Utah Mine Tailings Pilot Targets Critical Mineral Supply Hub

Milford Mining Company Utah and Furnace Japan Co., Inc. are advancing a partnership focused on recovering tungsten and other critical minerals from legacy mine tailings in Milford, Utah.

The companies have signed a Memorandum of Understanding to deploy Furnace Japan’s electric resistance furnace technology at MMCU’s operations. The initial pilot will focus on historical tailings, with the option to assess newly mined ore if the process proves viable at scale.

The project comes as mining companies, policymakers and industrial buyers look more closely at secondary mineral sources. Materials once treated mainly as waste are increasingly being reviewed for their potential role in domestic supply chains, particularly as demand grows across electrification, AI infrastructure and defense manufacturing.

MMCU’s Utah assets include copper resources, historical tungsten deposits and legacy tailings that may contain recoverable minerals. For Beaver County, the project could support a broader push to connect local mining activity with critical mineral production and rural economic development.

Utah officials have positioned the partnership as part of a wider effort to use the state’s mineral base more strategically. Rather than relying only on new extraction, the pilot tests whether older mining byproducts can become part of a more resilient supply chain.

Electric Furnace Technology Offers a Lower-Waste Processing Route

Furnace Japan’s electric resistance furnace technology is being evaluated as an alternative to more acid-intensive extraction methods. The process uses primarily electrical energy to treat ore and tailings, which could reduce the need for large-scale acid handling and cut down on related waste challenges.

The technology is also designed to produce stable slag that may be suitable for reuse in industrial applications. That would support a more circular approach to mining, where residual materials are redirected into productive use rather than left as long-term liabilities.

The project’s location may also improve its environmental profile. Milford is connected to a renewable energy corridor with access to geothermal and wind resources, which could support future electric processing operations and reduce the carbon footprint of mineral recovery.

The partnership also reflects wider U.S.-Japan interest in strengthening critical mineral supply chains among allied countries. By pairing Japanese processing technology with U.S. mineral resources and infrastructure, the pilot offers a practical test case for cross-border industrial cooperation.

The next milestone will be whether the pilot plant can recover tungsten and other minerals from tailings efficiently, consistently and with a manageable environmental footprint. If it succeeds, the model could be relevant for other mining regions looking to turn legacy waste into strategic supply.
