Abstract

The invention discloses a waste red miscellaneous copper refining agent and application thereof, and relates to the field of metal smelting. A waste copper refining agent, comprising chemical components in parts by weight: 3.8-5.3 parts of B, 4.0-4.8 parts of Mg, 8.5-11 parts of Ce, 6.5-7.5 parts of Pr, characterized in that it also includes chemical The parts by weight of the components are: 2-5 parts of Y and 2-5 parts of La. The application of a refining agent for waste red miscellaneous copper includes: adding waste red miscellaneous copper into a reverberatory furnace for smelting, and the reverberatory furnace adopts a combustion control system for heat supply, and the temperature of the control liquid is kept at 1155-1165°C; The copper liquid is removed, deoxidized, and purified; the purified copper liquid is placed in a standing furnace for standing still and then deoxidized. The advantages and beneficial effects of the present invention: Y and La elements are added to the refining agent formula for synergistic modification, and the prepared compound refining agent can improve the impurity removal effect of red copper; the thermal cycle design greatly reduces the time required for the process and shortens the reaction cycle.

Description

technical field [0001] The invention relates to the field of metal smelting, in particular to a waste copper refining agent and its preparation method and application. Background technique [0002] With the rapid development of the national economy, my country's demand for copper and copper alloy products is increasing. At present, my country has become the world's largest copper consumer, with copper consumption accounting for 40% of the world's total. However, my country's copper resources are very scarce, and the reserves of copper resources only account for 5% of the world's total. We must rely on imported copper concentrates, electrolytic copper, copper materials and scrap copper to obtain metallic copper, and the cost is relatively high. In fact, copper is a metal material with good regeneration performance. Improving and improving the recycling technology of scrap copper is an effective way to alleviate the shortage of copper resources. [0003] Red miscellaneous co...
