 2019 (UTC)

The iron that was initially used as early as 4000 B.C. was called meteoric iron and was found on the surface of the earth, as this type of iron came from the meteorites that struck the earth before the humans appeared and was in very limited supply. This type of iron is unlike most of the iron in the earth, as the iron in the earth was much deeper than the humans of that time period were able to excavate. Due to the nickel content of the meteoric iron, it did not need to be heated up and instead, was hammered and shaped in to tools and weapons.[1]https://books.google.com/books?id=DaAmwiJ4rnEC&pg=PA125#v=onepage&q&f=false Ccb8r8 (talk) 20:24, 17 March 2019 (UTC)

Iron Ore
Iron ore can be found in a multitude of forms and sources. The primary forms of iron ore today are Hematite and Magnetite. While iron ore can be found though out the world, only the deposits in the order of millions of tonnes are processed for industrial purposes. The top five exporters of Iron ore are Australia, Brazil, South Africa, Canada, and Ukraine. One of the first sources of iron ore is Bog Iron. Bog iron takes the form of pea sized nodules that are created under peat bogs at the base of mountains.

 * 1) overall you have very good information on ore deposits of iron which is a major raw resource.
 * 2) changes as a note in the other sandbox they stated that we are currently not recycling resources. This is a false statement. I suggest you do reasearch on recycling methods for in particular steel and aluminum. Both of these have substantial fields and for steel over 60% of the steel produced in the US in 2016 is produced via recycling methods and it has only increased in recent years.
 * 3) What is the most important thing to improve.I am focusing majorly on the technical side of these additions. I would say adding more information on other ores would be good (make sure to spell out the name and do not do the simple chemical nomenclature). as well as if you have time going into briefly current recycling methods and discussing the current prevalent ways to process many ores and such.
 * 4) As an additional note. I did not have time to look at your sources so this is not a comment based on your current sources, however, sources for the field of ore processing tend to be very very old. (published in 1950's etc) but they are still very current. The field has not changed in many ways for a long time but at the same time new processes come out all the time, make sure to double check sources for these things especially for aspects such as recycling.
 * 5) Overall this is a great start to your edits, this is obviously a very important part of our ecosystem that needs to be noted and it is a very large topic to cover. I look forward to seeing what you guys do with it! FredHGroth (talk) 16:41, 22 March 2019 (UTC)

Alan Zimmer (talk) 16:34, 17 March 2019 (UTC) The sections wrote out flow nicely together, making for an easy read. The sections where kept short, sweet, and to the point. Something I would recommend would be to change the order of your sections so that the history comes after the description. As it stands, the readers are being told how it was important to history with only the introduction of what it is. Other than that, your article is well under way.

Q: What does the draft do well? Is there anything from your review that impressed you? A: The draft does a good job explaining the description, type, and location of Iron Ore. Nothing is over the top, good neutral tone.

Q: What changes would you suggest the author apply to the article? Why would those changes be an improvement? A: Taking a quick peek at the current article on "Raw Materials", it seems the draft on iron ore seems too much in depth? I would suggest adding in information about the history, importance, and impact of raw materials rather than going in depth with one specific type of raw material. For example, you can talk about an example of what iron ore is used for in-depth and relate it back to what makes it a raw material. I say these changes are an improvement because iron ore can be explained

Q: What's the most important thing the author could do to improve the article? A: Citation types. When I go to these sites, they do not reference back to a scholarly article or book. Try to find sources that are easily credible and referenced really easily, instead of using web.archive.org. [.org may be considered to be a basis of persuasion, be careful]

Q: Did you notice anything about the article you reviewed that could be applicable to your own article? A: Using lots of "See Also" external links to other related articles and having good pictures for the article.
