Reclamation of waste products in aglite production

Abstract

The effect addition of various types of waste products to clayey raw materials on processing characteristics of raw masses designed for manufacture of aglite grail has been investigated. To correct the composition of clayey raw materials by the contents of iron oxides, grinding sludge is examined. Oil-containing slimes are considered as a correcting additive by the contents of organic matter. The possibility of correcting the clayey raw material composition by the contents of iron oxides, free silicon dioxide, and calcium oxide is defined by an additive of galvanic sludges. As a correcting organomineral additive, settings of sludge banks at the plants of biological treatment of water of the housing and utilities and waste coal characterized by increased contents of iron and carbon oxides have been investigated. Application of the examined waste types as correcting additives to clayey raw materials allows us to obtain raw masses designed for manufacture of aglite grail with improved performances, besides to eliminate their warehousing in refuse dumps and holding lagoons.
