Method for preparing clinker cement through cooperation of suspension roasting gold smelting cyanide slag and red mud
The invention discloses a method for preparing clinker cement by cooperation of suspension roasting gold smelting cyanide slag and red mud, and belongs to the field of preparation and processing of special cement materials. The method comprises the following specific steps: (1) carrying out magnetizing roasting on the gold smelting cyanogen slag by adopting a suspension roaster to extract iron; (2) iron ore concentrate is separated through magnetic separation; (3) proportioning the magnetic separation tailings and the red mud according to preset mineral composition, and preparing a cement raw material with ingredients such as an aluminum material and limestone; (4) sintering at high temperature by using a suspension roaster to obtain clinker cement; and (5) cooling the product, grinding, and mixing with gypsum to prepare the sulphoaluminate cement. According to the method, the gold smelting cyanogen residues can be subjected to harmless treatment, and the cyanogen removal rate is larger than 99%; and the iron in the gold smelting cyanogen slag can be fully and resourcefully utilized. In addition, through collaborative roasting of the red mud, the use of lime and aluminum materials is reduced, meanwhile, the direct utilization rate of the red mud is increased, and energy consumption and consumption of natural resources are reduced.
一种悬浮焙烧黄金冶炼氰渣协同赤泥制备熟料水泥的方法，属于特种水泥材料制备加工领域。具体步骤为：(1)采用悬浮焙烧炉对黄金冶炼氰渣进行磁化焙烧提铁；(2)通过磁选选别出铁精矿；(3)将磁选尾矿协同赤泥按预设矿物组成进行配料，经同铝质材料和石灰石等配料制备水泥生料；(4)用悬浮焙烧炉进行高温烧结获得熟料水泥；(5)产品冷却后进行粉磨处理，与石膏混合制成硫铝酸盐水泥。本发明能够将黄金冶炼氰渣进行无害化处理，除氰率＞99％；并且能够全组分、资源化利用黄金冶炼氰渣中的铁。此外，赤泥的协同焙烧既减少了石灰及铝质材料的使用，同时提高了赤泥的直接利用率，降低了能耗及自然资源的消耗。
