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 […]
Advancing Mineral Separation: A Hybrid Electrostatic System Based on Triboelectric Theory
As ore grades decline and fine particle recovery becomes more critical, conventional separation methods are reaching their limits. Electrostatic separation, particularly based on triboelectric (tribotic) charging, is gaining renewed attention—but even this technology has room for improvement. That’s where a hybrid roller and plate-type electrostatic separator comes in. Traditional electrostatic systems typically rely on either […]
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 […]
How to Unload Avimetal’s Container-Framed Modular System from a 40ft High Cube Shipping Container

The module is built with a strong gray container-style frame designed for fast and safe unloading at your site. Here are three proven methods:1. Unloading by Crane (Recommended for Heavy or Complex Modules) Use a mobile crane or overhead […]
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 […]
Turning Coal Ash into Opportunity: New Pilot Plant and Jobs Initiative in Pennsylvania
A new industrial initiative in Western Clinton County is gaining attention as Anesidora Enterprise advances a project expected to create 10–50 local jobs, with a strong focus on next-generation mineral processing. In partnership with Avimetal, the project will begin with a 10 tons-per-day (TPD) pilot plant, utilizing coal ash as a primary feedstock—reframing industrial waste […]
