Metalcess Intelligent provides turn-key solution package for the Copper extraction projects from various types Copper ore to produce LEM grade A Copper cathode, including optimal technological process determination, engineering design, equipment fabrication, guidance for installation and commissioning, and staff training. Copper oxide ore can be directly extracted by leaching process, with no benefication process required to produce Copper concentrate firstly even when the Copper grade is supper low in the ore. Heap leaching and tank leaching are two major leaching process applied in industrial scale, followed by solvent extraction and electro-winning to produce cathode Copper. Copper Sulfide ore will firstly be treated with flotation process to be enriched as qualified Copper concentrate. For large capacity project, smelting furnace (TSL, Copper matte)-PS convertor (crude Copper)-Anode furnace (anode copper) -Electro-refining(cathode copper) would be suggested especially when there is Gold in the ore. Fluidized bed furnace - leaching -SX-EW is more suggested for medium project as it as lower investment, while high pressure oxygen leaching process is applied for Copper sulfide ore small scale project.

The pyrometallurgical extraction process of platinum group metals(PGMs) from spent automobile catalyst supplied by Metalcess in China is using electric furnace smelting combined with TBRC furnace blowing. After electric furnace smelting, the platinum group metals can be enriched from 0.2-0.3% to 2-3%.By TBRC furnace blowing, the platinum group metals can be further enriched by 10-20times to 20-30%. This process can reduce industrial wastewater output by 90% compared to directly entering the hydrometallurgical process after electric furnace treatment. The hydrometallurgical wastewater for platinum group metals cannot be recycled and must be treated before discharge. Therefore, using the TBRC furnace for catalyst secondary enrichment can significantly reduce wastewater treatment costs for platinum group metal recycling enterprises.

PCB recycling equipment and technology supplied by Metalcess can have a efficient recovery of Copper and precious metals such as Gold and Silver. Pyrometallurgy serves as the primary process in our recycling system. As a Chinese new high-tech enterprise in metallurgy industry, Metalcess can design and manufacture TBRC furnace and TSL furnace. Compared with hydrometallurgical processes, the pyrometallurgical process for PCB recycling achieves a higher recovery rate of precious metals and is more environmentally friendly.

Copper recycling technology and equipment supplied by Metalcess can produce 99.96% cathode Copper from varies Copper scrap(50-95%). Through the process of smelting, converting, and fire-refining, 98.5%-99% Copper anode will be produced, and then by electrolysis 99.99% cathode Copper can be produced. As a China new high-tech enterprise, Metalcess can help small and medium capacity client with the supply of a minimum capacity of 3 ton/batch furnace and 3 ton/day Copper electrolysis system.

Metalcess intelligent offers a comprehensive system for Zinc Calcine Leaching plants to produce high-purity cathode Zinc (99.99%) from zinc oxide calcine derived from Zinc ore, Zinc concentrate, Zinc fume dust, Zinc slag, Zinc ash, and similar materials. There are ammonia leaching, neutral leaching, and high acid leaching, also known as hot acid leaching. Through the process of alkali washing - neutral leaching - hot acid leaching - iron removal - Zinc powder purification - EW, cathode zinc (Zn ≥ 99.99%) can be produced. Hot acid leaching and neutral leaching can be combined process in many plants. From lab-scale, pilot plant to industrial applications, Metalcess can provide optimal process technology and well matched equipment to extract Zinc from ore and dust containing high fluorine and chlorine.

Metalcess Intelligent offers an Ammonium Leaching process for the production of high-purity zinc cathode (Zn ≥ 99.99%) from Zinc oxide materials, including those derived from ores, concentrates, and Zinc-containing smelting by-products such as zinc oxide dust, electric arc furnace (EAF) dust, off-gas dust, etc. The core technological flow consists of "leaching-purification-electrowinning." This process can be tailored for capacities ranging from pilot-scale to industrial applications.

Through blast furnace or oxygen side blow furnace smelting, high nickel matte can be produced from nickel ore or concentrate. Then battery-grade nickel sulfate can be produced from high nickel matte by hydrometallurgical process. Metalcess provides the technology and equipment for producing power battery nickel sulfate from nickel concentrate and nickel ore. The main technical process is: blast furnace/oxygen side blow furnace smelting - sulfuric acid leaching - copper extraction - iron removal by neutralization - cobalt extraction - nickel extraction - MVR concentration - OSL continuous crystallization.

Tin separation can be achieved successfully by Vacuum distillation unit manufactured by Metalcess. Many lead battery scrap recycling plant send harris dross back to rotary furnace and produce Lead-Tin alloy, by VDU/VDF, Lead can be separated from Tin. Tin from soldering Tin, Lead-Tin alloy, and Lead-Tin-Antimony alloy can be separated to produce high purity Tin ingot (99%-99.99%) by the combination of vacuum distillation furnace process, tin fire-refining process and crystallization process. Our Tin and Lead separation technology and equipment has a high recovery rate and high grade output product, which give clients a high economic payback. The production capacity can be 3 tons per day to hundreds tons per day.

Metalcess Intelligent provides Copper Electrolysis (Electro-refining) Plant to produce cathode Copper (Cu≥99.96%) from Anode Copper (Cu≥98%). If the Copper anode has precious metals content, the precious metals will go to anode slime and can be further recovered. The copper electrolysis system provided by Metalcess is the IAS method, which uses permanent stainless steel cathode plates instead of cathodes made from starting sheets. The cathode Copper is stripped from the permanent cathodes. A mini-capacity of 4ton/day Copper stripping system is self-developed by Metalcess to meet small and medium capacity project requirement.
