众所周知,利用火电厂的煤灰作为生产陶砖的贫化剂和燃料添加剂是大有发展前途的方向。但煤灰作为粗粒分散的材料,不适合生产低塑性黄土质砂粘土的陶制品。在哈萨克斯坦和中亚,砖厂主要用黄土质砂粘土,这是一种低质贫瘠原料,其塑性指数不超过10,因而不能保证砖的耐寒力和强度。本文研究了将锆-钛铁矿重力分选尾矿的粘土部分作为粘土组成的可能性,它是经粉碎和筛选之后得到的,呈泥浆状,湿度37%～45%。这是一种难熔的材料(耐火度1480～ As we all know, the use of coal-fired power plant as a production of pottery clay depleters and fuel additives is a promising direction. However, coal ash as a coarsely dispersed material is not suitable for the production of low plastic loess sand clay products. In Kazakhstan and Central Asia, bricks are mainly loamy sands, a low-quality, poorly-sourced raw material whose plastic index does not exceed 10 and therefore can not guarantee the cold resistance and strength of bricks. In this paper, the possibility of making the clay part of zirconia-ilmenite gravity separation tailings clay as clay is obtained after being pulverized and screened, and it is muddy with a humidity of 37% -45%. This is a refractory material (refractoriness 1480 ~
