Evaluate the drafted changes
Under the Extraction of copper heading the lead has been updated describing the two main methods that will be discussed under subheadings. I think that this adds significant value to the article as it offers a brief description of each extraction method as well as stating which of the two is the most commercially viable which is important to the reader as it indicates industry methods and paints a fuller picture. This lead is also important as it is a brand new section being added to the article which clearly and concisely states what the following portion of the article will talk about as well as state new information that is not found else where in the article. an example of this clear new information is in the lead it states that pressure oxidation leaching is practiced which is a clear description and addition to the article. Another example of high clarity information in the lead is through the description of the steps in each of the two methods described where just the information is stated in a sequence of events. Overall the entire lead is concise, logical and introduces the new topics being discussed in a clear and objective way without any bias as it is stating clear cited facts. The citations are especially good in this lead as not only is each fact cited but in addition there is a section at the bottom under personal notes which describes what each citation discusses which in my opinion will really help in refining the article for the finished version later and is a particular strong suit of this draft.

As for the content within the actual article there are clear headings and an outline of information to be added later. one such example is that under production there is a clearly stated fact along with a citation and plans following where media will be added to enrich the article. these two plans are a map of chalcopyrite mines and a diagram of resources and reserves which I think would enrich the article as images are a concise and quick way to convey information on a topic, benefiting the article greatly. In addition there is also a clear structure being implemented and a high degree of organization and logical flow within the planned additions of the article as well as what has actually been added. For example the planned additions start out with the uses which is important to discuss as it is the reasons why we are using chalcopyrite in the first place. Then the next planned section talks about mining and production which links back to uses as it describes how we get from rock into the ground to those uses as well as planning on discussing hazards associated with the production. Then the article logically flows into the extraction of copper, further building upon the overall picture of this ore by describing the next step in the process of mining and extracting until we can reach the usable states that will be added in the uses portion. These planned additions also show balanced coverage as the article plans to cover not just the uses of copper and chalcopyrite but also hazards associated with mining, various methods of extracting the copper, and mining and production on a global scale of this copper. leading to very balanced coverage and a good picture of chalcopyrite as a whole.

As for what has been added the main additions fall under the hydrometallurgical processes sub heading. Within this heading there is a clear flow without any spelling mistakes or grammatical errors. In addition the content within this subheading is up to date as there are journals being cited which are as recent as 2022. In addition this heading describes how chalcopyrite is different to other copper minerals and compares and contrasts them through the description of how other copper minerals can be leached in atmospheric conditions but chalcopyrite cant be leached the same way and describes how chalcopyrite has to be leached. In addition there are working wiki links to other Wikipedia pages which is a strong point of this article. In addition There is also a detailed chemicals formulas describing the reactions of pressure oxidation leaching which i think adds to the article and belongs in the article as it breaks down all the steps in this reaction series.

The article as a whole maintains very neutral language and doesn't take a position on any of the facts stated. one such example of the neutral language and view point is when discussing the advantage of hydrometallurgical processes over pyrometallurgical processes. In this discussion facts are simply stated such as that one process is able to treat high impurity concentrates better than another but doesn't say that through this one should be used over another. Another example of this neutrality is that after listing various examples of one process the article states that this method also faces challenges and in fact that the other method of extraction is the most commercially viable. Through this it can be seen that there are is no particular bias towards one method of extraction over another and there is no language to indicate that one method is better than another, showing that there has been no attempt to sway the reader in any way. As it stands right now however there is a bias towards one extraction because only one method has been discussed within the additions made however there is plans to discuss the other method so this bias is only temporary and already has plans for remedying it.

As for sources and citations this article doesn't make a statement without citing it in an accurate, up to date, peer reviewed source. One such example is through the second sentence in the lead that describes the most common and commercially viable method of pyrometallurgy. The commercially viable statement is cited through a peer reviewed industry journal and the second half of the sentence is cited through a second article describing the techniques used for chalcopyrite ore processing. In addition to the rigorous citation, all links work and are from modern up to date sources which are thorough and reflect the literature well in addition to being peer reviewed and published. These sources add much as they are from different universities, journals and part of the world and as such they represent a diverse view point on the various subjects discussed within and add much to the article. Since every fact stated within the article is cited through a journal or reputable source I cannot suggest a citation for what has been written. In addition within the planned and personal notes section there is also citations listed for information that has not been added yet such as citations for the pyrometallurgical extraction and as such i cannot suggest citations for those unfilled fields either. As such i can only suggest articles or citations that might be helpful such as this http://doi.org/10.3390/books978-3-0365-2080-3 book which describes hydrometallurgical processes of various ores including chalcopyrite and also links to other papers which could be of some use.

Overall this article has many strengths such as its organization displayed through the section planning heading. Its citations are also a particular strong suit as everything is cited or has plans to be cited such as in the pyrometallurgic section. Another strong suit of the article is its objectivity where both methods of extraction are planned to be talked about and there is only facts stated and no personal view points. Another strength of the article is through the clarity of grammar, the lack of spelling mistakes, and the article's concise nature and writing. One suggestion i can make that i feel would add greatly to the article would be a within the mining section to add an associated minerals section which describes what ore minerals can form in the same environments as chalcopyrite. I feel that this section would be good to include as it would describe ores that could act as "sweeteners" or extra incentives to mine chalcopyrite which would add to the overall image of mining chalcopyrite within the article.
