Method for preparing bricks by smelting copper-containing dangerous solid waste and method for preparing black copper
The invention belongs to the technical field of smelting furnace blowing and non-ferrous metal recycling, and particularly relates to a method for smelting copper-containing dangerous solid waste to make bricks and a method for making black copper. The invention provides a method for preparing bricks by smelting copper-containing dangerous solid wastes. The method is characterized in that carbon-containing auxiliary materials such as waste cathode carbon block powder, waste tire powder and oil sludge are added to prepare the copper-containing bricks. The copper-containing brick has the advantages that in the high-temperature smelting process, the heating reaction is fast, the impurity removal effect is obvious, the copper content of a slag phase is low, the smelting capacity of a unit hearth of a smelting furnace is increased, the effects of reducing carbon and saving energy are achieved, the purity of a black copper product is improved and the like, residues are subjected to water quenching, and the water-quenched residues serve as raw materials of a cement plant.
本发明属于冶炼炉吹炼、有色金属资源化技术领域，具体涉及一种含铜危固废熔炼制砖的方法以及制黑铜的方法。本发明提供了一种含铜危固废熔炼制砖的方法，其通过添加废阴极炭块粉、废旧轮胎粉和油泥等含碳的辅料制作得到含铜砖块。该含铜砖块在高温熔炼过程中具有升温反应快、除杂效果明显、渣相含铜低、增大熔炼炉的单位炉床的熔炼能力、同时达到降碳节能效果和提高黑铜产品的纯度等优点，并对其残渣进行水淬，水淬渣作为水泥厂原料。
