Ferromanganese ore beneficiation tailing waste utilization method
The invention discloses a ferromanganese ore beneficiation tailing waste utilization method, which comprises the following steps of: A, grinding ferromanganese ore beneficiation tailings, and sampling the ferromanganese ore beneficiation tailings for test and analysis; B, selecting the ferromanganese ore beneficiation tailings with the iron oxide content within the range of 21% +/-2%; C, adjusting the ferromanganese ore tailings to serve as iron correction raw materials; D, analyzing physical properties and chemical components of raw materials of ferromanganese, calculating a raw material ratio by adopting a cut-and-try method, determining the values of three ratios of clinker, a liquid phase amount and raw materials, and mixing, the use amount of sandstone being reduced due to the fact that tailings contain relatively high SiO; E, firing the mixture by using a dry-method rotary kiln process until a clinker is obtained; and F, producing calcined cement clinker prepared from tailings. According to the design, the clinker produced by adopting the ferromanganese ore beneficiation tailing raw material is good in effect, the raw material is good in burnability, the output per machine hour of a raw material mill and a kiln and the strength of the clinker are obviously improved, and coal consumption and power consumption are reduced to some extent.
本发明公开了一种锰铁矿选矿尾渣废物利用方法，包括如下步骤；A、对锰铁选矿尾渣进行粉磨处理，锰铁选矿尾渣取样进行了化验分析；B、选取中氧化铁含量在21%±2%范围内的锰铁矿选尾渣；C、通过对上述的锰铁矿尾渣调整作为铁质校正原料；D、锰铁通过对原料的物理性质和化学成分的分析，采用试凑法计算原料配比，确定熟料三率值、液相量以及生料并混合，其中由于尾渣中含有较高的SiO，因此减少砂岩的使用量；E、将上述混合料使用干法旋窑工艺烧制直至成熟料；F、尾渣配制煅烧水泥熟料生产；本设计采用锰铁矿选矿尾渣生料生产的熟料效果良好，生料的易烧性较好，生料磨和窑的台时产量及熟料的强度明显提高，煤耗和电耗都有所降低。
