Many businesses struggle to recover rare earth metals using outdated, wasteful methods — causing environmental damage, resource waste, and regulatory risks. TYIC solves this by offering eco‑friendly hydrometallurgical recycling solutions.
TYIC’s advanced hydrometallurgy delivers efficient, corrosion‑resistant extraction of rare earth elements, enabling lithium battery, magnet, and industrial metal recyclers to meet sustainability and compliance standards while reducing chemical consumption and waste.
Discover how this innovative approach transforms rare earth recovery with minimal environmental impact and maximum operational efficiency.

Why Traditional Methods Fall Short
Conventional rare earth recovery often relies on high‑temperature pyrometallurgy or mechanical separation — both of which demand substantial energy input and produce hazardous by‑products. These processes generate large volumes of slag, emit harmful gases, and carry serious risks of chemical waste leakage. As regulators tighten environmental standards worldwide, reliance on such methods may lead to costly fines, extended downtime, and reputational damage.
Recycling companies may also face inefficiencies: incomplete metal recovery, high operating costs, and difficulties handling mixed-material waste streams (e.g., spent lithium‑ion batteries, industrial scrap containing multiple rare earths). Over time, these inefficiencies erode profit margins and hinder sustainable growth.
The Promise of Hydrometallurgical Recycling
Hydrometallurgy — a water‑based chemical extraction method — offers a cleaner, more controlled alternative. At the core, ore or scrap is treated with specially formulated leaching solutions under moderate temperature and pressure, dissolving target metals. The resulting solution is processed to selectively precipitate and purify rare earth oxides or salts.
Key Advantages
-
Environmentally responsible: significantly lower emissions of gases and particulates compared to pyrometallurgy; reduced risk of slag or solid waste contamination.
-
Energy efficient: operates at ambient or moderately elevated temperatures, cutting energy costs by 40–60%.
-
High recovery rates: often over 90 % of rare earth elements can be recovered, even from complex, mixed-material waste streams.
-
Selective separation: tailored reagents allow precise separation of individual metals (e.g., neodymium, praseodymium, dysprosium), enabling high-purity products.
-
Compliance ready: meets stringent international environmental and safety regulations, facilitating export to Europe, North America, and other regulated markets.
How TYIC Delivers Industrial‑Grade Hydrometallurgy
At the forefront of clean‑tech manufacturing, Hangzhou Tianyicheng New Energy Technology Co., Ltd. (TYIC) integrates advanced hydrometallurgical design, precision fabrication, and turnkey installation to supply clients with complete industrial recycling solutions. TYIC’s offering includes:
-
Custom process design: engineering tailored leaching, separation, and purification workflows based on feedstock composition (e.g., battery scrap, magnets, industrial ore).
-
Corrosion‑resistant equipment: fabrication of high‑grade stainless steel or lined reactors, tanks, and piping — ensuring durability under acidic or alkaline leaching conditions.
-
Efficient mixing and interface systems: specialized tubular mixing extractors and micro‑interface oil removal units optimize reagent contact and phase separation, enhancing yield.
-
Wastewater and waste‑gas treatment modules: built‑in environmental protection units treat effluents and emissions to meet stringent discharge standards, minimizing ecological footprint.
-
Turnkey EPC services: from procurement to installation and commissioning — TYIC handles full project delivery, reducing operational risk for clients.
This suite of capabilities enables recyclers — whether working with lithium‑ion battery waste, permanent magnets, or rare earth ores — to adopt hydrometallurgical recycling without in‑house R&D or fabrication investment.
Real-World Applications and Industry Impact
♻️ Battery & Magnet Recycling
As demand surges for electric vehicles (EVs) and renewable‑energy storage, spent lithium‑ion batteries and decommissioned permanent magnets have rapidly grown as waste streams containing valuable rare earths (e.g., neodymium, dysprosium). Using TYIC’s hydrometallurgical solutions, recyclers can extract and purify these metals efficiently — recovering critical resources while avoiding hazardous waste accumulation. This circular‑economy approach reduces reliance on primary mining and supports sustainable EV supply chains.
🌍 Heavy Industry & Non‑Ferrous Processing
Industrial clients processing nickel, cobalt, manganese, or other non‑ferrous metals often generate by‑product streams containing trace rare earths or mixed-metal residues. Through customized hydrometallurgical treatment, TYIC enables recovery of these rare earths to high purity — turning waste into valuable, reusable material, improving resource efficiency, and lowering raw material procurement costs.
🏭 Environmental Compliance & ESG Value
With global regulators and investors increasingly emphasizing Environmental, Social, and Governance (ESG) criteria, clean recycling processes become a business imperative. TYIC’s solutions allow companies to meet strict emission and waste‑discharge standards through integrated wastewater and waste‑gas treatment systems. This enhances regulatory compliance, reduces long-term liabilities, and demonstrates a commitment to sustainability.
