As core materials in high-end manufacturing, national defense and aerospace, and electronic semiconductors, precious metals (gold, silver, platinum, palladium, rhodium) directly determine an enterprise’s core competitiveness. Currently, with tight supply of low-grade raw materials, high difficulty in recycling renewable resources, surging demand for high purity, and increasingly strict environmental compliance requirements, traditional refining technologies struggle to break through the bottlenecks of “insufficient purity, low recovery rate, and high pollution risk”. With ultra-high temperature plasma core technology ranging from 3,000℃ to 10,000℃, the DC Plasma Furnace reconstructs the logic of precious metal refining, covers full-scenario refining needs, achieves four major breakthroughs of “low consumption, high purity, compliance, and high value”, and becomes the preferred upgrade for the precious metal refining industry.
Full-Scenario Cultivation: Covering the Entire Precious Metal Refining Process, Precisely Tapping Every Bit of Resource Value
With ultra-high temperature melting and precise separation capabilities, the DC Plasma Furnace breaks the limitations of traditional equipment in material adaptation, covers four core scenarios of precious metal refining, adapts to various raw materials, maximizes resource potential, and meets the refining needs of enterprises of different sizes.
✅ Enrichment and Refining of Low-Grade Ore/Tailings
For low-grade gold, silver, platinum group metal ores and tailings, traditional technologies are difficult to achieve efficient enrichment, leading to resource waste. Relying on an ultra-high-temperature plasma torch, the DC Plasma Furnace can quickly melt precious metals in ores. Through precise temperature control and optimized metallurgical processes, it greatly improves the grade of precious metals, converting “low-value lean ore” into “high-value refining raw materials”. It effectively reduces enterprises’ dependence on imported high-grade ores, reduces raw material procurement costs, and realizes the efficient utilization of low-grade resources.
✅ High-Value Recovery and Refining of Renewable Resources
Renewable resources such as waste circuit boards, automotive catalytic converters, waste batteries, and spent catalysts have complex compositions and high impurity contents. Traditional refining technologies have low recovery rates and are prone to secondary pollution. The DC Plasma Furnace can handle various types of precious metal-containing renewable waste in one stop. Its ultra-high temperature completely decomposes organic impurities and separates non-metallic carriers, accurately recovering precious metals such as gold, silver, platinum, and palladium with a recovery rate of over 99%. With no smoke or leachate pollution throughout the process, it realizes “turning waste into value” for renewable resources, conforming to the trend of green circular development.
✅ Ultra-High Purity Precious Metal Refining and Preparation
Fields such as high-end electronics, national defense and aerospace, and precision instruments have strict requirements on precious metal purity (needing to reach above 99.99%). Traditional refining technologies are difficult to remove trace impurities and cannot meet high-end market access standards. Through ultra-high temperature melting and precise temperature control technology, the DC Plasma Furnace can deeply remove trace non-precious metal impurities such as copper, lead, and iron from raw materials, realizing ultra-high purity refining of precious metals. The purity of finished products can reach 99.99%-99.999%, perfectly adapting to the quality requirements of high-end industries, helping enterprises break market barriers and seize the high-end track.
✅ Synergistic Treatment of Hazardous Waste Containing Precious Metals
For hazardous waste containing precious metals such as electroplating sludge, chemical hazardous waste, and spent catalysts, traditional treatment methods are difficult to balance “harmless treatment” and “resource recovery”, which easily leads to precious metal loss and environmental pollution. The DC Plasma Furnace adopts a fully enclosed micro-negative pressure operation mode. Its ultra-high temperature completely decomposes organic toxins in hazardous waste and fixes heavy metals, realizing harmless treatment of hazardous waste. At the same time, it recovers the precious metals synchronously, converting “high-risk hazardous waste” into “high-value resources”, balancing the dual values of environmental compliance and resource recovery, and adapting to the requirements of strict environmental regulations.
Core Advantages: Breaking Through Pain Points in the Precious Metal Refining Industry with Technological Innovation
Relying on independently developed plasma core technology and integrating the advantages of DC drive control, the DC Plasma Furnace forms an absolute barrier in efficiency, purity, environmental protection, cost and other aspects compared with traditional refining equipment, accurately solving the core pain points of the industry.
✅ Ultra-High Temperature Core, Unmatched Melting Capacity
Equipped with an ultra-high-temperature plasma torch ranging from 3,000℃ to 10,000℃, its temperature is much higher than that of traditional electric arc furnaces. It can quickly melt various refractory materials (including low-grade ore, refractory impurities, and hazardous waste carriers), completely breaking the limitations of traditional equipment such as “incomplete melting and difficult impurity separation”, laying a foundation for efficient refining, greatly shortening the refining cycle, and improving production efficiency.
✅ High Purity Refining, Quality Meeting High-End Standards
Equipped with a high-precision temperature control system (temperature control accuracy ±5℃), it can precisely control the redox reaction during the melting process and deeply remove trace impurities from raw materials. The purity of precious metals can reach above 99.99%, and some precious metals can achieve ultra-high purity preparation of 99.999%, fully meeting the quality requirements of high-end manufacturing, national defense and aerospace and other fields, and increasing product added value.
✅ High Recovery Rate, Maximizing Resource Value
With ultra-high temperature precise separation technology, the precious metal recovery rate is as high as over 99%, 12%-18% higher than traditional refining technologies. Whether it is low-grade ore, renewable waste or hazardous waste containing precious metals, it can achieve “zero omission” recovery of precious metals, maximize the potential value of resources, and directly increase the profit space of enterprises.
✅ Compliance and Environmental Protection, Pollution-Free and Worry-Free Production
Adopting a fully enclosed melting system + micro-negative pressure operation mode, it can efficiently capture 99.8% of smoke and harmful gases. The ultra-high temperature completely decomposes dioxins, heavy metals and other toxic substances. The particulate matter emissions and flue gas opacity all meet strict environmental standards. There is no leachate or waste gas emission throughout the process, and no additional environmental protection equipment is needed, helping enterprises avoid compliance risks and realize green and low-carbon production.
✅ Energy Saving and Cost Reduction, Adapting to High-Cost Operating Environment
Adopting high-efficiency DC drive technology, power loss is reduced by more than 25%, electrode consumption is reduced by 40%, and the natural power factor of the equipment reaches 0.96-0.99, eliminating the need for additional reactive power compensation devices, and greatly saving equipment procurement and later maintenance costs. Long-term operation can reduce the refining cost by 18%-22%, significantly shorten the investment payback period, and adapt to the operating scenarios of high electricity prices and high environmental protection costs.
✅ Flexible Adaptation, Reducing Enterprise Investment Risks
It supports full-capacity customization from 50kVA to 30,000kVA, which can adapt to full-scenario needs such as small-scale laboratory refining, medium-scale renewable resource refining of enterprises, and industrial large-scale ore/hazardous waste treatment. No large-scale plant renovation is required, and process parameters can be flexibly adjusted according to material composition and processing capacity, effectively reducing the initial investment risk of enterprises and adapting to the development needs of enterprises of different sizes.
