Gold tailing unfired lightweight ceramsite and preparation method thereof
The invention discloses gold tailing unfired lightweight ceramsite and a preparation method thereof. According to the technical scheme, 50%-80% by mass of gold tailings, 10%-50% by mass of cement, 0%-20% by mass of quick lime and a proper amount of water are fed into a stirring machine to be evenly mixed, slurry is prepared, foam is prepared from a cement foaming agent through a foaming machine, the foam and the slurry are evenly mixed, foam slurry is prepared, then the foam slurry is poured into a spherical mold with a certain inner diameter, and the spherical mold with the certain inner diameter is formed. After natural curing is conducted for a proper time, mold removal is conducted, porous pellets are obtained, the porous pellets are subjected to steam curing or autoclaved curing, a ceramsite semi-finished product is obtained, the ceramsite semi-finished product is soaked in an acrylic acid waterproof coating and taken out, and the unfired light ceramsite is obtained. The method has the advantages that the process is simple, the production cost is low, energy is saved, the environment is protected, massive harmless and full-resource utilization of the gold tailings is realized, the unfired lightweight ceramsite with small water absorption and good sphericity can be prepared, the density grade and the ceramsite particle size are flexible and convenient to adjust, the economic benefit is good, the environment-friendly benefit is good, and the like.
本发明公开了一种黄金尾矿免烧轻质陶粒及其制备方法。该技术方案是将质量分数为50%~80%的黄金尾矿,10%~50%的水泥,0%~20%的生石灰以及适量水,送入搅拌机混合均匀,制得料浆,水泥发泡剂经过发泡机制得泡沫,将泡沫与料浆混合均匀,制得泡沫料浆,再将泡沫料浆浇注入一定内径的球形模具,自然养护适当时间后,拆模,得到多孔球粒,多孔球粒再经蒸汽养护或蒸压养护,得到陶粒半成品,将陶粒半成品在丙烯酸防水涂料中浸渍,取出得到免烧轻质陶粒。本发明工艺简单、生产成本低,节能环保,实现黄金尾矿的大宗无害化和全资源化利用,可以制得吸水率小、球形度好的免烧轻质陶粒,且密度等级和陶粒粒度大小调节灵活方便,经济效益良和环保效益良好等优势。
