heavy metal arm The invention relates to a, modifiable, [...], fertilize-effective soil substrate and the process for producing it by means of reducing cinder fusioniron metallurgy and of the operating process of. The usually, heavy metal and/or with high mineral proportions [...] waste and/or the phosphorus-containing material, for example, ash from the sludge mono burn, meat-and-bone meal, and/or other phosphorus-containing materials, and/or without addition of chloride-containing additives are alkali and/or alkaline earth metal chlorides and of sulfur and/or the use of a binder or with the addition of phosphoric acid as a function of their [...] hydraulically acting with the addition of binders and/or organic binders to [...][...] and with sufficient for the shaped bodies of coke-heated Manhole melting furnace in the melting process for the reducing or Manhole melting Carburetor sufficient thermal firmness briquetted, together with a solid, lumpy reducing agent, preferably fusion coke, as well as optionally with a lumpy, iron-metallic aggregate and/or a the basicity of the desired slag [...] added over the corrective aggregate the coke-heated shaft furnace, subsequently when in the shaft by means of the from the melting zone by the turnover of the fusion coke with the oxygen of the supplied and/or oxygen resulting in the melting zone via nozzles burn wind, from below upward flowing, hot furnace gas under expulsion of light volatile substances, while at the same time reduction of oxidic constituents until incipient heated melt flow. When coke bed takes place below the melting zone lying 1700 °C hot passage through said greater overheating, wherein heavy metals and heavy metal oxides are selected from the added lumpy in the reduced, from the phosphate and/or phosphorus-containing iron-metallic aggregate and the mineral material with good reduced to iron originating in the formed liquid slag phase iron oxides and proportions are involved. It stimulates a heavy metals, metal alloy and by granulation of the formed mineral, oxide containing, heavy metal-poorlava something similar a melt flow, in water ( [...] ) not-leach outablecinder granulates, which finely ground and with further fertilisers or soil conditioners is subsequently completed [...] with a fertilizer effect to a soil substrate. The A soil conditioner is preferably bio coal. |
