Eco-Friendly Metal Extractant is high-efficient safe green chemical reagent for metal separation purification mining metallurgy and complex industrial wastewater treatment applications.

Eco-Friendly Metal Extractant

Introduction: 

The eco-friendly metal extractant is a new type of green chemical product developed based on cutting-edge molecular design concepts. It is specifically designed for metal separation, purification, and wastewater treatment, and is widely used in hydrometallurgy, precious metal recovery, electronic waste treatment, and industrial wastewater purification. It addresses the industry’s pain points associated with traditional extractants—high pollution, high consumption, and limited compatibility—by balancing high-efficiency separation performance with environmental compliance requirements. This product helps enterprises achieve a transition to green production, aligns with national environmental policies and industry sustainability trends, and serves as the core chemical agent for achieving “cost reduction, efficiency improvement, and environmental compliance” in the modern chemical industry.

Product Features:

Environmental Attributes:

Low toxicity and non-hazardous, safe and user-friendly: The product is low-toxicity and environmentally friendly, with an LD50 ≥ 5000 mg/kg and a permissible concentration in workshop air of ≥ 100 mg/m³. It poses no health risks to operators, allowing normal operations without the need for special protective gear. It contains no heavy metals or highly volatile harmful components, eliminating pollution risks associated with the reagent itself at the source.

Low wastage and easy disposal, environmentally compliant: Designed with low water solubility, the aqueous solubility is ≤16 mg/L at pH 3.0, and the single-use wastage rate is ≤0.09%. This reduces chemical consumption costs while lowering the organic content in wastewater, thereby alleviating the burden on subsequent wastewater treatment; The waste organic phase can be treated via conventional incineration or alkaline hydrolysis without causing secondary pollution, helping enterprises achieve compliant discharge of wastewater and waste residue in accordance with environmental regulations.

Green raw materials, low-carbon and energy-efficient: The production process employs eco-friendly technologies, with recyclable raw materials and no generation of harmful byproducts; no additional heating or cooling equipment is required during use, as optimal extraction results are achieved at room temperature, saving over 30% in annual heating energy consumption and practicing low-carbon production principles.

Performance Characteristics:

1. Strong targeting selectivity and high separation precision: Through precise molecular design, the molecular structure contains specific functional groups such as oxime and hydroxyl groups, enabling precise binding to target metal ions including copper, nickel, cobalt, rare earth elements, gold, and silver, while exhibiting extremely low affinity for impurity ions such as iron, zinc, and aluminum; It offers excellent separation selectivity; in the nickel-cobalt separation system, the selectivity coefficient β (Co/Ni) is ≥125, and the impurity co-extraction rate is ≤1.2%. It can elevate the purity of rare earth products to the 6N (99.9999%) level, with precious metal extraction selectivity ≥99%, achieving deep separation and enrichment of target metals.

2. High extraction efficiency and fast production pace: With excellent kinetic performance, the extraction contact time is only 25–55 seconds, the stripping time is ≤85 seconds, and the phase separation time is ≤110 seconds. Compared to traditional extractants, the process cycle is shortened by more than 50%; Single-pass extraction efficiency is ≥95%, and three-stage counter-current extraction efficiency can reach over 99.5%. Under the same equipment scale, this enables a 50%-70% increase in production line throughput, significantly boosting production efficiency and capacity.

3. Strong chemical stability and long cycle life: It exhibits excellent resistance to acids, alkalis, and oxidation, maintaining stable performance across a wide pH range of 1.5–7.0 and a broad temperature range of –10°C to 60°C. It is resistant to hydrolysis and does not undergo oxidative decomposition; It can be recycled 26–32 times, far exceeding traditional extractants (10–15 times). The decline in extraction efficiency after continuous recycling is minimal, significantly reducing the frequency of reagent replacement and operational costs.

Applications:

Versatile application scenarios: It can be widely used in hydrometallurgy (copper, nickel, cobalt, and rare earth smelting), precious metal recovery (gold, silver, platinum, palladium), electronic waste treatment, purification of industrial wastewater containing heavy metals, and nuclear fuel reprocessing. It is highly adaptable, capable of handling both high-concentration metal leachates and low-concentration dilute solutions for extraction and concentration.

Excellent Equipment Compatibility: It exhibits excellent compatibility with common diluents such as sulfonated kerosene and mineral oil. The organic phase concentration can be flexibly adjusted between 5% and 40% (v/v) according to process requirements. It easily integrates with various industrial extraction equipment, including mixed settling tanks, centrifugal extractors, and extraction towers, enabling “seamless integration” without the need for modifications to existing equipment.

Simple and Easy to Control: At room temperature, it is a clear, transparent, pale yellow to light brown liquid, free of mechanical impurities and odors, facilitating visual operation and quality inspection in the workshop. It can be used directly without additional filtration. The process is convenient to operate with a flexible adjustment range; back extraction can be performed using standard hydrochloric acid or sulfuric acid, eliminating the need for special reagents and reducing operational complexity and control costs.
