1 Scope

GB 32032-2024 is the Chinese national standard on norm of energy consumption per unit production for gold mining, mineral processing, metallurgy and refining of gold, 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 29 April 2024 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 May 2025. 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 specifies the technical requirements, statistics and quotas for energy consumption per unit product (hereinafter referred to as energy consumption) for gold mining, metallurgy and gold refining: Scope and calculation method: This document is applicable to the calculation and assessment of energy consumption per unit product of gold mining, beneficiation and refining, as well as the energy consumption of new or expanded projects: Consumption control:
