1 Scope

GB 25323-2023 is the Chinese national standard on the norm of energy consumption per unit production of nonferrous heavy metals metallurgical enterprises, in the field of energy and heat transfer engineering. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 23 May 2023 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 June 2024. Classification: ICS 27.010, CCS F01. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document stipulates the energy consumption limit level, technical requirements, statistical scope and calculation method of the unit product of non-ferrous heavy metal smelting enterprises: This document is applicable to the calculation and assessment of the energy consumption of the following non-ferrous heavy metal copper, zinc, lead, nickel, tin, antimony, secondary lead, cobalt and bismuth smelting enterprises: And the energy consumption control of new construction and renovation and expansion projects:

a) Copper concentrate, blister copper, miscellaneous copper (including black copper, recycled copper alloy raw materials, recycled copper raw materials, and other copper-containing materials after sorting and removing impurities) etc:) Copper smelting enterprises as raw materials: Not suitable for copper smelters dealing with copper-containing hazardous waste (such as copper-containing sludge, copper-containing fume) technology, copper-bearing material leaching electrowinning process and copper-bearing ore direct heap leaching process:
