Collaborative copper smelting method and building material
The invention provides a collaborative copper smelting method and a building material, and belongs to the technical field of metallurgy. According to the collaborative copper smelting method, smelting is conducted through a molten pool smelting furnace; collaborative smelting is conducted on collaborative copper smelting materials in a high-temperature stirring molten pool; and crude copper, matte, smoke dust and collaborative copper smelting stabilization smelting slag are obtained. The pre-prepared slag type requirement of the collaborative copper smelting stabilization smelting slag comprises the following elements in percentage by weight: 25-40% of SiO2, less than or equal to 25% of CaO, 15-65% FeO, less than or equal to 10% of Al2O3, less than or equal to 10% of Na2O and K2O, less than or equal to 35% of CaO, Na2O and K2O, less than or equal to 10% of MgO, less than or equal to 5% of Cr2O3 and more than or equal to 85% of CaO, SiO2, FeO, Na2O, K2O and Al2O3; and K is equal to 1-2. The flow temperature N of the collaborative copper smelting stabilization smelting slag is smaller than or equal to the smelting temperature, and the smelting temperature is smaller than or equal to (N + 100 DEG C). The slag obtained by the collaborative copper smelting method has lower acid dissolution rate and copper content, and resource recycling can be directly conducted on the slag.
本申请提供一种协同炼铜方法及建筑材料，属于冶金技术领域。协同炼铜方法以熔池熔炼炉冶炼，在高温搅动熔池中对协同炼铜物料进行协同熔炼，得到粗铜、锍、烟尘和协同炼铜稳定化冶炼渣。协同炼铜稳定化冶炼渣的预配渣型要求包括如下元素含量，以wt％计：25≤SiO2≤40，CaO≤25，15≤FeO≤65，Al2O3≤10，Na2O和K2O≤10，CaO、Na2O和K2O≤35，MgO≤10，Cr2O3≤5，CaO、SiO2、FeO、Na2O、K2O和Al2O3≥85；K＝1～2。协同炼铜稳定化冶炼渣流动温度N≤熔炼温度≤(N+100℃)。该方法得到的渣具有较低的酸溶失率和含铜量，能直接资源化回收利用。
