Process for the storage and dumping of waste materials

A method of depositing and ultimately disposing of special waste selected from the group consisting of blast furnace and foundry waste, SiO.sub.2 crucible fragments, furnace clearing for metallurgical processes, furnace clearing for non-metallurgical processes, clearing of boiler systems, dolomite, chrome-magnesite, furnace clearing from metallurgical processes with production-specific impurities, furnace clearing from non-metallurgical processes with production-specific impurities, cupola furnace slag, slag from non-ferrous metal charges, lead waste, aluminum-containing light metal waste, melting electrolysis slag, sintered ferric oxide, iron silicate slags, zine slag, aluminum-containing salt slag, tin ash, lead ash, blast furnace gas dust, ferrous metal-containing filter dust, non-ferrous metal-containing filter dust, electric furnace slag, blast furnace slag, converter slag, fly ash coke, glowing smoking ash, lignite ash, wood ash, boiler slag, slag and ash from refuse incinerators, slag and ash from special waste incinerators, used foundry sand, filling and blasting sand, limestone sand, ceramic waste, glass waste, asbestos cement waste and dust, waste washings, chamotte, activated carbon waste, activated carbon manufacture, rock and polishing dust, fine dust from slag preparation, coal dust, roasted pyrites, moulding sand, core sand, spent oil binders, graphite waste, dust and sludge, glass and ceramic waste with production-specific impurities, spent filter and absorption masses including kieselguhr, active earths and activated carbon, asbestos waste and dust, gypsum waste mineral muds such as red mud, enamel sludge and slip, graphite sludge, iron works sludge, steel work sludge, foundry sludge, glazing sludge, gypsum sludge with product-specific impurities, slakes lime with product-specific impurities, magnesium oxide sludge, ferric oxide sludge from reduction processes, non-ferrous metallurgy sludge, alumina sludge, nitrate, nitrite and cyanide-containing hardening shop sludge, barium carbonate sludge, barium sulphate sludge, mercury-containing barium sulphate sludge, glazing sludge with product-specific impurities, contaminated well sinking sludge, phosphate treatment sludge, surface finishing, calcium sulphite sludge, metal waste including iron-containing dust, iron and steel processing, lead containing dust, aluminum-containing dust, magnesium-containing dust, zinc-containing dust, non-ferrous metal containing dust, metal sludge including zinc sludge, metal grinding sludge, lead sludge, tin sludge, trowel sludge, jarosite sludge, gas cleaning masses, fire extinguisher power residues, skorodite sludge, galvanic sludg including chromium (VI), chromium (III) copper, zinc, cadmium, nickel, cobalt and precious metal containing galvanic sludge, oxides and hydroxides including zinc oxide, zinc hydroxide, lignite, manganese dioxide, alumina, ferric hydroxide, salts including arsenolite, boiler scale, metal salt-containing washing and rinsing waters, mineral oil sludge including honing and slapping sludge, oil-containing grinding sludge, shredder residues and filter dust from shredders, and liquid waste from housing estates including ground water from refuse and special waste dumps and oil-containing soils, said special waste containing constituents which under environmental conditions can be eluted and emitted, comprising the steps of mixing the special waste with contaminated setting water and a binder selected from the group consisting of hydrate of lime, gypsum hardening on addition of water, waste gypsum, cement and cement-like products, depositing the mixture thus obtained in a pourable state into holding means, and causing it to finish-harden therein.
