Environmental Impacts

[edit]

The four main types of gold mining include placer mining, hard-rock mining, byproduct mining, and gold ore processing that can all negatively impact the environment by changing the hydrology of streams, destroying land, and polluting soil and water with toxic chemicals such as mercury and cyanide. [1] [2] [3] [4] [5] [6]

Gold reactivity

[edit]

Gold not reacting with KOH/NaOH in solution or molten state can be debated, typical etching with KOH will take time, visible in nano scales.

Page size and split discussion

[edit]

This page has over 12k words of prose, per WP:Article size it should be split. I propose to split the history of gold discoveries into History of gold (this would be in agreement with other element articles like History of aluminium). Additional splits might be necessary.

The article Gallery of gold art and artefacts was created from many images formerly in gold. Not clear if editors will allow this gallery to stand.--Smokefoot (talk) 16:08, 4 December 2025 (UTC)[reply]
While the move might have been necessary for the overall size of the article, moving images does not affect prose size.--ReyHahn (talk) 16:10, 4 December 2025 (UTC)[reply]
Not seeing the need for a split at this time. Jusdafax (talk) 11:30, 13 December 2025 (UTC)[reply]
Please refer to the WP:SIZERULE. We are over 12k words of prose.--ReyHahn (talk) 10:27, 15 December 2025 (UTC)[reply]
