These United Kingdom-based mining companies are primarily large, established firms, with several founded in the 19th century. They specialize in a wide range of essential materials. For example, Rio Tinto provides iron ore, copper, and aluminum, while Anglo American focuses on various metals and minerals with an emphasis on sustainability. The Weir Group PLC offers mining technology solutions, and Endeavour Mining is a senior gold producer operating in West Africa.
A significant concentration of these companies, including Rio Tinto, Anglo American, Endeavour Mining, and Vale Base Metals, have their headquarters in London. This suggests a strong hub for mining operations and related services within the capital.

Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
