Technical Guidelines for Circular Economy Practice in Copper Smelting Industry

1 Scope

This standard specifies the basic principles for the development of circular economy in the copper smelting industry, the circular industry chain, the types of recyclable resources, and the recycling Ways and practical techniques of circular economy. This standard applies to the circular economy practice of copper smelting enterprises that use copper concentrate, blister copper, and waste copper as raw materials. This standard does not apply to the circular economy practice of copper smelting enterprises that adopt the direct heap leaching process of copper-containing ore.

4 basic principles

4.1 The principles of reduction, resource utilization and reuse shall be followed, and the consumption of raw and auxiliary materials, as well as coal, natural gas and electric energy shall be reduced through technical integration. Improve the resource utilization level of waste heat and energy of flue gas and solid waste and by-products such as tailings, soot, anode sludge, etc., and realize the internal resources and energy of the industry. Maximize source utilization efficiency. 4.2 It should cover the main processes of smelting, blowing, fire refining, electrolytic refining and other major processes of resources, efficient use of energy and recycling of renewable resources, etc. The main link of circular economy.

5 Circular industry chain

The schematic diagram of the circular economy industrial chain of the copper smelting industry is shown in Figure 1.Among them, the main processes such as smelting, blowing, fire refining, and electrolytic refining are constituted The main part of the circular economy industry chain, sulphuric acid production from flue gas, waste heat and waste energy utilization, waste water reuse, solid waste and by-product comprehensive utilization constitute a cycle The extended part of the economic industry chain.
