Description
Данное изобретение относитс к области получени фильтровальных порошков из перлита .This invention relates to the field of producing perlite filter powders.
Р1звестен способ получени фильтровального порошка из перлита путем его помола и вспучивани . Полученный продукт содержит различные примеси в виде включений, s частности , железа.A method for producing a perlite filter powder by grinding and swelling is known. The resulting product contains various impurities in the form of inclusions, s particular iron.
С целью повышени степени чистоты фильтровального порошка, предложен способ, по которому вспученный перлит обрабатывают кислотой при температуре кипени пульпы и отношении жидкой фазы к твердой 4:1. При применении 3,-10 /о-ной кислоты, обработку ведут в течение 30-40 мин. После кислотной обработки из породы удал ютс примеси - окислы железа и других металлов, паход ш ,иес в виде включений. Вспученный перлит легко поддаетс кислотной обработке, так как при вспучивании поверхность значительно увеличиваетс , что способствует более полпому удалепию примесей.In order to increase the purity of the filtering powder, a method has been proposed by which expanded perlite is treated with acid at the boiling point of the pulp and the ratio of the liquid phase to the solid 4: 1. When using 3, -10 / o-acid, the treatment is carried out for 30-40 minutes After acid treatment, impurities are removed from the rock — oxides of iron and other metals, a pair of rocks, and inclusions. Expanded perlite easily lends itself to acid treatment, as the surface expands considerably during the expansion, which contributes to more complete doping.
Степень извлечени окиси железа из породы при кислотной обработке вспученного и не вспученного перлита приведена в таблице.The degree of extraction of iron oxide from the rock during the acid treatment of the expanded and not expanded pearlite is given in the table.
