Irresistible Nickel: Xiamen Xiadias' Technological Applications and Industry Solutions in Nickel Resource Extraction and Powder Purification
Release time:
2025-05-21
Introduction: The Surge of Nickel, Prioritizing Purification
Nickel, an irreplaceable core metal in electric vehicle batteries and stainless steel production, is at the forefront of a new round of global energy structural transformation. According to data from the International Nickel Study Group (INSG), global nickel demand is growing at a rate of nearly 8% per year. Especially with the rapid development of new energy vehicles, the strategic importance of high-purity nickel is becoming increasingly prominent.
In the process of resource extraction and metal extraction, "impurities" are nickel's biggest enemy. Laterite nickel ores, sulfide nickel ores, and later wet metallurgy and precursor synthesis processes all produce a large amount of difficult-to-handle solid-liquid mixtures, colloids, impurity metal ions, and micron-nanometer-scale particles. How to efficiently and stably complete solid-liquid separation and purification is a key hurdle to high-purity nickel materials.
Xiamen Xiadias Filtration Materials Technology Co., Ltd., as a technology leader in the field of filtration materials and equipment in China, is providing key support for nickel resource extraction and material purification through advanced industrial filter cloths, filtration equipment, and system solutions. This article will focus on the nickel industry chain, starting from industry pain points, and analyze Xiadias' technological advantages and implementation plans in powder filtration, impurity separation, and equipment integration.
■ Nickel's Strategic Position and Industry Chain Structure
Nickel resources mainly come from two forms: laterite nickel ore and sulfide nickel ore. Laterite nickel ore is mainly distributed in Southeast Asia, the South Pacific, and other regions, suitable for hydrometallurgy (HPAL, reduction roasting-ammonia leaching, etc.); while sulfide nickel ore is often extracted through pyrometallurgy or bioleaching.
From ore mining to high-purity nickel salts, the nickel industry chain is roughly divided into:
Ore Processing Stage : Ore crushing, grinding, flotation or acid leaching
Hydrometallurgical Extraction Stage : HPAL (high-pressure acid leaching), reduction leaching, solvent extraction, precipitation
Precursor Synthesis Stage : Nickel cobalt manganese (NCM) or nickel cobalt aluminum (NCA) precursors are prepared by coprecipitation
Terminal Material Stage : After roasting and sintering, battery-grade high-nickel ternary materials are formed
In this chain, every link is inseparable from efficient and precise Solid-liquid separation technology . Industrial filter cloth and filtration equipment are important carriers for "extracting" and "purifying" nickel from the ore.
■ Industry Pain Points: From "Obtainable" to "Pure"
With the iteration of industry chain technology, nickel extraction faces the following challenges:
1. High concentration, strong corrosive slurry solid-liquid separation is difficult
In the hydrometallurgical extraction process, high-pressure acid leaching (HPAL) is often accompanied by high temperature (>250℃), high pressure, and strong acid (H ₂ SO ₄ ) environment. The resulting slurry has high viscosity and strong corrosiveness, and traditional filter cloths are easily blocked, passivated, and have a short lifespan.
2. Difficult to control impurity content, affecting precursor quality
The synthesis of precursors requires extremely strict control of impurities (Fe, Ca, Al, Mg, etc.), and traditional filtration methods often cannot achieve efficient removal of micron-level or even nano-level impurities.
3. Poor filter cloth compatibility and insufficient equipment adaptability
Currently, most enterprises face the problem of "neither here nor there" with equipment domestication and filter cloth import dependence. The matching degree between the filter cloth structure and the filter press is low, resulting in low separation efficiency and high maintenance costs.

4. Powder purification standards are improving, and systematic solutions are urgently needed
With the increasing demand of the new energy industry for high-purity nickel powder and consistent morphology of precursors, single filtration materials or equipment can hardly meet the needs of industrial upgrading, and integrated innovation of "materials + equipment + technology" is urgently needed.
■ Xiadias' Technological Practices and Solutions in the Nickel Industry
In the extraction and processing of nickel resources, solid-liquid separation technology not only ensures the continuity of the process, but also directly affects the metal recovery rate and environmental protection compliance rate. Xiamen Xiadias Filtration Materials Technology Co., Ltd., with more than 30 years of experience in the field of filtration materials, has provided mature filtration solutions in many key links of the nickel industry chain.

In the solid-liquid separation process of complex working conditions such as nickel smelting tailings, steel slag slurry, and sintering desulfurization gypsum, Xiadias industrial filter cloths have shown excellent chemical corrosion resistance, stripping performance, and filtration accuracy, and are widely used in:
Dehydration and reprocessing of nickel tailings and steel slag tailings;
Efficient dehydration of ball mill workshop slurry and sintering desulfurization by-products (such as gypsum) in the nickel iron smelting industry;
Recovery and purification of nickel-containing materials such as steel slag slurry and slag ash in stainless steel and nickel-chromium-iron alloy enterprises;
Metal re-extraction process in nickel processing to maximize residual nickel recovery rate.

In these highly complex scenarios, Xiadias customizes filter cloth structures and processing technologies for different machine types (such as horizontal vacuum belt filters, belt press filters, filter presses, drum filters, etc.) to ensure stable system operation, good filter cake formation, and longer filter cloth life under extreme conditions such as strong acids and alkalis, strong shear, and fine particle separation, thereby helping customers improve overall economic efficiency and green production levels.
■ New type of nano-micrometer powder filter aids the development of nickel-based new materials industry
With the development of new energy, battery materials and high-performance alloys, the purity and particle control requirements of nickel-based powder materials are constantly improving. The new nano-micrometer powder filter innovatively launched by Xiadias is the key equipment to cope with this industrial upgrading.
This equipment, through the combination of modular structure and high-precision filtering components, has been successfully applied to the filtration of various micro-nano materials, including nano-nickel powder and nickel oxide. It is widely applicable to:
Nano-scale metal powders (such as nickel powder, silver powder, zinc powder, aluminum powder, iron powder, zirconium powder, titanium powder);
Oxide powders (such as nickel oxide, zinc oxide, aluminum oxide, iron oxide, titanium oxide);
Fine inorganic powders (such as calcium carbonate, silicon dioxide, silicon carbide, etc.) for grading and purification, solid-liquid separation and end drying.
Especially in the preparation of nickel powder and nickel oxide powder, The new equipment has a retention rate as high as 99.9%, All-physical filtration process, no need to add any chemicals or auxiliaries. Integrated process design, integrating solid-liquid separation, washing and drying significantly improves filtration efficiency and product purity, helping customers build competitive barriers in the high value-added materials market. At the same time, the equipment has a high degree of automation, small footprint, and low energy consumption, adapting to the layout needs of modern green factories.
■ Conclusion: “Nickel” future, let’s purify together
The extraction of nickel resources is not only an industrial leap from "mine to material", but also a comprehensive challenge to fine processes, high-end equipment and materials science. Xiamen Xiadias, as a leading enterprise in China's filtration system field, is providing a solid technological foundation for the nickel industry chain through technological innovation and industry cultivation.
"Purification is for a purer future." In the wave of new energy vehicles, battery materials, and green metallurgy, Xiadias is willing to work hand in hand with industry colleagues, using every piece of filter cloth and every piece of equipment to promote the nickel industry to go further and more steadily.
