Abstract
1. Способ комплексной переработки золы отвалов тепловых электростанций, включающий разделение пульпы золы на крупную и мелкую фракции, флотацию и магнитную сепарацию с получением целевых продуктов, заключающийся в том, что крупную фракцию золы отделяют на грохоте для использования в производстве бетонных смесей, мелкую фракцию золы подвергают основной и перечистной флотации, фильтрации и сушке, получая углеродный концентрат, отделенные при основной флотации хвостовые фракции подвергают магнитной сепарации и сушке и получают магнетитовый и алюмосиликатный концентраты, далее алюмосиликатный концентрат измельчают на шаровой мельнице до тонкодисперсной фракции, фильтруют и сушат, при этом при основной флотации используют собиратель-керосин и сосновое масло в качестве вспенивателя, а перечистную флотацию осуществляют на оборотной воде.2. Способ по п. 1, характеризующийся тем, что отделяют крупную фракцию с размером частиц крупнее 200 мкм, а мелкую фракцию с размером частиц 200 мкм и менее, причем алюмосиликатный концентрат измельчают на шаровой мельнице до фракции не более 20 мкм.3. Способ по п. 1, характеризующийся тем, что алюмосиликатный концентрат измельчают на шаровой мельнице до фракции не более 20 мкм.4. Установка для комплексной переработки золы отвалов тепловых электростанций, содержащая средства для разделения пульпы золы на крупную и мелкую фракции, а также флотации и магнитной сепарации с получением целевых продуктов, отличающаяся тем, что сепаратор пульпы золы выполнен в виде грохота, выход которого по крупной фракции соединен с входом первого участка для производства бетонных смесей, выход грохота по мелкой фракции соединен1. A method for the integrated processing of ash from heaps of thermal power plants, including the separation of ash pulp into coarse and fine fractions, flotation and magnetic separation to obtain the target products, which consists in the fact that a large fraction of ash is separated on a screen for use in the production of concrete mixtures, a small fraction of ash subjected to main and clean flotation, filtration and drying to obtain carbon concentrate; tail fractions separated during main flotation are subjected to magnetic separation and drying to obtain magnetito silicate and aluminosilicate concentrates, then the aluminosilicate concentrate is crushed in a ball mill to a finely divided fraction, filtered and dried, while the main flotation uses collector-kerosene and pine oil as a blowing agent, and clean flotation is carried out in recycled water. 2. A method according to claim 1, characterized in that a coarse fraction with a particle size larger than 200 microns is separated, and a fine fraction with a particle size of 200 microns or less, and the aluminosilicate concentrate is ground in a ball mill to a fraction of not more than 20 microns. The method according to claim 1, characterized in that the aluminosilicate concentrate is ground in a ball mill to a fraction of not more than 20 microns. Installation for the integrated processing of ash from dumps of thermal power plants, containing means for separating ash pulp into coarse and fine fractions, as well as flotation and magnetic separation to obtain target products, characterized in that the ash pulp separator is made in the form of a screen, the output of which is coarse fraction connected with the entrance of the first section for the production of concrete mixtures, the output of the screen on the fine fraction is connected
