Four Industrial Methods for Removing Sulfides to Maximize Metal Recovery

In mineral processing, one of the most critical steps before extracting maximum value from ore is the removal of sulfides. Sulfide minerals can trap valuable metals such as gold, silver, and PGMs, making recovery inefficient if not properly treated. To unlock these values, several industrial methods are used—each with its own advantages depending on ore […]
Rethinking Copper Smelting: Unlocking PGMs Through Matte Metallurgy

In traditional copper processing, sulfide ores are treated as a challenge to eliminate. But what if sulfide isn’t a problem—what if it’s the solution? Modern metallurgical thinking is shifting toward controlled matte metallurgy, where sulfide phases are intentionally used as a collector for high-value metals, including gold, silver, and platinum group metals (PGMs). The process […]
Reimagining Placer Gold Exploration with Autonomous Drone Fleets

Traditional placer gold exploration is slow, labor-intensive, and often limited by terrain. Walking miles with handheld detectors or setting up large survey grids takes time, manpower, and cost. But today, a new approach is emerging—autonomous drone-based gold detection systems designed for continuous, high-efficiency surveying. Imagine a fleet of drones equipped with advanced detection sensors, scanning […]
Achieving 5N Silver Purity Through Electrorefining (ER)

As industries like aerospace, defense, and advanced electronics continue to evolve, the demand for ultra-high purity silver (5N, 99.999%) is rapidly increasing. Meeting this standard requires more than conventional refining—it requires precision electrochemical control. This is where electrorefining (ER) plays a critical role. The process begins with a raw silver bar, which is melted and […]
From Raw Silver to 5N Purity: How Electrowinning Delivers Ultra-High Purity Metals

Producing 5N (99.999%) silver is no longer just a refining step—it’s a critical requirement for aerospace, defense, and advanced electronics. The process starts with something simple: a raw silver bar. But transforming it into ultra-high purity metal requires a precise combination of thermal, chemical, and electrochemical steps. First, the raw silver is melted in a […]
Cyclone Electrorefining: Rethinking Metal Recovery Efficiency

In traditional electrorefining, flat plate anodes and cathodes have dominated the industry for decades. While proven, this approach comes with inherent limitations—slow ion transfer, uneven deposition, and inefficient slime management. Today, a new approach is emerging: Cyclone Electrorefining, a system designed to fundamentally improve how metals are refined and recovered. At the core of cyclone […]
Advancing 5N Silver Production for Aerospace: Avimetal & InyoAG Partnership

A significant advancement in high-purity silver production is underway in Darwin, California, where InyoAG LLC is developing one of the most resource-rich underground operations in the region. Spanning approximately 4,000 hectares with over 200 miles of tunnels, the site contains substantial deposits of tungsten, zinc, and notably silver-rich ore, positioning it as a strategic asset […]
Rebuilding the Missing Link in America’s Mineral Supply Chain

For years, I thought the biggest challenge in mining was finding resources, but the more I studied the industry, the clearer it became that the real bottleneck is not in the ground—it’s in processing and refining. The United States has abundant mineral resources, yet we continue to export raw materials and import finished metals, creating […]
