Technical specifications for collection and recovery of non-
ferrous metal contained solid waste
1 Scope
This Standard specifies general requirements for recovery of non-ferrous metal
contained solid waste, enterprise management requirements, ecological environmental
protection requirements and recycling product management requirements.
This Standard is applicable to recovery of solid wastes such as residues, dust, smoke,
sludge and waste liquid that contain non-ferrous metals produced in ferrous metal
smelting, non-ferrous metal smelting, electronics industry, metal surface treatment,
petroleum refining, environmental treatment and other industries.
This Standard is not applicable to the recovery of solid waste generated during mining
and beneficiation in the non-ferrous metal industry. It is not applicable to the recovery
of solid waste that contains radioactive material.
2 Normative references

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
technology. Adopt comprehensive utilization and environmental protection
technologies encouraged and recommended by the state. Timely measure and monitor
environment and energy. Timely detect and eliminate adverse effects on the
environment.
5.4 During transportation and storage of semi-solid and liquid non-ferrous metal
contained solid wastes, they shall be loaded into special barrels, tanks and other
containers or tank trucks. The storage and transportation of non-ferrous metal contained
solid waste shall comply with the requirements of GB 18597, HJ 2025 and other
standards.
6 Enterprise management requirements
Enterprises that recycle non-ferrous metal contained solid waste shall meet the
following basic requirements:
a) It belongs to the enterprise legal person qualification established in accordance
with the law and has the business scope of comprehensive utilization of non-
ferrous metal solid waste.
b) Management personnel, professional technicians, skilled workers and other
personnel suitable for the scale of the organization and the type of comprehensive
utilization of non-ferrous metal solid waste shall be deployed. Relevant staff and
management personnel shall master the provisions of relevant national policies,
regulations, and standards.
c) There shall be a fixed place and necessary recycling, storage, processing and
environmental protection and safety facilities and equipment, which meet the
requirements of national or local environmental protection and safety protection
related standards and specifications.
d) There shall be a sound management system or management system for personnel
management, production management, quality management, safety emergency
management and environmental management.
e) The amount of solid waste to be treated shall be compatible with the recycling
capacity and pollution prevention and control capacity.
7 Common recycling technologies
7.1 Physical processing
It is a treatment method, that is according to the basic physical properties of non-ferrous
metal contained solid waste, changes the morphology of solid waste by physical
methods without destroying the composition of solid waste, including compaction,
crushing, screening, sorting, dehydration, evaporation, extraction, adsorption and other
methods. Before recovery, the necessary initial treatment of non-ferrous metal
contained solid waste can be carried out, mainly including crushing, sorting and other
processes. For non-ferrous metal contained sludge and semi-solid waste residues,
mechanical dehydration can be carried out by means of pressure filtration or drying and
dehydration can be carried out using equipment such as thermal ovens and steam drying
ovens.
7.2 Chemical treatment
It is a treatment method, that is according to the basic chemical properties of non-
ferrous metal contained solid waste, undergoes chemical transformation to obtain
valuable metals or metal compounds and other substances, including redox, electrolysis,
electrowinning, extraction, separation, leaching and other hydrometallurgical methods,
and roasting, smelting and other pyrometallurgical methods. See Annex A for the
typical utilization process of non-ferrous metal contained solid waste.
7.3 Biological treatment
It is a treatment method that uses biochemical action to treats non-ferrous metal
contained solid waste to obtain valuable substances or energy, such as microbial
metallurgy.
8 Ecological and environmental protection requirements
8.1 Construction requirements
The site selection of the recovery of non-ferrous metal contained solid waste shall meet
the requirements of the ecological protection red line. Combining with the status quo
of environmental quality and related planning and functional zoning requirements,
determine the environmental quality objectives and the corresponding environmental
management and control, pollutant discharge control requirements. The project shall be
able to maintain stable environmental quality and shall not be lower than the
environmental quality standards for air, soil and water. The project shall build
supporting environmental protection facilities in accordance with the requirements of
environmental protection "three simultaneous” and apply for environmental protection
acceptance upon completion of the project according to law.
8.2 Pollution control requirements
8.2.1 In the process of recycling non-ferrous metal contained solid waste, the discharge
of air, water and solid pollutants shall meet the requirements of national and local
pollutant discharge standards.
8.2.2 The waste residue generated in the process of treatment and disposal shall be
identified according to the provisions of GB 34330 and GB 5085 (all parts), and shall
meet the following provisions:
a) Those identified as hazardous wastes shall be collected, stored and transported
according to the requirements of GB 18597 and HJ 2025, and shall be handed
over to qualified units for processing.
b) If it is identified as general industrial solid waste, it shall be further processed and
utilized, or stored or landfilled in accordance with the requirements of GB 18599.
8.3 Resource utilization requirements
Enterprises that recycle non-ferrous metal contained solid waste shall take energy-
saving and emission-reduction measures, so as to reduce energy consumption, improve
wastewater recycling rate, and minimize new water consumption. The recycling rate of
valuable resources shall be continuously improved. The heat energy generated during
the recycling process is utilized in an appropriate form.
9 Recycling product management requirements
9.1 Comprehensive utilization requirements
9.1.1 Recycling products of non-ferrous metal contained solid waste, when they comply
with the quality standards of products produced by substituted raw materials established
by the state, local or common in the industry, shall meet the technical standards for the
prevention and control of environmental pollution by solid waste, the subsequent
environmental management requirements and the technical requirements of
downstream industries. If there is a stable market demand, the recycling products shall
be managed according to the products.
9.1.2 Metal enrichment obtained after chemical leaching, precipitation, dehydration and
drying, if can be used as raw and auxiliary materials for downstream industries, shall
be managed with reference to the requirements for the corresponding raw and auxiliary
materials.
9.1.3 Recycling and processing products of non-ferrous metal contained solid waste, if
they meet the requirements of the comprehensive utilization standard of solid waste and
the pollution prevention and control standard and at the same time meet the technical
requirements of the user, can be used as an additive for the preparation of building
materials, or as a raw material or ingredient for making lightweight aggregates, ceramic
materials, magnetic materials.
9.2 Final disposal requirements
9.2.1 Treatment and disposal products of non-ferrous metal contained solid waste, if
they do not meet national or industry standards for related products and have no stable
market demand, are managed as solid wastes. If they are determined to be hazardous
