There is a grammatical error in the Folk-medicine section. Change: "In one trial for osteoarthritis and one trial for rheumatoid arthritis, no differences is found between copper bracelet and control (non-copper) bracelet." To: "In one trial for osteoarthritis and one trial for rheumatoid arthritis, no differences were found between copper bracelet and control (non-copper) bracelet."

Additions to History section of article
I essentially only want to edit the history section (copper age & ancient and post-classical) of the copper page and expand upon the relatively little known history of copper usage by very early north American indigenous peoples starting approximately 10,000 years ago. I want to include these additions to the history section of the main copper page because currently the history section is biased towards Eurasia and does not represent historically marginalized peoples from around the world. I understand why this is the case as most of our recorded history comes from this region of the world but as new finding from North America challenge traditional perspectives I feel that the history section should be as up to date and unbiased as possible, reflecting the true historical use of copper globally. Hylaversicolor (talk) 15:18, 1 March 2023 (UTC)
- Sounds very interesting. I am looking forward into reading this new info. DePiep (talk) 04:50, 2 March 2023 (UTC)
sentence needs revision based on the latest findings
The following sentence in quotations needs to be edited because more recent findings may make the following sentence potentially inaccurate. although mining did occur on Isle Royale between 800 and 1600, it does appear to be the earliest evidence of mining copper in the region and more recent publications suggest mining began in the region 8000 years before present. "In North America, copper mining began with marginal workings by Native Americans. Native copper is known to have been extracted from sites on Isle Royale with primitive stone tools between 800 and 1600". Findings from this more recent publication suggest copper mining began in North America 8000 years ago. The sentence in quotations has a reference dated to 1995 and evidence from the more recent scientific study was published in 2013.

Modern history
I'd like to add a sentence to reflect Britain's and the industrial revolution's impact on copper, ... and another for the impact of German miners ... and another to acknowledge the slave trade. However I'm conscious this page was initially about the element Cu, and that there are other pages / articles. Other editors may feel the article warrants a more detailed history for their country or specific interest in mining, smelting milling, coppersmiths etc. Before making changes I thought I'd start a discussion to see if there is any interest.
My proposal:
Add "Germany was a major producer of copper in the 16th century,[1] with mines at Mansfeld and Rammelsberg." before "The Great Copper Mountain ..." and "In the first decade of the 19th century Britain produced over 70% of the World’s copper from Cornish ore smelted in South Wales using Welsh coal.[1] This was helped by the industrial revolution with the use of steam pumps to drain mines.[2] Copper was the “red gold” of Africa and was cast into manilas to trade for slaves, while copper sugar pans were used to refine the sugar cane.[3] As British ore was exhausted New World mines increased in importance with the United States of America becoming dominant for most of the 20th Century and Chile in the 21st century (see List of countries by copper production)" after "Sweden had a copper backed currency."

Richest square mile
I wondered why Kernow/Cornwall and the richest square mile (due to copper) was not mentioned in the Copper article 85.10.117.114 (talk) 14:57, 6 November 2023 (UTC)
- Who makes this claim? And what is the precise nature of the claim? Can you provide a couple of reliable references for it? Feline Hymnic (talk) 15:20, 6 November 2023 (UTC)
- As a relative newbie, I struggle to know how much detail is relevant in an encyclopaedia, especially in a general article like Copper. My feeling is that Kernow's important contribution to the copper industry is best served by a separate article that can provide more context and detail than a general article. There are already articles on Mining in Cornwall and Devon - Wikipedia, Cornish Copper Company - Wikipedia, History of Cornwall - Wikipedia and Cornwall - Wikipedia, which may be appropriate to expand. A link from the See also section of Copper - Wikipedia would be appropriate and hopefully uncontentious... OldCroydonian (talk) 14:04, 7 November 2023 (UTC)

I would like to add an "Environmental Impact" subsection to the "Production" section. Here is what I suggest for the content of that subsection:
The environmental on climate cost of copper mining, as measured in 2019, is estimated at 3.7 kg CO2eq per kg of copper[1]. A more recent report from Codelco, a major producer in Chile, states that in 2020 the company emitted 2.8t CO2eq per ton (2.8 kg CO2eq per kg) of fine copper[2]. Greenhouse gas emissions primarily arise from electricity consumed by the company, especially when sourced from fossil fuels, and from engines required for copper extraction and refinement. Companies that mine land often mismanage waste, rendering the area sterile for life. Additionally, nearby rivers and forests are also negatively impacted. The Philippines is an example of a region where land is overexploited by mining companies[3].
Copper mining waste in Valea Şesei, Romania, has significantly altered nearby water properties. The water in the affected areas is highly acidic, with a pH range of 2.1–4.9, and shows elevated electrical conductivity levels between 280–1561 mS/cm[4]. These changes in water chemistry make the environment inhospitable for fish, essentially rendering the water uninhabitable for aquatic life[5].
Research111 (talk) 20:26, 4 October 2023 (UTC)
- Sounds like a good idea. But there are some spelling mistakes. I could fix those if you don't mind. Adding where emissions come from may be redundant, as effectively every industrial process causes GHG emissions.
- A paragraph on wastes would also be good, and the anti-microbial properties of copper could be pointed out as a contributing factor (if I'm not mistaken). KetchupSalt (talk) 07:53, 10 October 2023 (UTC)
- KetchupSalt: I think you should move forward implementing this, and make adjustments if you think they should be made (after all, you'd do the same if Research111 had directly edited the article themselves).
- I'm marking this as responded-to. Research111: if you think this edit request needs further attention, please feel free to reactivate it by changing the "answered=" parameter to "no".
- --Pinchme123 (talk) 23:12, 12 October 2023 (UTC)
- I added point of KetchupSalt and fixed mistakes. Now seem good to go ? Research111 (talk) 09:18, 16 October 2023 (UTC)
- antimicrobial properties is already listed in Applications/Antimicrobial of the article.
